Keep Breaking Master links

[Ap1985]

I have an 80cc 2-stroke kit on my bicycle, when the front studs broke it twisted the original chain that came with the kit. I started searching and many people recommend #41. So I ordered number 41 chain I used a chain tool and made it the right length and went for a ride the bike seemed smoother that before.But Since I've gotten it after about 3 miles the master link breaks. Has anyone else had this issue?

you put the clip on backwards

That's my guess. Or the master link is to wide to fit between the case and cover.

Try a 420 chain much tuffer or order several links for ebay.
You might have an over compress head if it's breaking on dropping the clutch use 2 head gaskets.
Make sure your gear drive is alighn with your motor.

If you have fixed the front motor mount, you should go back to the #415 chain it was made to run with, a new one. The old chain is junk.

I tried #41 on my first build for a while, found it heavy and sloppy - without a master link.
