Re: Held The ***** Hostage , until She agreed to Go Faster!

well..
First real heart pounding moment came after the First 10sec heat cycle.

On second heat cycle , when I touched the starter , it couldn't turn over the
motor.
I put the bike in gear and tried moving the motor by pushing the bike and rear
wheel just locked up not budging at all.

That was the time when I started
having technical shit thoughts of Microwelded rings , Seized up pistons and what
not. ohh god why did I even opened up the Motor of a bike barely an year
old.

I was about to start taking it apart when I saw that blinkers on the
bike are barely glowing.
Damn! the battery is low , got hold of a Big car
battery , jumped the leads and there she goes. Purrs like a Kitten. No dramas

So, Now I have done first 100km on the new motor. It pulls like a Freight train already. everytime I upshift ( specially from 3 to 4th or 4th to 5th) , it gets into that acceleration mode even without throttle. Although I have the Breakin tune loaded , which is quite conservative on Timing and rich on fuel to keep temps down , additional power already took me by surprise a couple of times. Soon will run the Auto tune utility on Power vision and get it to correct the VE throughout the range.
In Breakin miles, taking it very easy and trying to keep it between 2-3k rpm.
NO leaks/ no weird sound. Infact I feel the Motor is very very quite after installation. Stock motor was very noisy on valve train noise , One could hear the push rod lifters hitting rockets every time , all the time. Guess Harley mainatins more clerance between valves and tappets than actually required. They sound like a Singer sweing machine if One has quite mufflers.
But now New cylinders + new packing gaskets etc have Have stacked up so nicely that Motor has no Valve train noise atall (well atleast not presently).

This is Most bang for the Buck upgrade for 883 , and I would strongly reccomend it to 883 owners. and since 883 comes with same crank + clutch + Gearbox + driveline components etc as a factory 1200 , it is pretty reliable as well.

pics pics pics.. of the new souped up 1200 motor...

Re: Held The ***** Hostage , until She agreed to Go Faster!

LOl. its actually 1250cc now.These new Buell cylinders look exactly same as before on the outside. same fin style, same overall size. Inside they get 3.5inch bore with stabilisers instead of stock 3" and get Forged High quality reverse dome pistons.
SO not a difference in how it looks ( quite a sleeper).
Only give away is Hammer LOGO casted on cylinders instead of HD.
Racing Clutch and few exhaust components are still remaining to be Installed. will do them up on this weekend. then will Polish the Bike and polish the chrome bits.
That will be the Time to post Complete bike Pics.

Re: Held The ***** Hostage , until She agreed to Go Faster!

News Update - completed first 200km on the Fire breather. still running the Breakin tune. which has 5* timing lower than the regular tune to keep the temps down.
There was some concern in my head as to how will the high compression (10.5) take Indian Fuel. I have filled regular fuel as I always use , and has not faced any Issue of detonation etc atleast on this tune.

Well I decided to post today just because I havent wiped my smile since morning. And there is a Good reason . Today morning was the first time I gave it a Bit of stick.

Slowed down for a speed breaker , accelerated gradually , shifted to 2nd at 30kph or so and wacked opened the Throttle. Damn! It hit me! Front wheel was off the ground a Good foot or more. I had to back out of it .
Now I have my reservations! This Sportster is Dangerous!

Re: Held The ***** Hostage , until She agreed to Go Faster!

Great example of in house engineering and hats off to your passion, knowledge guts to tame the HD Motor parts to an extreme motor. I think all Sportster fans, owners, would be owners would want more than a word of advice if anything of this magnitude is to be done. You've completed first 200kms with your 1250cc sportster although you have narrated the difference in power very well but also keep us all posted with some pictures and/or videos to actually feel the 1250 power visually.
Great work Dushyant Bhai!

Re: Held The ***** Hostage , until She agreed to Go Faster!

Still some work remains to be done, like - exhaust is missing its shields, most of the under tank wiring is hanging shabbily , a good launching clutch is waiting to become a part of motor , most importantly I am still tuning the ecu , finding the sweet spot of timing advance for new motor.
Soon the breakin miles will be over and will post a few videos of 0-100 , 0-160 etc..more pics will come in aswell.
Thanks for posting in.

