Something I never got around to doing though, since my Briggs blew up, is I was gonna helicoil the exhaust port threads for 1/4-20. On my block there was just barely enough room. I had stripped the threads out on at least one bolt.

That bike looks good in white.
For the situation I wanted to use Heli Coil, but not enough material I did with just a bolt and nut through ruined threaded hole. Not always is this possible if there is not a threaded through hole where a nut can be opposite side. In the case of a few of the crankcase cover bolts on my Briggs I did this and it looks a little funny, but holds perfect. The used of Alumaweld or whatever with a torch maybe could add material and then re-thread, but I would need practice first with a hot enough torch I do not have yet for that stuff.

This bike was posted under search 'custom built bicycles'. Just might give it another go at building a rear suspension. Totally adaptable to a bike frame.

Many years ago 1905 i think there was a bike built just like that, of cores antique. But the same principle, same style fork. With a pivot back there you need chain pensioners, like this one has....KOOL.............Curt
