I have an '85 200x thats getting a new wiseco piston (10.25:1) and getting a new set of stock sized valves. With a k&n and a cobra exhaust, should I run a main jet bigger than stock (108). When I rebuilt the carb i replaced a 110 that had been in there with a 108 that came with the kit. I figured that the 200x was running kinda crappy due to that jet but now after inspecting the motor internals that i could have been loss of compression on the piston rings and valves being very worn. Jetting recommendations on this application are highly welcome!
