Cylinder head bolt - thread repair

[Walle]

83 GSX750esd

I have a question about a stripped threads on my bike. The previous owner apparently over tightened one of those wide headed bolts on the cylinder head cover with an o-ring beneath. The threads are totally gone.

Looking in the manual I see that these bolts attach to the cam shaft holders. I understand that these "holders" cant be replaced as they are are machined to fit with the rest of the engine block.

What would you recommend I do? I'm thinking go up 1 size on the thread if I can get the bolt that fits.

thank you



Maybe this is bad form, but I have a bonus question The bike wont rev above 8000 rpm. I am doing all kinds of maintenance over this winter, so hopefully the problem wont be there next season.
I am just curious to your thoughts.

So far I have installed a new air filter, and a new fuelcock. Next on my list are carb cleaning and valve adjustment and carb balancing.

The bike has stock airbox and 4-1 exhaust

regarding your stripped hole. I don't think you will find that screw with the next larger thread size, so your best bet would be a heli-coil or similar!! Also get a NEW screw as the threads are probably messed up too.

I bet if you clean your carbs and do the valve check, next spring your bike will rev freely to redline and beyond....

Helicoil or solid insert. This is a very common problem and easily fixable. Use a drill press to drill the hole for the insert so it goes in straight straight.
