You've come this far and bearings are relatively cheap.

Where did you find new shift forks?

i beg to differ there... finding all of the trans bearings for a 550 is hard enough.. and they are far from cheap.

So, the guy that sold me the bunk fork on ebay wants to make good after I emailed him with my dissatisfaction.  Here's a pic of a fork he wants to send me.  Looks damn good in comparison the others that I've had.
Let me know what you think.

That's the ticket.  You can still see the original tool marks in the machined surfaces.

Did you get pics where it rides on the drum, too?

Which 550 transmission bearings are hard to find?  Anyone know the numbers?

Here's a view of the fork where you can see the inside where it slides on drum.  Looks alright to me.

I'm so happy ;D

i have them somewhere, but after all the trouble i spent finding out what was discontinued and then sourcing them, you'll have to excuse my lack of enthusiasm for digging that up... i think i posted a bit about it in my 718 build thread. if i remember right, one of the needle bearings and one of the roller bearings were hard to find.
