Yup! didnt you see the slot where it goes?

Could it have fallen out where you pulled the flywheel?

Could it be stuck to the magnet in the flywheel?

i would guess that your flywheel is just spinning around on the shaft if you didn't replace the woodruff key

I would recommend you buy a proper one ASAP, if you make one make it a temporary fix....up to you in the end though.

Before you go buying away, take it apart again, check everything is set up perfect and that nothing is missing. If the woodruff is missing then obviously your going to have to replace it... but always buy geniune Yamaha parts like this.

Go to/ring up a local yammy dealer they will sort you one out....... will be expensive mind, always is

Woodruff wont be expensive its a cheap item. Yes it will severely affect the running.
The key is only there to get the flywheel fitted in the right place (for the timing) it is NOT there to stop the flywheel spinning, the taper fit does that and when its all tightened there is no stress at all on the key / keyway. When / if you make one you need to make sure that the flywheel is on the taper properly because if tho get it wrong...ie the temporary key is too big then you will **** up your keyway damage your crank and regret you ever tried the temporary fix.

I think thats the best way if you can aford to be without your bike. But why not look for the old one, like i said on the floor of stuck inside the flywheel. If you think about it for a minute, it WAS running well before you took it off so most likely the key was fitted if you see what I mean. wink
