I just bought a full FMF system to go on my 86R, trike is stock other wise. Anyone have a good base line on jetting that I could start with? My elevation is about 800ft here in central NY. I ride mainly wooded trails, many are tight. Any tips would be great!

Go to the FMF site, they have a base line listed in tech for you to start with.
