I have a 1987 Banshee 350 that I’m trying to re do. I picked it up half re done from this guy. The mods on it are a cool head (don’t know what domes are in it but I was told to run race gas) Tors delete, brand new T5 exhaust kit. I put in the toomeys “Perfect” jet kit (280 main and needle) and installed the carb with no air filter. My air filter does not have the air filter box, it is cut out. I’m using VP T2 Race gas, Pre mixed 40:1. I topped my machine off and kicked it for a while and would even start up. I’m sure it’s flooded but am I using the right jets? Maybe other problems? i had an old beat up aftermarket exhaust on it, it had a 230 main jet and guessing stock needle. Ran okay but definitely coulda been tuned better. Any ideas? Thanks. I’m from Wisconsin and our level is about 1400 ft. the picture is how it sits now and the video (if it posts or comes through) that was about a month ago with the beat up aftermarket exhaust with the 230 main and stock needle. The air boots to the carb were not hooked up all the way to carbs. Please let me know what you think I should run and ideas. Thanks IMG_6606.MOV
