I wouldn't start it again until after you tear into it.

642MX, what type of fuel are you using for your 13.5:1?
Citgo 110 octane leaded. It will run with pump gas, but it pings a bit.

I thought you couldn't run leaded gas in these bikes? Would premium with octane booster be enough or go with U4. Its almost time for a new top end and i was thinking Wiseco.
You can run leaded fuels. Lead helps lubricate the valves, and leaded fuels are easier to dial the jetting in with. I've been using that fuel for about 3 years now. U4 is too expensive for me, and I wouldn't recommend the bottles of octane booster, they can cause some problems when used incorrectly. There is a company called Renegade Fuels, they make PRO102 race fuel that is unleaded. You may want to check that out if you don't like leaded fuels.
