@ prafultripathy

acceleration and topspeed with sirac and 37t

now my bike takes long thie to hit 100 and does 136kmph@9000rpm in 5th gear that too in a small downslope

will changing rear sprocket from 36 to 37t help in acceleration .

I somehow had a feeling that the BOOSTER wouldnt work.
Now stick to stock unless u find a good engine tuner who can design one.

yess yaar....F**K em..now have to refill them with glass wool.....though it was surely revving free...after fitting stock again i can experience it..

Roller Bench figures

0-60 - 4.5 seconds (this can be lesser, mech can't shift properly)
Topspeed - 144kmph

Putting the 37T will certainly improve acceleration. If you don't care much about topspeed you can even put the P200 38T sprocket, that will give you as much acceleration as bike with a stock tyre.

Dude why don't you try that exhaust in your R1?

dude, he really owns the 'one?

Today went to pbk for getting a few things done. The one way clutch was supposed to be broken. But NO. It is working fine. Came to know that only after everything was opened and checked. My bike's silencer is gone. Makes noise of a metal piece inside. Also high beam has cracks. Will get them both under warranty soon. Planning for getting them when my bike would be serviced next time. That would be just before the time when it either clocks 20k mark officially (crossed 25k long back

) or becomes an year old (this would be on Jan 24th). Huge amount of work to be carried out then.

Presently my bike is on a very poor state of tune. Planning to hire a pollution check vehicle, take it to pbk and get the bloody AFR adjusted.

guys why dont one of our members design a nice freeflow exhaust for the 220 Fi?. in my view, JOEL is the right person. he has the potential to design & manufacture and can sell it online to members. these "Booster" thing which is being discussed since 2 or 3 pages is utterly useless. it simply increases the exhaust note to a bass tone & sure it does tremendous damage to the engine. So.... JOEL we are waiting for your comments & views on this topic.please come in.

^^^ didn't Prabhakar do that already?

ya, he did it, and i'v ridden his bike too. but what prabhakar did is he removed all the inner things of the exhaust. sure the bike's torque increased to satisfying level. but purposefully designing a free-flow is completely different. as u know, it will be done by taking into account the engine characters which will help the exhaust gases to flow freely which increases the torque tremendously & at the same time do lesser damage to the engine.

thats nice...y dint u do the test urself ? 0-60 i mean....
where was the roller bench?

**Prabhakar** · 12-04-2009, 07:06 PM

Spoke with Joel about developing an exhaust for the 220 - Both FI & the new SI.
After speaking with him I understood it is too complicated & expensive.
However He is ready to do that but need some numbers to make it possible.
I already have 2 orders for that.
Once I get 5 confirmed orders I'll be asking Joel to make them.
If any 1 from here are interested they can PM me.

**frankpilli** · 12-04-2009, 07:21 PM

ok, how much does it cost?

**gauravbalu** · 12-04-2009, 07:34 PM

depends on how many people are up for it..
now its 8000 with 2 orders it seems.. more the orders, lesser the price it seems..

**Prabhakar** · 12-04-2009, 07:36 PM

It'll come down if we can order in bulk as the material & fabrication costs will be lower.

**rahuldevnath** · 12-05-2009, 01:33 PM

Guys, can anybody tell me which side of the Air filter element, faces the rear (sensor), ie: the yellow or the white?

And if possible, what's the purpose of the two colours? I believe it has something to do with Air Filter Choked sensor.
