New to the forum here. Just recieved an '81 Yamahopper from my uncle. Seems motor is locked and needs some TLC. I heard these are 2 stroke engines but, I notice an oil fill plug on the crankcase... Should I start by putting it on end and letting some WD40 soak in for a bit to free it up?
 
Thanks,
Tonka

depends on what is froze up. could be the piston, or something in the crankcase. fill oil up to full mark and try turning the flywheel.
