We've got VB working overtime with all our 03 drama. Thanks dude:thumbsup:

I'm just going to pull the idler gear and live with the kickstart. It starts so easy anyway and I can't justify the dough just to have the button right now.

thanks champions

Here is the link to the upgrade thread



Yes, follow the instructions from this website that some of our TT members put together a while ago.

If the upgrade is done properly, then a backfire during electric starting cannot cause the woodruff key to shear. Something else may have caused the shear.
