re: Dustom's Turbocharged Harley 1250

You are right, i guess time is right for giving a thought to a logo .
For a start i am inclined to having 3 words engraved on air cleaner cover. (HAMMERED by DST) and assigning a number on each bike i work on- mine will be 01 , his will be 02 . metal alphabet with chrome plating fixed on side covers / or between the V-twin cylinders

re: Dustom's Turbocharged Harley 1250

+1 to that. Maybe we are looking at "DC" design for Harleys.
Keep it up dustom ji

re: Dustom's Turbocharged Harley 1250

DC represents more or less an aesthetic mod job in automobile world. I probably would do more functional and performance mods .
We already have lot of aesthetic modders of bikes in every major city.
Performance aspect is hardly ever touched by them because it involves function n reliability engineering.

re: Dustom's Turbocharged Harley 1250

Very True. My idea for "DC" was as a short form for 'Dustoms Customs'!
Anyhow you will have to take care of the aesthetic part also in your "Shop".

Cheers

re: Dustom's Turbocharged Harley 1250


Dude, Hats off to you....

re: Dustom's Turbocharged Harley 1250

Its a great news, u just finished yours, and now you will get to play on second one so soon
great start for your own performance mod shop, i know you will have loads of fun.
it feels good to know that harley owners will soon have the taste of ur hardwork and pure passion.
hats off to you man.

re: Dustom's Turbocharged Harley 1250

Hi Dustom,

My name is Amit and I am very new to this forum. Infact this is my first post.

Like everyone else in this forum, I too am a bike lover. Did a bit of riding in my younger days in India, Nepal, Bhutan and in my home state of Rajasthan. After a gap of about 12 years I have now acquired an HD Iron, albeit used, a 2012 model. I had a few queries, would request if you or someone in the forum would help me:

1. I have to get some work done on the bike to make it a better tourer - rear shockers, better seats, some change on the handle to make it more touring friendly, rear seat and footpegs... while I understand all this can be done at the HD SC, I also know that I will have to pay though my $$$. So is there any other option available in Delhi, another shop in say a Karol Bagh who could do all of this?
2. Your GC Raiser - does it work only on Super Low or can it be make to fit on an Iron also to raise the GC to say a 130/135?

Request help pl.

Thanks

re: Dustom's Turbocharged Harley 1250

Already ordered the Kit for Him. Also ordered 15% stiffer Clutch Diaphram for both of us.
I Already had HD 1200 stock Diaphram spring with my kit along with competition clutch , Now HD 1200 evo produces over 90NM of Torque.
I am quite certain my Bike is making way more than that , causing that clutch slippage issue over 3.5-4000rpm. Its likely to be around 115nm now.

Thats the Beauty of a Sportster , these Hot ladies have been gracefully alive for so long that whatever Part you can think of , is available. In less than 2000$ ( roughly 1.3lc) you can have a 110-120bhp/ 150nm sportster and eat pretty much everything on a Drag Strip . That amount is actually less than standard 1200cc upgrade done at dealership which produces 70odd RWHP/90nm.

In USA parts are actually quite cheap , just that due to Huge duty and Shipping cost they become on expensive side in India. In Indian Dealership replacement clutch costs around 25k , Drag racing clutch setup are available as low as 200$ in USA from reputed Manufacturers.

Next bike will be done within First 2 weeks of NOV. Lets see If I get any more guys Intrested in Hotrodding their rides.
I plan to do things only on weekends and carry on my Job for atleast a year or two. Depending on demand will plan Future actions.

News form My ride: Milage has returned to its usual figure of 18kmpl in town and 22on highway. So have the engine temp. maintaining within 185-195*C , as she used to previously.

