i just bought a used 35 pwk with a 2 into 1 intake . it is not a trinity intake , it is a dual tube about 4 inches long . i am getting huge amount of bog on low end and will not idle , lot of white smoke out of the pipes. i just put this on and have not started to adjust anything yet. i need some thoughts and opinions on what the problem is. it has a 50 pilot and 158 main i don't know what the needle is set at , i have not figured how to check that yet. the air screw is at 2.5 turns out. my mods are cool head 18 domes 181 compression , pro circuit pipes, fmf torque reeds, adjustable stator at 5 degrees, bored .40 over, open air box, 32:1 mix with vp red 104 fuel . this bike is a fully prepared mx shee that ran flawless with the stock dual carb setup. i switched to the single carb only for more low end for mx racing. i don't know the elevation here but i live in upstate ny syracuse , i would say 2000- 3000 elevation? sorry for the book thanks.....
