2001 YZ426 - 3rd gear problem - what´s wrong????

11 posts in this topic

After a jump today my bike suddently starts to slip in 3rd gear. I felt right away, but what is wrong?

All the other gears works great, but if i put it in 3rd it pops in and out of gear. I´m thinking maybe have landed on the gearpedal and ended up bending a shift fork, is that it?

more than likely you have rounded out of broken a dog on the gear. A bent fork will normally show itself in other gears aswell. My Wr did a similar thing, but it was jumping out of fifth. The culpret was a bent fork and (which was probably caused by) a dog missing off 3rd gear (which engages fifth). Either way, it's time to split the cases for further investigation.

"It's not too difficult of a job, just follow the manual!"

and for god's sake use a torque wrench, on every bolt, and retorque the 3 screws on the CB gear. stupid screws. :thumbsup:

My YZ did the same thing but in fifth. Check the shift fork and fifth gear. The shift fork should have sharp edges on it, not rounded at all. Apparently its a common problem with the YZ. I asked Yamaha Australia about it and they said they knew nothing of it, but when I recieved my new 3rd,5th, and shift fork the new gears were 'beefed up'.

That's what I've been told.

Most of the time I'm just trying to hold on so I just back off the throttle for half a second and shift!
