Ak_grizzly Posted May 28, 2013 Report Share Posted May 28, 2013 I have a 4mil sand ported motor with FMF gold series pipes, K&N pods, Coolhead with 22cc domes, vforce 3 reeds with 36mm Kehim Carbs and +4 on the timing plate. My problem is in first gear it bogs from no throttle all the way to 1/2 throttle then it pulls good to redline from 1/2 to Full throttle. I pulled the carbs and found the Pilot Jet was 50 and the Main jets were 150. I bought the carbs on Banshehq and I am not sure if these are the right size jets for my setup. Any recommendations? I filled out the Jetting FAQ below. 1) What type of aftermarket exhaust do you have?....... FMF gold series 2) What type of airfilter do you have?....K & N Pod 3) Are you a)running a stock airbox with lid stock airbox with NO lid c) Stock airbox with vents d) no airbox at all..No airbox 4) What is your elevation? (If you don't know, go here: http://www.topozone.com )....120 feet 5) What size pilot jets are you using?....50 6) What size main jets are you using?....150 7) What temperature is your Banshee jetted for?....don't know 8) Do you have a port job? yes...by custom sandz 9) What kind of carbs?..... Keihim 10) What size carbs?....36mm Quote Link to comment Share on other sites More sharing options...

Oregon dunner Posted May 29, 2013 Report Share Posted May 29, 2013 Try going down on your pilot. I have a ported 4mil 421 cub with 35pwk.152 on the main jet, cel on 4th clip from the top and a 45 pilot jet. I have 19 cc domes,VF3 reeds +7, CPI inframes. I ride at sea level.

rjdgriff Posted May 29, 2013 Report Share Posted May 29, 2013 There is a jetting thread on here someplace i think it's titled what jets are you using that has all the info you could ask for on jetting. You might try and find that thread, it will be helpful Quote Link to comment Share on other sites More sharing options...

BUILDER Posted May 30, 2013 Report Share Posted May 30, 2013 They are 34mm PJ carbs (he bought them from me) the jetting should be pretty close I would try going up or down one size on the pilot first and see what that does. If you go up and it is worse then go down 2 sizes and see if it gets better. Get the bottom end right then you can play with the main and make sure it is right also.

Oregon dunner Posted June 2, 2013 Report Share Posted June 2, 2013 Looks a tad rich. Some people like to run a little bit richer to be on the safe. I like to be right on so I can get the most out of my motor. Just my opinion tho. Quote Link to comment Share on other sites More sharing options...
