Tuning PJ's with 4 mil

[bansheemxkris]

Hey all, i just bought a banshee that the previous owner tried to convert to alcohol and never got the jetting right. I wanna to convert back to race gas. Does anyone know approximately what the needle, main jet and pilot jet should be. I am 1,000 feet above sea level, 4 mil, 18cc domes, agressive dune port, K&N Pods, CPI big bore pipes, 34mm PJ's. THanks!

Those pj carbs have the actual alky conversion done? If so sell them, and get some pwk's or even strykers with the money. The pj's are an ok carb, just a little more finiky in weather and temp changes then most carbs. Not to mention if there is humidity, your day will definitely be less then stellar. I used to spend so much time playing with mine that I even had myself convinced that I liked to wrench on it as much as I like to ride it. But if you are bound and determined, start off with a 158 main, and work your way down. You may need to go as low as say........152. For the needle, you didn't say wich one you currently have in them. Just start the needle on the bottom clip and worked up. I actually got rid of the cgl needles that came in mine for some del needles and It helped tremendously. For a pilot, maybe a 58-55. Start bigger! I learned every thing I know now about jetting from mistakes. Expensive mistakes! Man I wish I knew about this site the first couple motors I destroyed as a kid. A child left alone with a built banshee will either become a wiz, or the biggest quitter you met. Good luck man.

Yes, they already have the conversion done. I was just going to buy some bowls and swap the jetting. How much do you think i could get for them? Im am not sure what needle is in it and the current main jet is a 168. Thanks for all the help! This site sure makes things alot cheaper and painless.
