Any Suggestions?

[miller]

Today when I got done riding I was looking over my engine and tightening any bolts that were a bit loose and the top bolt on my crankcase was loose and come to find out it is stripped. So to see if a different one worked I took one from another part on the crankcase and this one wouldnt tighten either because everything inside is stripped. Im not going to ride it without this bolt missing, should I go to the hardware store and try to find a bolt a touch bigger and try to wrench it in? By the way my ski is a 650sx and the engine is about a year old, remanufactured.
Any suggestions on what to do?
thanks

Remanufactured by whom?

I am not sure, my local shop got it for me, somewhere out west I know that much because it took forever to get. For what it is worth, MATT

I suppose a timecert might do the trick, along with a corresponding bolt (If the threads in the case are shot)

Can you describe a little more which bolt you are referring to? On Yamaha's all of the case bolts go in through the bottom, I think. The key ones to worry about are the 8 center section ones that hold the crank in.

Do you perhaps mean the motor mount bolts or head bolts?

Throwing a 'slightly larger' screw in may cause you to cross thread it and get it stuck, then you are in for more work. How about tapping it with a helicoil tap and throwing a helicoil in. Then you can use the correct screw.

here we go.....I hope this works. The link below shows the part of the engine where the bolt was messed up. It is the bolt just to the right of the brake breather, on the engine cover (bottom engine cover plate the bolt just to the right of the black circle).
