I'm considering changing my stock filter and jet. The filter of choice is the K&N and a larger jet. Should I foresee any complications, any advice would be greatly apreciated. IS THEIR anybody with the same modifications, what was improved?

 

If you do it please let us know if you thought it was worth the effort and money

 

From the number of people I've talked to, you will not see any noticable difference on a 4 stroke with intake/jets alone. You'd have to do exhaust as well.
