My son's EVO 80 Jr fires up no issue and runs well, but it drools a remarkable amount of orange-tinged goop from the front of the silencer, to the point of being embarrassing. It's wet almost like coolant and oil mixed, but the bike doesn't seem to use coolant and it doesn't smell when running. Our trials are mostly dry, although I do wash the bike with a power washer. As a related aside we're running 80:1 Motul 710 mixed with non-ethanol gas.
Thoughts?
