Could be that your oil pump needs to be adjusted......sounds like it's running a bit rich :headscratch: ........that's assuming of course, that you're NOT running pre-mix. ;)

BTW..... :welcome: to the Forum

Sounds more like a loss of compression due to a faulty plug thread.

Oil shouldn't leak out of that hole.

Take a good look at the thread that the plug screws into. Maybe a previous owner has over tightened the plug at some point and stripped the thread.

Double check the main fuse. That box is part of the stop circuit and relies on a good 12v supply to energise the solinoid inside it. The bike should still run without the battery though so you may have to look else where.
