    Heli-coiling reed screw holes?

    So I just did a pressure check on the block of my sl900 and everything looks good EXCEPT the top area of th emiddle reed cage, which is loose because the two mounting bolts on top of that particular reed cage are stripped badly. Any suggestions? I was wondering about heli-coiling but I have never done it, the concept seems straight forward though. Would I just drill the hole a bit bigger and then get a tap and thread in the coil so that the screw can thread into the coil, or and I oversimplifying haha.

    The heli-coil kit uses a special tap that comes with the kit.Then you'll normally have to buy a drill bit that is a not normal drill size that's in you general size drill set. (Should be able to get them at ace or aco),Then just drill and tap,Run the heli-coil in with the tool provided and your done. McMaster Carr sells them and also a soild key locking threaded insert style one that uses a common tap.(This may be better then the Heli-coil sinceIt maybe least likely to allow air to seap buy)

    Be sure to keep all the metal chaf during drilling, tapping, and inserting the coil, out of the crankcase.

    Some grease on your drill bit will catch the bits and shavings while you drill.

    I suggest using an insert versus a heli-coil.

    I agree! and don't forget to use red loctite on the insert.

    thanks for the advice!

    I also remembered this would be an opportune time to do the bolt that broke off on the jetpump of my slx (it has only 3 of the long bolts holding it together at the moment). I'm assuming I would just drill all the crap out of there and do the same thing! No amount of WD-40 is getting that piece of bolt out haha. Anybody have an extra extended pump bolt they would like to part with?