Last 200km left for Breakin , then will retune the ECU and Post some Acceleration Videos

----consecutive posts auto-merged-----

Amit ,
On making your bike more comfortable :
You could get Progressive rear suspension for Sportster( 412 series) Via Ebay. check out Progressive suspension website, they have some models with Xtra travel aswell.
There are various options on seats like Sundowner / mustang etc but all of them will cost a bomb from dealership.
Seats can be made locally but expect very poor build quality . HD leather is Genuine Calf leather sourced from Texas and Australia, it dose not deform/shrink / become hard even after years of riding in rain and snow.
Rear Footpegs: Could be Fabricated locally , but again Expect poor Quality and engineering on Locally made one. Not that no one can give you world class quality while in local fabrication but then it would not be day&night cheaper that OEM one.

Ground clearance Kit : It fits Iron just fine because Front forks and triple trees are same on superlow and Iron. Just that triple tree is finished in Matt black on Iron and in buffed Aluminium on a Superlow.
It would give you around 140mm of Ground clearance.

Very soon I will have Handle bars + Sissy bars + engine guards in complete kits on Offer , but you will have to wait for a month or two till I develop cable vendors.
Handle bars kits( Complete Kit with extended wires / clutch Cables/ Accelerator cable and Front brake hose) will be available in Mini apes / Ape hangers / Hollywood / Drag + some custom styles. Will Finish them in Chrome / matt black Powder coat.
For Touring I would recomend Mini apes on Iron. If you are in a Hurry you can order online from EBAY.

You would want a Wind sheild to make it long Haul worthy, Quick detachable ones from HD will cost around 30k. Refer your Parts catalog ( You would have got one with Bike) for Designs and part number.
You could also fix Royal enfield ones onto your bike , but that will Involve some custom made mountings

re: Dustom's Turbocharged Harley 1250

Thanks for the quick revert Dustom. I am in no hurry, can wait for a couple of months for you to develop handle bar kits.

How can I get the GC Kit from you? And how are they installed, is it a DIY job or will require a mechanic? How will it effect the riding posture since basically the increase is in the front.

I am in no mood to spend a bomb for sundowners (anyways I believe in the liquid variety ). Guess I will just explore some more in Delhi or get some made in camel leather from Jaipur.

Generally I have seen HD owners getting SE filter and plugs installed as stage 1. My bike has SE pipes but no stage 1. What would you suggest - stock/SE/K&N... or something else.

Pl consider this - I love riding but hardly anything on the mechanics.

Pl suggest.

re: Dustom's Turbocharged Harley 1250

Ok AMit, I will let you know about Handle bars and their details in about a months time.

GC kit install is fairly simple DIY job , actually Fitting risers is straighforward , bigger problem is Lifting the bike using car jack or something (I use wooden logs + Car jack).
when the Front wheel is off the ground + bike is stable , you can loosen Fork pinch bolts ( 2 on each side ) on the sides of triple tree using T45 Torx key. the forks will slide down as soon as loosened. Just Insert the cup of risers onto top of each fork tube, make the sit properly(measure using an inch tape or scale if both are fully seated on top of fork). stand in front of bike with front wheel between the legs
& Push both forks tubes(with risers) Upwards into the Top triple tree. This requires some patience and strength as the front end is heavy. Once the riser top end is fully flush with top triple tree, simply tighten pinch bolts .
I could give you Pictorial instruction on DIY when you order.
WHole process takes about 1 hour including Lifting the front end on jacks.
I could send the kit to you by Courier.


Every one until now who has installed has given very positive feedback about Handling , but they all have been on superlow. Which was very restrictive machine on bends due to 100mmGC.
If one asked for my prediction on Iron , I would say it will improve as front end feels lighter than before . Since it isnt a very expensive kit , you can return it to me even after using it if you dont like ( Now who gives offers like that), I know you will never take them off once installed , okok may be for powdercoating 5years down the line(lol) .


Sportster always touches the Speed bumps right below engine , very near to or onto side stand bracket. this Side stand bracket will lift up by about 35mm from present measurement.
Some forks recomend Nightster forks for superlow to increase GC , which cost nearly 35k and offer exactly 130mm of GC.
Infact Nightster 1200 used to come with 135 unladen GC till 2004. So in end you will get the handling of Nightster , and is fine handling machine.


