Can someone help me out with this one?
Back in April I broke my counter shaft on my bike. I tore down the motor to fix it, got it all back together, and everything was perfect. Until this last weekend, I was up riding today, and the bike stalled half way through the ride, so I went to start it, and the kick starter went down but didn't catch, so I tried it again, nothing so I pushed it up a hill to bump start it. Got it running everything was good or so I thought. I didn't hear any out of the normal noises, but there was something I couldn't put my finger on. I was about half way back to the truck and decided to stop and wait until my girlfriend came back with the truck. Well I get home and start to tear into it to see what is wrong with it, I figured I will remove the clutch basket to see in there instead of tearing it all apart, and sure enough, I broke the counter shaft in the exact same place as I did back in April. So now I have to tear it all apart to replace that damn shaft.
My question is, might anyone know why it keeps breaking? Last time someone suggested that it might be because I might have had my chain alittle too tight. This time I know it shouldn't have been the problem, but might there be some other explination for this.
The end of the shaft broke off in the bearing on the right side of the case, where the gear attaches, which mates up with the gear on the back of the clutch basket and the kick starter gear.
I'm kinda thinking that it might be a bad bearing, but everyone I have talked to has never heard of such a problem.
Forgot to mention my bike is a 98 XR400
