Default Re: Some help with centrifugal clutch install

Exactly, but don't make the new groove too deep. You don't want to allow the woodruff key to be able to move up and out of the notch in the crankshaft.
Also, you can make it as long as you want to, but making it full length of the clutch hub is creating more work for yourself than necessary.
When you get close to being finished with the groove, cut a little at a time and check the fitment frequently until you get a perfect fit. Sneak up to perfection rather than trying to do it all in one cutting session.
