I am trying to get the proper jetting on my Predator and am wondering who makes the factory carb for this bike. I am running a 180 jet and its still too lean. How much larger can I get. I have my lows and mids but top end is still cutting out. Just a list of what I have done to the bike: Full Exhaust system DMC Afterburner Competition, Replaced the Factory intake with a big bore tube and K&N cone filter, Installed a Dynatek FS Ignition System. Installed a Procom Ignition Rectifier.
