OK Trying to figure out what happened to this motor. New topend with about 10 minutes ride time. Bike was not rich previous to this topend. if you notice it burn off the top to the 1st ring on the exhaust side. also the tip of the plug burnt off. but the piston top and insert are bblack with carbon and everything was oily. some slight presence of detonation around the outside of the piston. squish was set at .028" it was ridden in some crazy deep sand though. Pics are as close as I can get without beeing blurry. oil was motorex cross power 2T. premium pump gas.
