slobanshee Posted February 9, 2015 Report Posted February 9, 2015 Getting close to finishing up my 421 serval built from extra parts I had laying around....so kinda a collection of crap. Ha. Wanted to get a good starting point on jetting. 4 mil serval with F.A.S.T. cleanup, 24cc domes, 145ish psi, vf3 reeds, stock carbs, pod filters, and T5s at 900ish feet above sea level. Was thinking somewhere along the lines of 30 pilot and 340 main maybe? Thanks!!! Quote
dirtydownunder Posted February 9, 2015 Report Posted February 9, 2015 Yeh mate sounds about right. Not sure on your temps but when i had stock port 421 serval with t5 24cc and stock carbs, i ran 340/27.5 pilot. At 70f temps. And was a touch rich but ran great. 1 Quote
