no issue with warranty and insurance.. already two users on xBhp named satan69in(tejus) and a.umesh(umesh) have tested my bike.. they own the new P220 DTS-i.. they were pretty surprised by my bikes braking and wanted to get it fixed onto theirs.. u can even consider their views.. my bike's rear tyre doesnt have much grip.. it may last for another 3k kms.. i would be happy if my bike is used for the testing purpose.. please include prabhakar anna's bike also..

No Problems with warranty as My Bike got warranty related things done aftr fitment of the ABS.
U can test my Bike too.
No Issues.
Also U need to consider the Tires & their conditions while testing.
Rahul's front braking is way ahead of mine ( Due to completely worn front tire).
My rear braking is better than his as mine is a new IRC (2500kms old).
Both of us have the ABS(Mechanical Pump) fitted all around.

Did you verify with your dealer?

Prabhakar, any comments on this?

ABS saved me today

Hii..
today i was driving fast on a fly over as i was running out of time to go the SBI bank and deposit money... i overtook a car and came in front of it. another car infront of me was quite far, so i opened the throttle and was roughly on 90+, but suddenly the car applied the brakes hard as it was half on the other side of the road and a RTC bus was coming fast from the opposite direction.. i applied the brakes hard, but to my surprise i found that the bike stopped without creating any kind of danger and the rear wheel, which got locked, dint slide much.. my tyres are not that good and the road was also in bad shape, with little gravel on the road.. but in the end i scared the shit out of a pillion girl who was on an RTR .. if the ABS wasnt there, i seriously would have been in bad shape by now...

Sorry For the Delayed Reply.

I considered some basic things here.
No High end testings or calculations.

I tried this out with trial & error methods to fine tune the setup.

The things I considered here are the basic Functionality & release of Power.

I still remembered the RX135 with the silencer removed completely used to increase the power very much - we tried this out in our college Project.

I don have those details as this project was done by another group & none in the group are in Touch.

I remembered that the constrictions to reduce the sound & Pollution actually acted as a hinderence for the exhaust air to go out of the engine.
This made the engine work harder to send the gases out of the exhaust pipe.

So I simply removed those hinderences from the exhaust.
I planned to increase the volume of the small expansion chamber in the exhaust.
But one of my friends who is in US now advised me not to do that.
Reason the expansion chamber will not have much role here as the position of the expansion chamber has to be higher than wht I have now in the set up.
Which may not be possible easily & involves complex calculations.

I also saw that the weight is reduced by good amount.
The weight of the components removed from this are around 3kgs.

U can term this as an improvised FFE from the stock silencer.

I saw tht aftr this tht vehicle was running very lean.
So made the AFR rich.
But still it needs some more tuning & a good free flow Air filter.

I rechecked the speeds with the roller bench & thy were near about the same.
Checked the Pollution at the end of the exhaust & it is still under control.
CO is 1.89 now.
It was 1.03 before free flow.

No other tests were done.


@ Rahul

What R U trying to do???
The ABS is not a device which can prevent things.
Please Don try to test it too hard.
It is only a simple mechanical Pump sort of device.
It does not have sensors or any other things.
Please avoid such type of high risk driving.
UR life is precious than a couple of minutes delay to any work.

No offence, but I would like to make a few things clear.
Tuning is not done by keeping some basic and vague thoughts. Inputs have to be accurate and defined.
The working principle of an RX135 and a 4-stroke engine is not the same. Both work on opposite principles when it comes to exhaust tuning. An expansion chamber will kill a 4-stroke engine and vice versa.
So if you said the RX135 in your example was making more power without an exhaust, its a moment of amusement.
If you are developing a product for your own usage, you can afford to do it all. Make or break, coz nobodys money is at stake. Its just your own money. But when you have decided to start selling a product, then you need to ensure the results are right and the customer get the best for money.

Coming to a performance 4-stroke exhaust.
You cannot build a well performing exhaust without the right inputs. You need to know the values of the various variables in your engine and then target your peak power rpm and then design the right pipe. Every cross-sectional dimension in a 4-stroke pipe matters a lot and its never easy to build a good pipe. Any free flowing pipe makes noise and makes you feel you going fast, but it wont in reality.

A well built exhaust will improve the entire rpm range and again you can build a pipe for whatever range you want. Provided you know what you are doing with your engine.
A few inputs that you need to know while making a proper pipe are, your valve sizes, valve timing, rpm desired, cubic capacity etc. Unless you know these variables, you are heading no where.

