stock flywheel woodruff key size?

[BigMatt]

could any one tell me the size or specs maybe even measure the stock woodruff key with a mic, I'm getting a timing plate and want to advance but I'm not sure if the guy i bought it from used the cheap key and if its already advanced. also I had one hell of a time pulling the flywheel could I use a little anti-seize of the out put shaft? thanks

As far as I know the key is only available from Yamaha unless you have an advance key. It is easy to tell an advance key- the top half is offset from the bottom half. If there is any kind of a step on it, it is either an advance key or a wore out stock key, either way it needs to be replaced. I would not use any anti-sieze on the crank, you want that flywheel to be stuck in place good so it does not loosen up. When it is time to remove it, install the puller corectly and then tighten the screw until there is pressure on it. Then smack the end of the pressure screw with a hammer and the flywheel will pop right off.

I just order half a dozen keys from bike bandit. I have also made my own out of a standard key. Bought one that was too big all around and just ground it down until it fit.

also how do i know its set all the way in, is there a torque setting. i think i have a stock key, it does not have any groves or steps.