On stage 1: Fitting a Filter or Exhaust is not stage 1. Fitting both isnt stage 1 aswell Infact makes the bike run like Crap at top end and overheat in traffic.
Stage 1 is Retuning the ECU with stage 1 filter and exhaust. Can you believe it , It gives 25% more power than stock and runs cooler aswell . It make the 883 a completely different animal. Thats stage 1!
Anyways as far as I can recall, SE stage 1 filter is also K&N housed in HD Screaming eagle fittings.
I would not use K&N or anyother cotton filter on my bike, unless I was racing.
So if you cant afford retuning the ECU, Just keep the Filter stock and enjoy that rumble.Its better that way in long term. Unless you plan to sell it off in year or two.
I am running a Esteem OEM Purlator Airfilter on my bike , It costs just 300 bucks from authorised Maruti workshop and is flowing Great. You can DIY it too but I would recommend Retuning the ecu as a must.

SE plugs are a rating cooler than normal and are handy if you use Stage 1 filter & exhaust without tuning as BIke runs much hotter because it runs lean. Other than that they are not of much use.

Why dont you plan a Road trip to Haridwar, Visit the holy city and get your bike souped up.
PM me if more details are required!

re: Dustom's Turbocharged Harley 1250

Here is a Cut section of My post made on TBHP about Stage 1 and Options

Q: What is Stage 1?
Stage one Involves letting the Engine Breathe better , Generally Involves Larger surface Air cleaners and Less restrictive Exhaust
. Can improve Rideability and power by as much as 30% ( Dynosheets are available for bike gaining that much after carefull tuning) , 20-25% is usual gain with after market tune, 10-15% for HD stage 1 download.
Changing any one (filter/exhaust) of them will Improve Air flow but will not Improve
it enough to throw the ECU into Open loop!

Q: *** is Open loop?
This Evolution Motor although seems straight out of WW2 but is actually quite techsavvy. The Closed loop system is where the feed back is taken from exhaustgasses to verify if the Fuel calculations done by ECU were correct or they needsome Improvement!
Evolution like many other Modern engines uses Standard Narrow band O2 sniffer sensors in Exhaust pipes and lets the ECU know what
exactly is going on!

Q: If sensors are already providing Feedback and adjusting Fuel delievery , then why a remap is needed?
Narrow band sensors are called Narrow band because they can only provide feed back while the AFR is between 1:14.3 - 1: 14.9.
They actually are only a Switch which provides on or off condition only on 14.6 exact , beyond which either way they can only read Lean or Rich but cant read How lean and how rich! that too only in range of 14.3 - 14.9 .
Harley ECU is set for AFR of 14.64 (considered very lean in HD world) for most of its Operational range( Light load or Low rpm)

Changing Both free flow air cleaner and Freeflow exhaust , flows lot more air through Motor and leans the mixture beyondwhat can be sniffed bystandard O2 sensors. and then the ECU starts ignoring o2 sensors output. Making the bike run like shit.

Q:Is this condition Critical?
Yes! in long term and
Indian Traffic jams , Yes absolutely!

Q: What about the bikes I have seen doing these upgrades and going on without a Problem?
Lean only causes Over temperature and loss of Power .
Harley ECM has something Builtin called EITMS (extended Idle temp management system)and air /temp based Timing Correction + engine temp based timing correction .When the Bike goes over a set temperature for engine Core / heads ( 230*c for Sportster) , ECU pulls out timing to prevent
Detonation and engine meltdown! But reduced advance also reduces a lot of power. Then what is the point of Stage 1 upgrade if Power is not prime , Just go for Muffler upgrade to enjoy that Harley sound!

Rear Cylinder Does not recieve as much cooling as the front and repeated Over heating causes Cylinder
warpage in long term. Leading to Head gasket leaks / Sepage! or the Push rod
cover leak. The Famous Harley Oil leak problem.

If you want to keep itfor an year or so and sell the Bike , or you are not going to get stuck in traffic
often, No problem ! Go ahead!


