I Have recently become the proud owner of a xr600r 1997 model. i recently had to go up from the 94mm piston to a wiseco 98mm piston due to a piston ring that popped out and did some damage to the barrel. At the same time i have replaced valves, timing chain etc and made sure that everything is up to spec. Since the rebuild i have not been able to kick start it at all, but runs after a push start, but idle is inconsistent. To me it feels like it is very rich, as there is alot of smoke out the exhaust.
I would love any help on how to tune the carb, so she will kick start again, Push starting is a bit of a ball ache.
What would be the correct jetting size considering i am at sea level, would the standard jets be able to work? Bike also has a boson Slip on. How much will that affect things? I Also have a no lights issue at the moment, but need to get here starting before i can work on that. Please any advice would be amazingly helpful. Thank you in advance, and happy riding
