must say I got a good giggle on your CNS description. (not the last bit) I agree, and the most ridiculous is the non adjustable needle. i mean, really?! oh wait, and the claims by vendors "racing carb"!!!
Now, one thing i did find- I bored out a cylinder to the physical limitation of the cylinder. I added a huge pipe (KX 65) and I found that the super rich CNS actually helped reduce the ridiculously lean condition i had created. I only used it for a minute because I flat out didnt want all the cables and the lack of adjustability. I am going to try this PW 50 idea, although fyi we have been using mikuni 18mm carbs for our racers. "dream carb". makes the bike like a kx-60. although not for the carburetor theory & tuning inclined. overly adjustable, with a fair amount of balance when making a jet adjustment. it is unique in that the pilot jet is always in play, so it affects the mixture curve throughout the rpm curve. anyway, sorry for the ramble I'm not awake, but get a mikuni if you want real power and performance fellas.
