I have a new ’06, I’ve : 1. pulled the snorkel and plastic thing from the air box. 2. Put a 172 main jet. 3. 68s Pilot jet. 4. The stock needle is on 4th clip from the top. 5. New "uncorked" carb. manifold 6. FMF Q2 slip on with stock header. The problem is that when (at 3.5 – 4.5k rpm) I try to roll on the gas nice and smooth, It doesn't, it kind of jerks / snaps in. the same applies when I try to roll off the gas. It kind of Snaps shut. So I end up with a bit of an “On / Off” switch feeling. It may in fact be doing this at higher rpm, but it’s most noticeable at these speeds In the tight stuff….. right when you DO NOT NEED THIS !!!! Help!
