Hi guys, new to this forum. Just purchased a used Hensim 124cc motor (looks like Honda 90). Before I try to start this thing up, I need to know if I need to put oil in the stator chamber? There is a fill cap at top, but when I opened it up to install a starter motor, there was no sign of oil ever being there. I was told it had three speeds and a reverse. Anybody know any thing about these little motors? Your help is greatly appreciated. Cyclebender
