@flyingabhi: Which oil do you use for the filter?

sorry for the late reply...i was on a week long trip to Valley of Flowers

i use 20W50 (the normal engine oil)

No probs mate!

Expecting some pics frm ur VOF trip...

Whats your cleaning interval? Do you wait for the airfilter choked icon to flash before cleaning?

nothing wrong in trying out... if u are satisfied with K&N u can carry on.. or u can take it out and sell it to some of ur friends.. u'll be satisfied that atleast u gave it a try.. for increasing the acceleration decreasing teeth on front sprocket can be given a try.. how about 13T sprocket for the front.. there should be marginal increase in acceleration.. but there would also be drop in the top end by almost 3-4 kph.. simultaneously we can try 38T rear sprocket also.. combined together should give awesome acceleration...

Actually, a 1T drop in the front sprocket translates to about 2.5T increase in the rear. So, technically, the acceleration should be a lot quicker, and the top end decrease should be 9-10 kmph.

I don't advise this at all, since the 220 Fi is already short geared. I'd suggest going the other direction, making it taller geared. I was thinking of putting the 36T from the 220 DTSi to my bike.

Taller gearing also means lower torque, even this is undesirable especially in lower gears ?

BTW, Why all these mods required on powerful bikes like P220 (the most powerful bike in India)?

1st, 2nd & 3rd gear are really short, with a slightly taller gearing (36T rear) the torque will be still enough to pull through all the gears. So city riding will hardly be affected.

These 'mods' are needed on a powerful bike like the 220 to make it more relaxed while touring...

a. Anyways, a teeth added/deducted either to small/large sprocket affects torque across all gears by some percentage (percentage is more in case of smaller sprocket mod than larger one), but torque/speed gets affected for every tooth added or deducted.
b. Relaxed ? not by mod'ing gear ratios

but 'longer stroked' engine is more appropirate.

omg! thats way too much than i anticipated... even iam planning to shift to DTS-i's sprocket after 5k kms more...

Ofcourse it affects all gears, the sprocket cannot be gear specific

But since you were concerned about the loss of torque in the lower gears as you mentioned in your last post, I pointed out that the torque is so much in the first 3 gears that the lesser torque will not be an issue.

If you are into body building you can't end up looking like exactly like Sylvester Stallone, but you can probably end up building a body like him. Similarly we are not trying to relax the bike as much as a long stroke, just making the gearing taller to help with better cruising....

Anyways,the longer stroked equivalent in the market puts me to sleep, I'd rather have a slightly relaxed gearing on the 220 instead.

a. My lines in different english

b. What an analogy sirjii !

! Anyways these mods bring temporary satisfaction, I have seen numerous people reversing their decision after a while.
BTW, What was Bajaj (manufacturer with multi-crore budget for RnD) thinking while making this bike ? They didn't think of touring or relaxed riding ? This Q for Bajaj not for you !!

there wont be any performance change except for change of exhaust note.. instead ur bike will become excessively lean no matter to how much u change the co which is due to the open loop FI in our bikes... it may lead to the damage of the engine

Hey monty my buddy..... i think rahul has answered ur question.... moreover..... all i have to say is there will be an increase in the sound from the intake..... the air being sucked creates a tremendous roar.

.. i once took off my airfilter to check how it is... i was compelled to start the bike... my bike was roaring any LiOn can at just 4k rpm..... i woke up some neighbours too... at 6 in the morning..

.... more over the fi system in programmed to take in specific amounts of air only.... not more not less.... u very well kno the fi system works on a pre programmed BrAiN

... it really doesnt matter whether u put a K&n or any other filter..some may beg to differ from this opinion but this Is what i have to say.. im not gonna invest on a filter for my bike.. when no visible output can be experiences..marginal output YES !!! but enthusiasists most of the time(always) will expect more than a marginal increase....

My bike's right rubber peg fell off!

Only the metal rod remains!

Some hard rain riding in Lavasa today.

Fact for you: Bajaj did not intend on selling this bike as tourer. Its a street bike for intra city commuting. And its gearing does not have to be relaxed for that purpose, Bajaj with its multi-crore RnD as you put it actually got the gearing spot on!

Though we can't call this bike as CBF, but it indeed is a City Bike with a Fairing!

It does have as much power as the smallest CBF.

About the FI. the K&N should work even without the closed loop system simply because it should have a MAF sensor at the throttle body to detect the actual amount of air flowing. Only this will allow the engine to keep the CO2 setting set at the service station, Infact you only set the constant for the MAF sensor while setting the CO2. The system cannot adjust this by itself because it does not have a O2 sensor at the exhaust(catalyst). Though the pump might have its limitations, which might get affected at the top RPMs.

Btw, performance of the IRC remains un answered???

Sorry dude, I logged out without answering & did not log in the Week ends.
Well I am satisfied with the grip it has provided. In wets, well, I tend to become very conscious. So really cant tell if its better or not. But next time I would go for a similar profile tyre as the stock. I have lost the top end, so not quite satisfied.

Ok every one I have one question. Since ours, i.e. P220 DTSFI is also oiled cooled only & the newer one also but I guess it has got a bigger oil cooler, so if we replace our's with the newer one, will there be any increase in performance. I meant to say will the oil run cooler?? Hope I am clear with my query
