ok fresh start on my 421

[steven]

ok starting fresh again on my jetting. I would like to know a good starting point for my jetting. The mods I got are a 421 cheetah cub with cool head and 22cc domes. I also have 35mm pwk with 6inch pods and pre filters. I have T5 pipes and stoke reeds. I got no more money left for some vf3 but I wish I did. I currently have it running on C12 VP race fuel. Oh and +4 timing. Thats all. So if someone can help me out with a good starting point on a rich side of jetting would be greatly appreciated. Thanks!! Oh almost forgot I ride at sea level.

with little or no porting,i would run 165 mains, 52 pilots and cel needles on the middle clip.but depends how far you are from sea level!

I'd say start at 162, might need to come down to a 158. CEL needle as well with 48 or 50 pilot.

 

I run a 155 main 48 pilot and CEL needle and I'm around 1000 ft.
