Have in mind that K&N is less restrictive than OEM filter. That somewhat affects the fuel/air mixture (less so with the K&N OEM replacement filter than the pods) and it also lets larger particles into your engine.
That said, I had K&N OEM replacement filter in my Kawi 550 for more than 10,000Km with no ill efects and no re-jetting needed. I think K&N recommends about 10K between cleaning, depending on the environment.
I have an 02 1200S
Has a holeshot exhaust,timming advance,and stage 1 mod done!Has the hole cut into the top of the air box.
I currently have my bike apart,wanted to check the AirFilter,she has about 11500 on her!
The factory filter is Dirty,needs to be replaced!
None of the Stealers around here have 1 in stock.
The Stock filter is $29,will take 4-5 days to get!!
The stock K & N replacement is available locally for $55
I was going to go buy the K & N today,but this forum has me Rethinking that decission!!!
Is it true I will have to ReJet to a stage 2,just to install the fact replacement K & N,or will the stage 1 be OK??????
