I have a 93 TRX200 Type2 that has oil leaking from the lower sproket cover bolt. Not sure what is causing it but was told it could be from the left crankcase gasket so I was going to try and attempt to change it and see if I could see any other issues that might be causing the problem. My question is, can I take the left side crankcase cover off and replace the gasket with the motor in place? I've never torn into the ATV but the manual does't make this look like too big of a job so I thought I would give it a whirl. Any advice would be GREATLY appreciated..
