I have 97 elite and I am looking to get some higher top end speed. I want to remove the clutch outer pulley plate. I many years ago drilled out the header exhaust after the dealer told me about it. I have the crankcase cover off. but i need to remove the nut. I don't have an impact wrench or a universal holder to hold the flywheel. What is a poor man's way of doing this? In the picture below is this the correct starter drive gear I need to remove to get to the clutch plate?

Thanks

an impact is a must. you dont need a flywheel holder or anything. you can hold it with your hand.

Tightening

Can't get any poorer than this!
I would bang the ratchet with an extension rather than just turn it as it puts less stress on the bolt holding the wrench.

If i had to take my crankcase off many times I think I would build one of those as well. Since, I have a full machine shop at my disposable if need be. the later pictures are sweet little device.

I am sure there is a impact wrench in there somewhere. But mainly it is a machine shop. I know main machine shops that don't have impact wrenchs since they just have mills, cnc's, lathes(sp), etc like the shop I have access to. But, the main reason I wanted a cheap way was the moped is located at my house and not the shop. So I don't have an air line at my house which is what the impact wrench would have been. Also, I rather work on the moped at home then a place I spend 70 hours a week.

Hope you can understand that.
