LCW Posted July 25, 2013 Report Share Posted July 25, 2013 20cc domes may be a little much for pump gas at your altitude. Most guys stick around 22cc to 23cc for pump fuel. As for a place to start on jetting 350 mains and 30 pilots with 2 turns on your screws? I'm at 2700 so... Start with fresh plugs and stay fat then jet it down till it cleans up on the top end for main jetting. Quote Link to comment Share on other sites More sharing options...
Bennett131 Posted July 29, 2013 Author Report Share Posted July 29, 2013 thanks that should help me know which jets to buy so I don't spend 100 bucks trying to get this thing right Quote Link to comment Share on other sites More sharing options...
LCW Posted July 30, 2013 Report Share Posted July 30, 2013 Be careful with those domes. You may want to test compression before running it. Had one up here at 2700 with 19cc domes that came in the shop it was melted down. Quote Link to comment Share on other sites More sharing options...
Bennett131 Posted July 31, 2013 Author Report Share Posted July 31, 2013 what psi should I be under? I was hoping for 140 or so but no more than 150 Quote Link to comment Share on other sites More sharing options...
sick421 Posted August 1, 2013 Report Share Posted August 1, 2013 350m should be a good starting point , run 27.5 pilots , 1 1/2 turns af Quote Link to comment Share on other sites More sharing options...
shakar Posted August 1, 2013 Report Share Posted August 1, 2013 20 cc domes are ok to run at sea level 91oct,even with the timing advance.anyway thats how i ran mines in the begining.but if pos run 93 if your nervous at first and keep an eye on your plugs.member you want a nice cardboard brown color on the spark bizz end. on my ported 350 in my sig i ran 27 1/2 slow jet and 330 mains and was a lil on the safe side there.ofcorse each bike is diff start high on the mains and move down jet by jet and youll got where you need to be. goodluck Quote Link to comment Share on other sites More sharing options...
Bennett131 Posted August 1, 2013 Author Report Share Posted August 1, 2013 yes im for sure going to keep an eye on my plugs 4.50 a pair is a cheap price to pay compared to a new top end lol anyways thanks for all the input I really do appreciate all the input Quote Link to comment Share on other sites More sharing options...
noonansar Posted August 4, 2013 Report Share Posted August 4, 2013 I ended up at 27.5 pilots and 330 main with a very similar setup at sea level. This may be a good starting point for you. Quote Link to comment Share on other sites More sharing options...
Stonytony Posted August 5, 2013 Report Share Posted August 5, 2013 The pods will lean you out some. Go bigger on the mains. Your pilots and needles should be fine. Cool head 22 cc dome and advanced timing won't affect jetting but pump gas may not be good due to higher heat from timing and compression. 135psi with 4+ key is what I have and I only use 110 octane. 97 banshee Elevation 400 ft Dune/drag port Coolhead 19cc 135 psi 4+ timing Vforce2 reeds Vito's fat bastard inframe pipes 320 mains Vito's needles middle clip 30 pilots 1.75 turns air screw Quote Link to comment Share on other sites More sharing options...
