If you are using modern pump gas it really leaves very little color on a plug. If you use race gas then you will get a little color.Much better to get a good baseline from the factory boys before you go and then ride it there to see if it is going to work. All my Gassers have run better at high altitude with a richer pilot.Less air pressure,less vacuum to pull gas through jet.Bigger jet needed to compensate.Make sure your reeds are new or close to new. That will help with jetting.
