250-500cc question on steahly flywheel install on WR

I am installing a Steahly flywheel weight on my 07 WR250. I bought the bike used and the weight came with it. No instructions were included. I removed the nut and washer that hold the stock flywheel on using an air wrench. I screwed the weight on until it fit flush on there. I tightened down the four set screws that secure it to the flywheel. The weight screws into the stock flywheel threads.Since I can't use the stock nut and washer, how does the flywheel keep from unscrewing itself from the shaft? I am afraid to start it before I find the answer to this question!

The weight needs to be torqued down like the stock nut. It has became your fly wheel nut.

Loosen the four set screws and torque it down using the ratchet tool that comes with the FWW. Then tighten the 4 set screws.

If you don't have that tool, don't ride it until you get one and torque the weight down to spec..

Thanks. I don't have one but will get one.

Me too, because I want to install one on my WR250 2010... too nervous for my technical riding here in Spain!!

Thanks

I put one on my '06. A really effective fix for that nervous feeling in the technical or snotty stuff. For $100, you can't beat it.

I also put a G2 throttle on. It helps too.

With both together, you get really good traction control.
