Fast_quad_03 Posted December 27, 2013 Report Share Posted December 27, 2013 I got a nice roller for christmas and put my 4 mil dune port in it, i got the jetting set about perfect but need some help. Its about 25 degrees out, the carbs are 28pwks with k&n pro flow filter with opened up airbox. It runs good while riding, but when sitting and i rev it up it takes way to long to idle down. And as it idles down it does it in 2 stages. It goes from a mild high rev for about 10 seconds to barely wanting to run at all. I havent messed with the air screw at all yet hoping to get some more knowlegeable help. Any ideas would be great. Thanks. Quote Link to comment Share on other sites More sharing options...

uman1030 Posted December 27, 2013 Report Share Posted December 27, 2013 if leakdown passed wich it sounds like it did. , richen the airscrews, but most likely your way lean on pilots and need to bump them up 1-2 sizes. what pilots are in it?
