marmenta Posted November 6, 2014 Report Posted November 6, 2014 Currently running a 4mil with a single carb (2 into 1). It has a PJ on it with a 184 main jet. Clip is on the second to richest. Carb leaks horribly and I think I can get more out of this motor. I am thinking of switching to a 38mm PWK. Is this a good idea? What size main jet should I use? Quote
marmenta Posted November 6, 2014 Author Report Posted November 6, 2014 go back to dual carbs if I went back to dual carbs should I run the PWK 38's? Where should I start with jetting? Quote
BUILDER Posted November 6, 2014 Report Posted November 6, 2014 4 Mill stock cylinder or cub? Go back to stock carbs either way but unless you have a large motor you will be just fine with 35 carbs Quote
marmenta Posted November 6, 2014 Author Report Posted November 6, 2014 4 Mill stock cylinder or cub? Go back to stock carbs either way but unless you have a large motor you will be just fine with 35 carbs 4 mill stock cylinders with a cool head. It has been ported but I have no idea what type of job was done. I bought the cylinders years ago from some guy parting out a bike. Compressions is 165. I run 110 octane. t-6 pipes What would be the advantages to going back to two carbs? Should I go with the PWK airstrykers? or just a standard PWK? Whats the difference between the two? Quote
BUILDER Posted November 6, 2014 Report Posted November 6, 2014 Go with standard PWK carbs. Your bike will run better from top to bottom as far as I am concerned. Quote
marmenta Posted November 10, 2014 Author Report Posted November 10, 2014 Also shit can those t6 pipes really? why? Quote
dave5.0 Posted November 10, 2014 Report Posted November 10, 2014 Well I guess if your running a 2into1 your not concerned about top end on this beast. Is it a ported 4 mill or is it one of those spacer plate racers? Quote

Is it a ported 4 mill or is it one of those spacer plate racers? It is just a dune bike. I rarely drag race. The mid and low end are amazing and it still holds its own if I do want to drag. It has been ported and is not "spacer plate racer". haha a PWK38 would be around a 160-170 main and a 65 pilot. thank you very much. this is exactly what I needed. A buddy of mine has a set I am going to try. Quote
