ride99 Posted February 7, 2013 Report Posted February 7, 2013 I have a a 4mill bored to 65mm, stock carbs, vforce2 reeds, cool head 22cc domes, F.A.S.T. dune/play port, airbox no lid with k&n proflow, t5 pipes. I am about 800ft above sea level and its about 10-30 degrees out. I need a good starting point for my jetting. Thanks in advance! Quote
bluebanshee98 Posted February 7, 2013 Report Posted February 7, 2013 27.5 pilots,and since its cold as a mother out i would put 360 mains in. better safe then sorry. my 4 mil dune ported bike with shearers, stock carbs and pods ran mint with 27.5 pilots, mid clip on stock needle, and 340 mains at 85 degrees out. plug chop on the 340 mains at 85 outside was perfect. best bet will be to call jeff at fast since he did the porting but it should be pretty similar jetting wise to what i said. a plug chop will be your best bet and will give you a idea if you have air leaks or not. if its lean with 360s you have a bad air leak. learn to also use the search function on the site Quote
