Blacksmith Posted November 15, 2003 Report Share Posted November 15, 2003 Guys, I just got my hands on a Trinity 2to1 carb setup with a 35mm Keihin carb. I am wondering where to start out with my jetting. I tried to ask Trinity, but when they did not ask about elevation or mods, I know they did not care about giving me any good info. Anyway, I am running a mostly stock motor. Shaved head, Boyson two stage reeds on stock cages, FMF pipes, PD Foam filter on a proflow and not air box lid. I am currently running stock size carbs with 27.5 pilots and 280 mains. My elevation is 3000 feet, and I have about 140 lbs of compression. Anyone got any ideas where I should start with this new setup. I would really like to get it to work without spending $50 on jets. Thanks.

evil Posted November 15, 2003 Report Share Posted November 15, 2003 somewhere in the 48 pilot and 168 main range, that would be a good start anyway Quote Link to comment Share on other sites More sharing options...
dirtbike killer Posted November 15, 2003 Report Share Posted November 15, 2003 I had a 30 pilot and 320 mains, and with the cv I run 48 pilot and 175 main. Evil's suggustion sounds right on the money for a good start point for you. Quote Link to comment Share on other sites More sharing options...
Leadfoot350 Posted November 16, 2003 Report Share Posted November 16, 2003 Look on trinitys web site trinityracing.com under the tech section and they will give you a ruff estimate on what to use. I think it is a 48 and 175 also. MAKE SURE that you are using NEW STRONG reeds that work good either that the 2-1 will suck big time. I would suggest that you should get some boyson reeds or v-force reeds. Quote Link to comment Share on other sites More sharing options...
