Vic's Tip *** If you have any 6mm threads that are stripped. Install heli-coils. But if you don't have the special tap kit here is the next best thing. Just tap the striped out threads to 1/4-20 american. The tap drill for the 1/4-20 is a #7 drill. But when the 6mm pulls the threads out it's just the corect size for taping the 1/4-20. No need to drill out the old threads.

I watched the video from Timesert and have been over the website- If I were using a Chinese 2 stroke, I would seriously consider installing Timeserts from the beginning, at least at the engine mounts.
Probably put timeserts on the exhaust port too as they fail fairly often as well because of the exhaust hanging off the studs.
Unfortuneately the Timesert kit is about $50 for the 6 mm size
I've often been accused of taking an inexpensive hobby and making it an expensive one. I'd have to plead guilty to that.
I have drilled the hub and bolted the sprocket to the hub. Some have used the rag joint that comes with the kit. There is also some adapters you may use , try Live Fast Motors - Gas Motorized Bicycles and Gas Motorized Bicycle Parts for the adapter.
I would do a search for some choppers on the forum to look and get some ideals and to ask others what they have done.
