I have a 2001 banshee that was stock, with the exception of a big K&N with no lid on the air box... it had 200 jets in it (stock). I just installed an FMF fatty exhaust with turbine core silencers, and when it came to rejetting it, i figured i'd rather go rich than lean. *280's seem to be the main jet to use when the nice weather comes around... but considering that its like 10deg outside right now, i put *300's in it. The machine ran well before i took the carbs off. I soaked them in carb cleaner and they're clean as a whistle, i threw the jets in... and put it together. With my luck, it ran horrible... no idle, horrible mid throttle, and no pull up top. I parked it... then i did some searching and realized that being the moron i am, i put the slides in opposite as i should have (so essentially, they were in backwards). I pulled them back out and installed them right. I then sync'd the carbs (only with the dot in the sight glass while i held the throttle at WOT) I did NOT look at them with the throttle in the closed position, nor did i check to make sure they're moving at the same time... as i probably should have. I took the plugs that were fouled from before, and cleaned them up good and put them back in. I started it up, and it ran clean at WOT (didn't ride it though, just blipping the throttle) However, i have the same issue still where it won't idle AT ALL and its blippy when i try to give it a tiny bit of gas to keep it running. So it seems as i didn't make any head way... what the hell? this thing ran decent when i took it apart... all that i messed with was swapping the main jet, and i did move the needle down to the 4th position. I tried the air screws, and got them close to where they should be (1.5 turns out)... also i tried to move the idle with the idle screws on the back side of the carb (still has the TORS)... it did nothing at all as i turned it in little amount at a time, then i reached a certain point and i tried to start it up and see if the idle moved, and the RPM's sky rocketed, then fell off and it still died. I'm pulling my hair out here... Any advice would be huge, greatly appreciated! thanks in advance
