I cant belive that I havent got an anser to my question LOL
Air filter
What is a good jet size to go up to on a 300 fourtrax 1990 mod and a 400ex 2000 model both K&N air filters. I had bigger jets in my 400 but when I rebuilt the carb I forgot to get bigger jets and the ones I had are missing.

Thanks Moose You can have your cookies back now.LOL
What are you working on???Im making a custom air snorkel/intake/heat shield/quick release filter/cold air extension system thats close to completion.
The problem I have is with the filter. I need a flat one but smaller then the bmw stock filter. So does it matter if I buy any k&n filter to use regardless of size or shape? Thanks
