new hmf and k&n

[Sparky_20]

alright so I just bought an hmf sport series slip on, a k&n and an outerwears cover. My elevation is 200ft, will be riding in 40-90 degree weather in sunny washington state. What jetting should i buy? thanks!

I just put an HMF on mine and removed the airbox lid. To start with, I put in a 158 main, moved the clip on the needle down 1 position (to raise the needle), and put in a 42 pilot. I'm at about 900 feet so it should be real similar. You may end up going to a 155 main or up to a 162 depending on your bike etc, but that should get you in the ballpark.
