Broken Bolts 97 GSX

[pthompson7]

Hey Guys. I had this problem earlier. I found a bolt that must have been a mounting bolt. It a rear bolt on the (drivers) left side, under where the exhaust runs. I replaced the bolt and tightened up all the exhaust bolts and also replaced the other bolt that vibrated out, on the exhaust assembly pipe. That one actually cracked. (I had it welded where the bolt goes through it with pure tungsten) I put it all back together and ran for about a half hour. When we first started the RPS were good and it ran pretty good. After about a half hour the RPS started dropping and I found another bolt in the bottom of the craft. What are the primary causes of the vibration? Should I pull off the imeller and have a loof at it to see what it looks like? I would appreciate any advice you are willing to give.

Thanks,
Pete

check the driveshaft to make sure it is not bent and checkout the motormounts.

How would I be able to tell if the drive shaft is broken? One of the mount bolts if out again as well. So what I cant figure out is what is causing the vibration. I'm not sure what to look for in the drive shaft, or what would cause the drive shaft to get bent? Can you explaine a little more.

Not your everyday mechanic here.
