I just recently did a rebuild, having a few issues but should be able to work them out, however i have a question. How much (in oz) gear oil do you put in the crank case? My friend did most of the work and he filled up when done. I know that after the break in period you should drain and re fill. what kind and how much? He recomended 80 90 lucas gear oil...
 
Any 4 stroke 10w 30 engine oil with no friction modifiers.

Auto trans fluid type F.

An oil designed for motorcycles with wet clutches.

Personally I prefer option one but they all will work just as well.
