How do I use this tool?

I'm 90% sure that puller is for many Honda's and a few other makes / models. I bet if you look at the threads on the Big part they are left hand thread. If so that puller should fit these Honda 's: late model 110's, 84-85 125m's, and 185-200's ( not the 200x's though ). It will also fit a few other machines / models also. I can't remember which ones though. I do know it won't fit your Yamaha though. That one takes a different style.

That tool is for the type flywheels that are not bathed in oil. It will fit about 90% of those type. The outer part has reversed threads on it, and screws in, then the cneter screws in and popps it off. Yours does not take that type. Ive also found that the inner part (bolt) threads right into alot of flywheels that require a single bolt type puller to remove them.

Do you think Yamaha should take it back even though its open?

When I ordered the part, what I asked them was to order me a flywheel puller that would pull my YTM flywheel. They got me this. I phoned them today and told them it was the wrong one, they said that that is the puller they had listed for my bike.

Oh, and yea, the threads on the big part are left handed.
