bearing
I pulled my cover off and found the bearing cage out with two balls left in it. Guess I was a little late but no harm to the shaft. Couldn't get a grip on the remaining part of the race so I scored across it with a cut off wheel in the dremel. One tap with a chisel and it split and slid right off. Its a cheap Russian bearing, cut real easy. $38? from the dealer, I used the same bearing as behind the driven clutch only from my local bearing place. It doesn't have the grease holes but its sealed and that's what the Pro's use now also. Part number on the bag for a Koyo was 6205SEE $11
Warm the new bearing up and have the appropreate size pipe-socket to drive it on. I used a bolt (mine was metric 09 155) and washer to add tension, then tap on, repeat. Remember your chain case is attached on the other end.
