16 to 1 I am now at 100 plus degrees when I ride.
When I stop a a light the waste heat from the air cooled engine is leaving marks on the inside on my left thigh , OUCH
For some reason I always put my left foot on the ground when I stop???
I would think if it was good the engine would be running cooler correct me if I am wrong,last time I was running super hot it was about a head gasket and a crack in the housing.......just a thought.