In desperation to simply build an exhaust, please do not forget that the best exhausts are not a joke to build.
Removing the baffles inside the exhaust and also pulling out the cat-con will do more damage than good. It affects the wave path and the tuned lengths are messed-up.
There was a time when I gained over 1.5bhp on my Fiero 200 by simply tuning the exhaust and nothing else. My R15 wont run without my freeflow and the exhaust alone contributes for over 10% power. An exhaust should change the character of an engine and then redefine the power delivery.
I have not seen even one well built exhaust in this country. Be it Automech, KRP, Remus, Petes, Proton or whatever. All are simply selling psychological bhps.

running a two stroke without an exhaust will never make it run right, and not just that, the vehicle will go into runaway detonation and kill the engine before you know it. This is by far the most ridiculous statement I've heard here

FYI, a tuned 2 stroke exhaust [an expansion chamber] works on sound waves..How can you make a statement like that man? I'm really amused.

in that case it doesn't make your exhaust any different from the dalda dabba exhausts you get locally. They create a huge din, have worse emissions and have zero R&D invested in them.

No offense man. Just telling you what I feel

Cheers

sorry anna.. u know how difficult it is to drive a P220 slow...
to be frank i have stopped driving fast in the city unless its very very urgent.. iam not crossing 60 kph.. on empty roads i hardly cross 70 these days.. but when provoked i rip hard... and dont worry i have pretty good control over the bike.. .. i was just trying to tell how the ABS was helpful to me in various situations.. almost each and everyone comes across such hard braking almost everyday.. i'll be careful from now on.. and bhaad main gaya SBI .. that lady dint accept the money as i was late by a minute.. i felt like thrashing her with my new AGV

Dude, please ride safely and responsibly. I know you have good control over your bike, but then sometimes things take such a bad turn that you cannot do anything to save yourself and end up in a mess. I am saying this out of my experience. It is better you understand your responsibility towards your family and others on the road in addition to yourself. Ripping in the city can just save a few minutes but you should understand that your life is more important than those few minutes.

Ride safe and responsibly.

I was qouting the RX project as I feel that was the first point in my experiment.
I designed this as a trial & error method.
I don have any means to calculate things.
I don't know whether it increased the power by 1bhp or 10bhp.
All I knw here aftr all the experiments is that the Top end has increased by an impressive 4-5kmph on the Roller bench.

Its made for my use for the IBA Run which requires Higher topend.
I did not make it for selling as of now as the exhaust is not yet final.
I also need to make more tests in individual gears, RPMs & then also the mileage.
I still doubt the high mileage as my bike was running too lean when I went for the previous ride.
It only it went into the right direction.

I used the stock 220 exhaust & tried to tune it.
The sound increased initially but now its not so loud.
U can feel its different from a normal 220 but not a great deal.

I tried out some drags with another 220 & there is a remarkable improvement in that front as well.
Was pulling away from him in all the gears.
The RPM climbs up much quicker to the redline.

Yes in the desperation I may entirely ruin the exhaust.
So checking after each & every change with the roller bench & Drags - Only 2 means to check for me.

Any input & the harshest criticism is welcome here.
It'll make my exhaust better.

I just Gave U some basic Ideas behind my Plan to create the Exhaust.

I don have the full details of the project nor I remember all thy did as it was 8years ago.
I do remember tht I too checked out & ran without the exhaust for 2-3 days.

I told U right I just tried in the same lines as their project.

Yes U can call it a Dabba Project too (its too primitive).
The emissions I rechecked after the fitment to be reasonably ok(Under 2).

I checked on the roller bench the the top speed has increased.
I was aiming at this only.

I'm sorry My statements are from only what I remember vaguely from the college project which some of my friends did.

I consulted 1 more guy in US who worked on tht project only for some time & Currently working in Ford.
He also asked me not to fiddle too much - so only did what both of us can remember.

Yes the R&D I spent is only a negligible 25-30k for the whole project( Sprocket changes, Exhaust, brakes, etc.,).
Which can be said as nothing.

No offense / Hard feelings.
I would definitely Appreciate if U guys can give some inputs.

Instead of saying remarkable improvement; can you give us some numbers?

I can only test the Speeds with the roller bench.
If U need any other numbers & Tests.
I'll give U My Bike!!!
Please test it if U have any means to test the numbers.

well, IMO we should avoid Peacock Terms when making claims. Because your statement doesn't give me any insight into the improvement in the performance in any way. If it really improves the performance, you shouldn't have any problem getting some numbers.

btw, You did not reply to whether you've verified with your dealer about the warranty and insurances if we install the aftermarket ABS system.

I was able to beat stock 220s with ease in a Drag race.
I was not even ducking nor trying it too hard.
Top end was on the roller bench in the Service center.
I also got similar number on the highway when I used GPS to check the top Speed.
I reiterate I do not have any other means to test the numbers.
I would be very much happy if U can check it if U have any means.
I'm not angry or annoyed but its my inability to procure the devices to test.
Please go ahead & test my vehicle if U have options.

If U want U can check with people who checked my vehicle.
They found it quite good.
I don wanna comment more on this.
let them say how they felt after the changes.

Which Dealer U mean??
The ABS dealer or the Bike dealer??

Once again no hard feelings or offense.
I really love to get feedback.
