Do you know for sure what jets are in it now?Only reason I ask is if you bought the quad used ya never know whats been done.

A tight leak free motor, nice spark, and proper fuel air mixture the. Learning to tune the carbie takes a few tries to get it. But the down side is get it wrong and it's melt down. A key piece of equipment is your nose. You can smell when the mill is burning lean. The ear too. If the pilot is real lean and you go from WFO to nuttin and you don't here the ding ding ding, there is not much gas in there. The carbie is easy to get the hang of and once you learn how to tune it 20 seconds seconds of tuning before you ride and it'll friggin rip for ya. There are some good carb tuning manuals. Read up and ask some questions. Focus on the pilot and main jets.
