Yamaha vino 50cc 2t wont crank  By  luke0000 (Read 90 times)

So I recently I did a big bore kit, put a new exhaust all that and it won’t crank. The bike didn’t start before unless I would manually choke out the air box. So I did more investigating on the bike. There is a good spark and timing seems right, when the spark plug is in the bike it will usually crank about once and then would start a crunching or clicking of gear sort of noise. When the plug was out it sounded like the bike was cranking over very well no clicking of gears. I was looking at other forums and people say that the starter could be bad? When I try to kick start it there is good compression but would not fire after multiple attempts. The batteries are all good I have about 12.8v. Maybe I’m doing something wrong idk I’m no mechanic lol

Thx
