Hey there....
I have an '02 banshee, basically stock (T-6's, 280 main jet, toomey filter), and didn't get to ride much over winter...so it just sat in the shop. Last weekend, I went to Sand Lake, Oregon, and TRIED to ride this thing. Every time I took off, it would bog-out VERY bad on the bottom-end, like it was just drowning in fuel. I was feeling like crap, and didn't want to mess with it, so I just put up with it. I couldn't make it around in first gear without having to feather the clutch. It only had power up past the power-band, absolutely nothing below that. Anyway, it ran so bad I lost to a 400EX stocker....I took it home, took off the carbs and cleaned them out, blew EVERYTHING out, clean as a whistle (I think). I set everything back to where toomey suggested (float height, needle groove, fuel/air screw adjustment). Put the carbs back on, started it up, and it idles fine with both cylinders firing like perfect. As soon as I get on it, though (about 1/4 throttle), it seems like the left cylinder almost completely shuts off (fires about every third time I'm guessing), and I'm only running on the right cylinder. I'm getting fuel and I'm getting spark to both sides. So maybe I have a bad gasket or seal?? I haven't ridden the crap out of this bike so the motor should still be strong. I will check the comp. tommorow. Please, any help is greatly appreciated here. Thank you.
