GYTR flywheel

A little tricky to put on but here's a trick I used. It's tough without a tool to hold the flywheel from spinning, but there's another option. After the cover is off the flywheel (left side) get it in 5th gear. Slide a peice of wood in between spokes of rear wheel ABOVE the swingarm so when you loosen the nut the motor won't turn. I used a survey stake, but another peice of wood will work. It didn't damage the spokes and allowed me to loosen the flywheel nut easily. Use your flywheel puller to get the stocker off (it screws in with reverse threads). Then tighten the outer bolt of flywheel puller with a socket (righty tighty). THe flywheel will pop off pretty easily. Slide new one on, add washer and nut and tighten. You'll need to put the wood stake through the spokes again BELOW the swingarm this time as you are tightening in the opposite direction. Don't use a steel bar or anything hard or you could damage spokes. Put your cover back on and you're done!

A: The GYTR Flywheel fits within the space of the OEM ignition cover only. Just like the Stealy Flywheel Weight, it will not clear under an aftermarket cover. You would still need a cover spacer to use this flywheel weight under a Boyesen or Pro Circuit Ignition Cover.

Stealthy 9 oz flywheel requires a spacer to work with aftermarket ignition covers, does this product requite that as well?

A: This flywheel weight should work fine with the OEM cover on your 2008 Yamaha YZ250. It shouldn't require any type of aftermarket cover.
