well decided to change all bearings since i have all torn apart took the chain case off was not to happy about taking the park brake all apart to remove chain case but did it anyway ,removed the air box and removed the remaining bearing on the top shaft im up to 150 in bearings and oil seals yami parts dont come cheap,did find some deep gouges in the chain case but didn`t go all the way through gave it to a friend of mine to take to his work were he has some industrial cleaner will decide what to do from there,and also found a second hand chain wictch sells for 225 canadian 75 foe the used on will inspect gears when all parts are here,well hope everything goes back together as smoothly as it came apart will keep you posted hope to have it back together for the weekend.

grease your new yamaha bearings. If you crack the seal on a new one you will notice 1 buger of grease in the entire thing. its ridiculous
 
Chain was $90 last time I bought one. You can buy higher quality bearing at a bearing place for much less than oem. Most will know what you need but if you look within the yamaha part number you'll see the bearing type (6205...).
 
As long as you have jackshaft out, take it in and have it checked to make sure it is straight. Yamaha does a great job of fit and finish but, the jack and drive shafts are typically not as straight as they could be. This leads to premature bearing failure and vibration while riding. The cost is usually minimum but the gain is a smoother ride and less bearing fatigue.
 
Just did the same thing to mine...Yamaha bearings are way to expensive!!!! I went to a local guy who sell every kind or bearing on earth and got mine some exact thing for $25...Even if those go out again you still don't have as much money in them...If Yamaha's bearings were so great then why did thy FAIL??? I mean their's a million resons why a bearing will fail but, it seems like it happens alot...