Q:No I love my Bike and I am not selling it Unless my Wife knocks the Court room! What are my Options Then?

Options:
1. Just Upgrade Muffler , and use it with Baffle .
2. Xides:
seems Bang for Buck but does not actually address The problem.
Cools engine at the cost of Fuel and Engine cooling @ 80bucks/ltr isnt very wise. It will cost you same as other more expensive options in year or two!
Also it provides over rich conditions where the Stock map is already (every thing beyond Half throttle is already rich )
Rich which messes with engine oil film on Cylinder walls. Either drop the Oil replacement Interval or risk chances of Oil pump Failure due to soot in Oil! ,
lot of Clatter etc.
All in all , You get what you pay for.

3.Standard HD remap VIA SEPRT:
This is One of the Best options if you only want longer engine life along with Fuel economy + warranty
Here The Harley authorised workshop Downloads a HD built Remap into your ECU , taking care of
extra AIr flow at specific RPM and Throttle Openings / Load etc. ALthough It leave plenty of potential Horsepower on the Table as it does not correct timing or AFR tables. Leaves them as stock, still meating pollution norms.
At almost 35k is
it Bang for Buck?

NO! Nothing is, in Harley world. Ditch that word , you are
now in engine Upgrade terrotory ! That shit will buy you almost additional 6-10bhp
bhp even in 883 trim and will raise the RPM limit to 7k!
Some people will pay that amount to hear what a Harley V-Twin sounds like on 7k with cannon shots!

And more over You got it wrong! its not 33k or 35k or whatever ,Its actually 40k for the package you pay for!
In 33k you just get a New Tune downloaded to your ECU and you get to go home with a Gold Biscuit sized electronic device called the SEPRT ( Screaming Eagle Pro Race Tuner) packedneatly in a white cardboard box.
It is a very capable device and tune almost every thing in an engine you can think of! plus It also has Built in AUTO-TUNECapability .
But It aint Tuning crap without pair of Cables & Software.
One to connect it to ECU and Other to connect it to Lappy.
Plus You will need to Purchase Tuning software aswell. Yes - even if you want use Built in AutoTune.
That is what the dealership does not tell you while selling you thatfancy gadget!

So most people Just get that Initial map downloaded using Dealership cables and software , and never get to use that Autotune Function
because they saved money on cables & software. They also leave lot of potential performance on the table despite paying almost 35k for one time tune.

4. Dynojet Power Vision.
Same capabilities as SEPRT Including Auto-Tune function as far as tuning is concerned , comes with Built In 4" LCD touch screen and does not need to be connected to Laptop for Tuning like a SEPRT.
At almost 44-46k Its pretty expensive , But its acomplete package with software + cables + Aftermarket Tunes + Tech support
Unlike SEPRT.

Q: Okie , Now I see Even the SERT will cost around 40k ,with Power Vision being around that same mark , which one Should I goFor?
They both have Same , Exactly same Tuning features. Both of them lock to
ECM on the First use so that you cant resell them . I cant think of anything
that would make SEPRT better than a Power vision , however Warranty might be
with SEPRT.
But be cautioned Warranty is only with Seprt if you have nottinkered with downloaded tune or have not run any Tuning sessions of your own.
If you have not Bought Cable and software then you have paid 33 k for Just one Tune and No autotune + data collection or data monitoring.

Q: Any low cost ECU flashing available?

You can approach someone who Owns a Power vision ( I do ) , he can get additional tuning license for like 200$-300$/ bike allowing him to tune your bike aswell as his. Flash a Dynojet / Powervision supplied tune for your bike.
This is best option for top horsepower and bang for buck.
Dynojet tunes are pretty accurate and much much better than HD official Stage 1 tunes. HD stage 1 tunes are nothing but extended rev limiter to 7000 and VE correction because even stage 1 has to meet Regulatory pollution requirements all over europe.
They do not have any timing correction or AFR correction. Power difference between HD stage 1 and AFtermarket tune will be of the order of 10-15%

