Thanks for the info guys.. I am going to do a compression test tomorrow and I'm going to check jet, and plug

Ok so I done a compression test..... It's reading 95psi.... That's low right? Plug was a good colour tho... :-/

That's very low, 150 psi is more normal.

Ok... What would be the main cause? ...I suspect the last owner replaced piston with same size but not rebore.....

Take the top end off to check but probably rebore and new piston and rings.

Ok will do I'm guessing leisure trail is the best place to go?..... Also I think what happened was the guy that had it before me did not run in the last piston.... Sounds like it has piston slack..
