Alright.. when I got it... it was running a little rough, needed a little tuning. Well in the process of my 1st tune, It started to backfire. So Adjusted, well I took it for a ride and through the gears and hit 4th WOT and huge backfire. It blew off the tip of my silencer. I found that the rubber washer underneath the carb cap was torn apart, possibly leaking the extra air in causing the backfire. So while I was in the carb, I rejetted to 270. Put it back togather, and now an excessive amount of smoke is coming out.

I just noticed that my coolent bottle under the seat its slowely losing fluid, so most likey when it backfired I lost a headgasket perhaps? If the coolent gets down inside the jug what kind of damage or cleaning will I have to do? Will the coolen reach the crank case?

 

Alright.. Took the head and jugs off, well first there was tone of gas in the pipes.. The head gasket was fine.. where do I go from here?
