I was wondering if anyone else has had issues with 2nd gear shifting fork rod breaking on 08 or newer yz 250. The yamahas have a roll pin that holds shifting fork onto rod and it weakens rod and it breaks at roll pin (in my opinion). I just replaced this shifting fork in friends bike and after 15 min of riding it broke again. When it breaks you lose 2nd gear altogether. This bike has less than 30hrs on it from new. I did not inspect shifting drum and suppose there could be a burr or something on it causing bind and breaking. The transmission was shifting smooth though after rebuild and replacing the shifting fork.
I have searched and not found any known issues of this kind on internet. I would appreciate any feedback on this issue if others have faced it.
