I changed the fluids a few days ago and I'm trying to figure out how to tell how much oil the gearbox should have. It sounds easy enough but with no gearbox dipstick and the owners manual not being a big help I think it may be slightly over filled. The oil dipstick is at the correct level.

It seems to shift a little harder than it should and pop out of gear once in a while (didn't do this before the change). If I remove the gearbox fill plug oil leaks out so it definitely has fluid, the question is how can you tell if it's too much? Also I'm not sure but it seems to also get a little oil from the rest of the engine oil??

 

Wouldn't the gearbox share the engine oil like the new ones? Both of my bikes are setup like that to where you only check the engine oil.

 

Yup he is right, the engine and gear box share the same oil. Just use the dipstick