Re: Held The ***** Hostage , until She agreed to Go Faster!

that is one hell of a mod, from increasing gc to power tuning and converting from 883 to 1250. and i know you are not gonna stop there
hats off to you dustom_99. driven by pure passion.
i am hooked to this thread now.

Project completed: Some Pics of the Lazy Gal.

re: Dustom's Turbocharged Harley 1250

Lazy gal is awesome .
Looks like the video is set to private, unable to view.

re: Dustom's Turbocharged Harley 1250

My bad! Video has been made public! Its just for sound at Idle.

re: Dustom's Turbocharged Harley 1250

Little busy at work after I came back from the Ladakh trip. So couldn't follow up the threads.

Beautiful music to the ears. Royal Rumble.
Excellent work @dustom_99. Wish you were in Bangalore.
Hats off to your passion and commitment for perfection.

And don't forget I will be contacting you for the GC raisers in a short time (after I get my superlow)

re: Dustom's Turbocharged Harley 1250

Dont worry about GC kit , I can send it within a week of your request. Ride around a Bit ( 1k or so km) before that, get used to the Bike. Notice the places it scrapes the bumps usually , notice how it handles the corners and how far you lean into them before foot pegs Grind.
I want you to get confident with the stock bike , accelerating , Braking ,handling etc.

Then install the Kit and get that Real sportster handling!



Just a Few post ago some one mentioned opening up a performance shop for Harley! Hear this-
Last evening I was bar hopping near Rishikesh where I Crossed a Hog on Superlow from Punjab. We waved and went our ways. While later he took a U turn and came along side me. exchanged greetings .
He said he noticed that I have a Local number on my bike, wanted to know good places to visit in Rishikesh.
Conversation turned to My round Air Filter ,Told him I designed it and its performing great. I also told Him I have Stock mufflers customised

At that point he asked me If he could take a Ride and feel.

SO we exchanged Bikes (Asked him not to Lug the motor at anycost), His was 2012 with lot of Asthetic goodies and SE mufflers with stock Air filter.
I was very Nervous as i have only 3xx KM after the kit, but I could not say no to him. He asked me with such persuation.

Both of us went beyond Rishikesh and into the twisties. some 20odd km later ,he halted, took off his Helmet for first time and was Like WTF dude. what is this bike? this is not a Superlow. I Showed him the Hammer logo on cylinders and told him its a 1250.

He was like: Dude , I am not a Techie but I want whatever is in there!
I told him the Budget , and he was basically like : rip me off my Money but I want that bike.


We went our way after a can or two of drinks , and by 11pm at night I go a Message from my Paypal account that 80k has been added to my account from such and such creditcard. shortly after I got a Message from his number : please order new engine for me too( he actually wrote engine).

So , he will be sending his Bike over In nov!

Guess the Speed shop will come through before I actually thought about it!

re: Dustom's Turbocharged Harley 1250

Yes. I will do the same.
I was just worried since in Bangalore we have lot of unscientific speed breakers and I am not used to ride/drive a vehicle with such low GC.
Anyhow since I have taken a plunge, I have to learn to swim.

re: Dustom's Turbocharged Harley 1250

500km done, another 300 to go!
Then a regular oil and filter service to be done.
No leaks , no fault codes ,No noise.
Only problem is : so much for 300$ competition clutch and it still is slipping sometimes. I felt some weird throttle response in 5th and reviewed the logs of run. above 3000rpm , every time I open handfull of throttle , the revs rise without corresponding increase in speed.
Specially in 5th gear .. May be I will have to order extra strong clutch diaphragm spring , or the Bit** is going to chew up the Clutch!

re: Dustom's Turbocharged Harley 1250




you built one... and the second one has already started.. once that bloke gets his supercharged twin it will spread like a wildfire as the posers will do..


it,s time you start designing a logo for " DUSTOM CUSTOMS". seriously happy for you.. gharwalo ki baat sun leta to mai bhi engineering kar leta
dealing with stupid computers...
