ya i too noticed the upjet part, and am a bit stressed to the fact that there are many trial and errors, and a lot of tuning is to be done to get the best results!!
but still if a good sound ad performance i got after the switch, then its good, but still didnt get the clear answer to my query!! so please help seriously because its taking a lot of time to choose!!

well i got my bike yesterday, but still didnt get an air filter installed because still confused which one to buy,will keep my search on until i find the correct match,but guys really need a K&N filter, and i had contacted a dealer here in pune to give me a list of filters which he has successfully installed on indian bikes!! will get it this evening!! lets see

dude,.. k&n is good..

but however be prepared to get a hell of problems if u do not get the jetting right... cos i got an k&n installed on my bike ( r1100) and i did not upjet.... the result is a damaged valve, damaged valve guide, blown engine seals and a bill of 2500 for repairing this... plus i am not getting a milage of 40 ( actually that does not matter but still)..

also now that i have got the carb upjetted ( redrilled the jets to 135 size) , the tuning is all messed up and the bike running like a total shit and highly unreliable..

The engine stopped working thrice and that too was just sudden... i mean the engine was working fine... i stopped it for a refuel and then it refused to restart...

check this link.....



i am still unable to get the problem rectified.. am now gonna switch to the stock filter and all...

my advice is first compare ur bike and an k&n fitted bike.. and if u are satisfied, only then go for it... if u have even the slightest of problems with the modded bike, STOP WITH UR MODDS ..

I know that the performance gains and the excitement of the new filter will be too great to overcome but the problems will pinch u hard later when the enthusiasm of the new filter wanes out.......

I was at the recieving end of such a stupidity so i am suggesting you.. else u will end up frustrated and deserted by ur bike in the middle of somewhere...

the take is urs....
whatver u go for, think twice cos the hh ppl are not idiots....

thanks for your reply ROCKRZ really appreciated it, well yes i am aware that,
upjetting is required after installing a K&N filter, because it sends in more air,
into the engine and the stock jet sends in the same amount of fuel, so to match
the high inflow of air i need to upgrade the jet of my carb.

i got my bike a few days back and i have already increased the jet size to 135, and still have the stock filter installed, i have also done some performance mods in the engine of my bike, and increased the rpm so to get better acceleration.
As i have already upjetted my carb then as far as i knw K&N filter will work fine.

i have overhauled the engine of my bike, got new valves,rebored my engine size,
surfaced the head,changed all the worn out parts as u can say, and now my bike is in mint condition.

so am looking forward to install a K&N filter and still a bit puzzled about which one to buy i mean RC1100 or RU0200?????

hey i have just got a simota airfilter installed into my 220 fi ... the roars brilliant and has also increased the top speed by 3-4kms/h.I had to make a slight alteration to fit the filter where i had to cut the filter box to install the filter got it done from krp here in delhi. Going for a trip tomm so would be testing it on the 2 day trip so if u can wait for the verdict it might be helpful.

simota airfilter , never heard of them anuj, and ya will wait for your feed back about the performance, cheers mate!!!

hey anuj could you give me about the SIMOTA airfilter you have bought for your bike?
