Hello, I have been riding my 80cc (66cc?)motored bike 5-6 days a week for the last 4 months...I followed as many of the suggestions for the break in etc as I could and felt like I had gently brought the motor into a fully broken in state...It has performed very well for trips from 5-30 miles...I would say I have somewhere around 500 miles on it...well tonight I think my engine seized and I have no idea why...It was running very smoothly today, I rode about 20 miles in 5 mile increments...then I popped out for a quick trip to home depot and then pow! clunky engine noise follwed by stalling out..I tried restarting once, which was rough and the noise I heard made me shut it off immediately...kind of like something clunking around in the front of the engine...I rode home about 1/2 mile and took the top of the head off...there were a few salt grain sized pieces of metal in there, with maybe 5 or so simlilarly sized holes along the edge of the piston...the bike rolls with the clutch in but freezes the back wheel when the clutch is out...I took out the little pieces, replaced the top of the head and tried pedaling very fast only to have the bike skid when i let out the clutch...The piston seems to be frozen in place...I've never been able to remove the clutch plate, as the screws that came on there were of the "strip-o-matic" variety..
..I read some posts on here regarding the "woodruff key" (is that correct?) I can go and buy the drill bits to try to get them out if I need to...although I'll be walking to home depot.....can anyone help!!??!! I really hope that I don't have to replace the engine...the bike is my main, daily transportation...
