Title: Jetting 44s for 2109cc Post by: RUSS74GHIA on August 23, 2014, 16:25:01 pm Hi,
I'm just about to go up to 44x37 Street Eliminators and 44HPMXs from 40x35.5 043s and 40DRLAs I want to get a ballpark set-up on the carbs before I get it to the dyno. The rest of the spec is; 76x94 fully balanced and match-weighted W125 1.25:1 9.5:1 Track use only. I thought about the following from looking at other people specs: 38mm venturis 155 mains f11 or f15 tubes 200 airs Would that be roundabout the right set-up?
