2k7cheeta Posted February 1, 2021 Report Share Posted February 1, 2021 Driveline 421 assassin , 34mm mikuni, k&n pods, vf4, sea level. Where should I start with jetting? The carbs have 270 main and 30 pilots now and came off a stock cylinder stroker. I know neither is ideal but pro circuit or t5s? I have t5s now and my buddy said he’d strait trade for the pro circuits. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted February 7, 2021 Report Share Posted February 7, 2021 That jetting is probably pretty close. Try it first and see how it runs. Quote Link to comment Share on other sites More sharing options...