I will compare feature by feature Between SEPRT and Power vision , then Its your call:
1.Tuning parameters
SEPRT: Same as PV
PV : same as SEPRT
2. Data Logging
SEPRT : 15 min worth of running time (64mb built in memory) + Needsconnection to lap top to start logging + throughout logging session (How are you going to ride with a laptop connected to bike?) and download logged data
PV : 40hrs worth of running time ( 2gb Inbuilt memory) + Laptop not required
3. Tuningon the Go!
SEPRT: can hold only 1 tune at a time , can only be flashed whenconnected with laptop + software
PV : Built in LCD screen , Does not needLaptop for any thing , can even review Logged data onboard + contains slot for 6 custom Tunes+ 1 stock tune at special slot , can flash on the GO!

4. Autotune
SEPRT:Passive Auto tuning @14.6afr , cannot load Auto tuning
results without PC connection.
Auto tune is Not as AUTO as it sounds-
VOlumetric efficency table is corrected in AUto tune , however that table is
laid out between RPM V/S Manifold Absolute pressure.
Although Auto tune will correct the cells on its own , but bike needs to be Going through all possiblecombinations of Throttle VS rpm which isnt perticularly easy thing todo.
What all areas did you actually go through in that RPM V/S MAP is only known when data is reviewed in laptop.


PV : Passive Auto tuning
@14.6afr. Can apply corrections without laptop.

What all areas / cell didyou hit and what all still need to be hit can be Monitored on the Go on LCD.
forEX you will know if auto tune has made recording for 4000rpm at 50kpa(10%throttle) and it has not made any recording for 4000rpm at 80% throttle , so youstill need to take your bike to 4000rpm while holding throttle at 80%( It actually is MAP , I am using Throttle % for understanding)

5. EngineMonitor:
SEPRT : You need to record data such as Engine Temp, AFR, Timing ,MAP, Injector duty , download into PC and review In software.
PV : Can bemonitored On the Go in form of Customised Gauge display of your choice on LCD ( 48 gaugesavailable in selection menu), Can also record and review on the GO!

6: Stocktune Reflashing:
Seprt: You can reflash but you are not allowed that without taking it to dealership.

PV: Reflash stock tune before going in for Service (30sec Job) , Remove Power vision cable from ECU connector ( 1min job) and your
warranty is Intact as dealership cant tell you have been running custom or after
market tune.

7: Tune quality
SEPRT: HD only supplies Tunes that areconservative and maintain close loop ( AFR is still maintained as stock 14.64 for all of the RPM range), they Just raise The RPM limit to 7k and correct VE .

PV: Power Vision / Dynojet supply 100s standard tunes for combination ofMufflers & AC , plus you can flash tunes borrowed over from reputed tunersabroad etc

8: Engine Size Upgrade
SEPRT: Supports Engine size upgrade to1200cc.

PV : Supports Engine upgrade not limited by size , 1200cc/ 1250cc/
custom size can be supported


One one the Most used Feature Of PV is Its Custom gauges:each and every gauge such as Oil temp / RPM / Gear position etc will cost 8-15k each from harley. In PV you get all these gauges on your LCD screen and get to play with backlite colour, digital or analog display, warning lights / shift point lights and all that Race stuff shown on TV

re: Dustom's Turbocharged Harley 1250

Should'nt this be made a sticky of some kind?

re: Dustom's Turbocharged Harley 1250

Thanks Dustom.

I think I should plan a trip to Haridwar!!! Most of what you said is French to me, like I said I am tech challenged . How do I pay you for the GC Kit?

I do understand the stuff you have written about air filter but wouldn't dare to do it myself. I will take your advise and go stock for now.

How do I PM you and what is your availability generally.

re: Dustom's Turbocharged Harley 1250

wish i had an harley... s super tuner is available right here

re: Dustom's Turbocharged Harley 1250

You still could!
I never saw it coming, just happened. One fine day became Owner of a Sportster.
I was very critical of Harley before i joined the Harley game!
