Sorry, the carb is a round slide. The pilot is a 40, the mian is 340, I can also get you the needle # and slide if you need all too. The spark plug is the racing plug from NAPA. They didnt have the regular one. Does any of this help?

dnmac1999:
It is an NGK plug, just not the cheap one. Its heat range is 8. My alttitude is also 2000-2300. The year is 86. I can get it jetted, just wanted to make sure that noise i was hearing is what i thought it was. Ill have to try the gas and see if that works i guess.

BDI:
My bad usually if some one is using a plug from the auto parts store it's a champion plug,Sorry for making assumptions.There are many different things that can cause detonation even carbon build up can do it. I hope you figure it out before your bike s**ts a piston, good luck to ya.
