Im buying a K&N air filter with an outerwear, and taking off my lid to the air box. What kind of jetting would be required on a stock 06 450er? And would the jetting change again if I added a slip-on? Can someone please point me in the right direction...thank you.

search... there is about 10 threads right now on jetting. i have on of them. to get you close go with 160-162 main jet. and then go from there. you may have to get a smaller leak jet but just try and see before. and yes a slip on is going to require a little tunning again most likely. jetting is not hard its just alot of trying it out. get a 160 main jet and you will be close though

Thank you
