Hi.

Total newb question so I apologise in advance.

I just tried to change the engine sprocket on my Rotax FR125 for the first time but am having real difficulty.
I'm changing from a 12 to a 13t but cant get the old one off the clutch drum? What are you supposed to do? Do you need the special tool? How is this used and where do I get it from?

What's with the little pin in the replacement sprocket? I don't see how you can get this is?

I tried taking the nut off the back of the sprocket with a 38mm socket but this wasn't going to happen under any circumstances.

Is it best to have a couple of sprocket and clutch drum complete assemblies so I don't have to do this again? Are new clutch drums cheap?

Forgive my ignorance.
