Late last season I wasn't riding often and when I fired it up after a long time and under cold storing conditions it didn't fire up right away, more like 40 kicks later. I thought it was just cold but I discovered the bolt holding the kickstart lever was loose. I tightened it and the compression felt like it was normal like always. I went to fire it up for the first time and the kickstart is tight but it feels like low compression so I'm not sure if I stripped something or the topend is shot. Im not a mechanic by any means but I'm concerned. Any advice?
