brokenzipper Posted September 18, 2008 Report Share Posted September 18, 2008 Hey guys, I'm curious on your opinions of what the best size/brand of carbs would be for a nice banshee with mild porting, T5's, cool head w/ 20cc domes. 66.25mm pistons. I purchased a Cascade Innovations 2 into 1 carb setup (pwk35, 200 main, 50 pilot, EEJ needle on 4th clip, a/f screw 1 1/2 turns out) last summer but haven't had the best of luck with it. It seems to be constantly lean. Which is what I've read can often be the case with this setup. I bought my shee with dual pwk35 air striker carbs (unsure of the specifics) and running a boost bottle. I've heard that boost bottles are crap too... So what would be the optimum size carbs to go back to a dual carb setup if always riding the dunes? I appreciate your responses...

Wildcardracing Posted September 18, 2008 Report Share Posted September 18, 2008 Mild porting/T-5's, I'd have stayed with the stockers to be honest. No bigger than a set of 33's. You may have some luck trading your 35's for some smaller carbs. Quote Link to comment Share on other sites More sharing options...
IrideA250R Posted September 18, 2008 Report Share Posted September 18, 2008 I run 28mm PWKs, they are awesome. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted September 18, 2008 Report Share Posted September 18, 2008 I would go with dual PWK 33's. You could probably sell your 2-1 for the price of the two carbs. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted September 18, 2008 Report Share Posted September 18, 2008 I recommend 28's, but wouldn't go bigger than 30's. Quote Link to comment Share on other sites More sharing options...
4stroker Posted September 18, 2008 Report Share Posted September 18, 2008 It seems to be constantly lean. ive never ran a 2-1 setup but i believe the cause of that is the fuel level in the float bowl is lower than it is in a dual setup, because now you only have one bowl supplying fuel to the engine. you have to set your float higher or run a bigger billet bowl. also i would run dual 33s for duning.

Thats not it. That jetting looks very rich. I dont recommend the 2 into 1 for sand dunes, so I would switch to twin carbs anyway. Quote Link to comment Share on other sites More sharing options...
