Re: Problems 80cc Jet bike motor??
Did you break in the motor first or just pin the throttle from day one? You may have blown your top end. Did you plug up the hole the wires go through into the magneto case with sealant? RTV sealant will do a good job keeping water out of that area. The other 10% of rubbing alchohol is water. Bad for fuel systems. Engine parts should always be cleaned with mineral spirits.
