Today: broken thread for the inlet manifold: Use to be M6, hole was around 10mm :(.
I used an epoxy cement, a new screw with grinded head, the manifold to guide the screw (not tighten yet)....
Dead end thread are not easy to repair without a machine shop :oops:

I actually like JB Weld for some uses, however, I cannot imagine it holding up for very long with the heat and vibration it is exposed to in that application.

Test with gas today, gears are changing well....
I will not do more tests, I am starting to rebuilt the new old frame.
I will use the engine as it is, could be a second project went I will have the registration done.

I did a few repairs with such epoxy without issues. This bike will never do long trips :scooter:, I have no risks :)

I am starting to remove all parts from the old frame...
I will keep the front fork, to be closer as the original type, easier for the registration later (I have no title)...
I will cut the original headlight support and use a new support...

That crack in that head is an indication that the timing chain was slapping inside the head. Folks would ride those bikes like the old two stroke bikes and stretch the timing chains until they wouldn't run anymore. More parts and more money to fix those problems.
