Just replaced the carb on my 07 with a 2014 carb since my old carb was beaten up and a lot of the jets were broken in the mid-carb. Re-jetted the quad 185-main jet and a 48-pilot jet with a 55-leak jet and I'm at 2.5 turns out on the AFR. My current mods are DASA with air box lid off with K&N filter and looks to be a ported head as well. Quad runs excellent until you hit WOT at the top of the RPMs it sputters and cuts out. Other than that it ran excellent and to top it off when loading it up the rear grab bar broke off so I guess I will replace that and fix the rear tail light harness and get a new tail light.
