Hey all, I posted about a month ago about my failed 4th gear and the headache of a time that I've had with Yamaha about it. Well, after two months of being without my bike, it's suppose to be finished this week, no thanks to Yamaha. First, I had to go to an undisclosed inside source for the gear and found out some other useful info about some tranny bearings they have changed on the 426's since their inception. Also I found out that the pin in the shift shafts are coming out since they weren't peened over enough from the factor, so you should have them tack welded. It's not a hard thing to do, but if left alone it could have a field day on your motor. Also, the clutch problems that you all are having is not a mystery and Yamaha is well aware of this. Yes, they will warranty those 50 found in a particular serial number range, but I personally know of a half dozen people that have had clutch failures, so I would venture to say there are many more than 50 out of 5000 failing. Nonetheless, I immediately upgraded to a Hinson when I heard about the first two failures. I recommend it highly. After replacing 3rd and 4th pinion gears (had to replace both since I don't trust the old 3rd gear any longer) I hope I have no other problems. After all of my heartache with this bike, I can't wait for Honda to put out a kick ass 426 beater. I'll be the first in line! Daveyg in CO.
