well i broke off 3 bolts on the force 125 exhaust cover, which needed to be taken off to clean out the corrosion.....i got all 3 of them drilled out and i was going to try to go back with the same thread size...but i still have some steel threads left in the housing threads which makes going back with original size almost impossible with breaking some taps off in it....so i decided i need to put heli-coils in them...is there a chart or something that can tell me what is size bit/tap and heli-coil to use? i've installed some heli-coils at work a very long time ago just cant remember the specifics on them.
