purpleTHRILLS Posted February 13, 2014 Report Share Posted February 13, 2014 I've got stock carbs, vforce 4s , fast cool head with 20cc domes, fmf fatty gold, at 1900 ft above sea level and an average of 20-30 Celsius. What would be the best jetting set up for what I have. Also are the fatties good for the rest of my setup or do you guys recomend different pipes that will give me better low mid power Quote Link to comment Share on other sites More sharing options...
kedge82 Posted February 16, 2014 Report Share Posted February 16, 2014 im not a 100% sure if domes require an increase in jets i know 20 cc domes is really close to race fuel. at 1900 ft with 20 30 c witch i think is 80 to a 100 degrees i would think you need to be around 310 on your main. and prolly 30 on your pilot jets. 27.5 would be good but the vf4s require a lil more fuel. best bet is to start at 340 work down to best preformance. dont take other ppls word on your jettting there just recamendations.
