Thanks in advance for any help.
I was bombing along on my 80cc 2 Stroke bicycle conversion & the rear wheel locked up. Restarted and it happened again. I could tell she was not happy.
Thought it was a seized piston but with my limited knowledge I felt problem was in the clutch/gear area as motor would start easy after a while without requiring me to free piston. And locking would happen after engaging drive.
Upon inspecting Clutch Drive Gear Nut

I can see that it is damaged with a tooth missing and some scaring upon the clutch wheel cog. When I tighten the Drive Nut the bike will run a short distance then will become loose losing drive and rattling.
So my question is - is it a big problem. Would replacing the nut be of help or is the problem of greater magnitude - I bow to your expertise.
Background - I have had bike about a year. I ran in carefully. For the past 4 months I have ridden 3 times a week 10 km twice a day on fairy bouncy surface (Irish roads) I go through a speed camera and it flashes me at 60 kph (that's my girl) and I go 50-55 kph all journey. I always put plenty of oil in mix and the heat is not an issue ! I weight 240 pound (I think, I'm not sure US Measures) - maybe that's an issue with the drive gear and its just worn out (I don't need anybody to tell me to give up the pork pies - ok)
Thanks again
