Where is the best place to buy good 8 mm head studs for a 67cc CG/HT engine?

Not sure what our plans are for tomorrow....I thought full threads weren't kosher - but it's got to be better than the China junk!

Pablo,
Did you use acorn nuts on your head studs? I find that these commonly damage the threads on our engines.

Yes. I AM an idiot. I just kept thinking: Someday I'm going to get some nice 8mm nuts....

Now I will!

No, you aren't. I also learned the hard way about acorn nuts and many other issues that can go (doesn't mean they will) wrong with our chinese 2 stroke kits.

Here is a tip that is risky to fix your bike without having to buy new studs. If you have a thread die, clean the stripped thread out with the die and then install the stud reversed but definitely JB weld the stud on the bottom. Reversed install means damaged thread are screwed/jb welded into block. A cheap quick fix to get you back on the road but I would understand perfectly if you wanted new studs.
