I have a "99 trinity 440EX (full kit, over $2000 in receipts) which has worked very well for me over the last two years. The guy i bought it from was using the stock 35.5 mm carb with a 185 jet. I have spoken to trinity and they claim that is the best carb to use with their kit. It seems like it would be a good idea to use a bigger carb with this potent engine. Right now at competition hill at Dumont I beat Polaris 500's and Raptors with minor work on a regular basis and I stay close to DS 650's with minor work. I ride mostly track and some dunes. Should I expect any performance gains with a larger carb? Will there be any negative effect on the reliability of the engine? What carb would you recommend?

Thanks in advance!!

well im running the 465 and had a stock carb, but the tech guys at trinity told me you dont have to but it would help to upgrade. Im running a 41mm fcr.
