Hello,
I recently got a 2 stroke 80cc gas bike kit off eBay and mounted it to my bike. Despite a lot of issues and frustrations at first (this is my first time doing this kind of stuff!) I managed to get everything working decently, and the bike has about 40 miles on it so far.
The issue I’m having started when I was first assembling the kit. The muffler screws just wouldn’t tighten enough with a hex wrench (I don’t have an impact driver). I tightened them as much as I could, but there was still a good centimeter or so between the locking washers and the muffler base. I just can’t tighten them anymore with a hex wrench because I’ll probably strip the head (would be a disaster!). So I tried using more washers and some superglue, which worked until yesterday when I noticed that the engine became super loud and started acting up (lack of back pressure I guess). The exhaust muffler screws had loosened themselves again. I came up with two solutions (could combine both of them):
1. Use some proper high-temperature thread locker (superglue probably melted)
2. Buy some M6 - 1.0 x 25 bolts instead of screws (bolts won’t strip and are easy to tighten really well)
Any suggestions or comments on what I should do would be greatly appreciated. Thanks!
