Ok, lets start with what i know. Just bought a 2000 banshee, told it was rebuilt from the crank up. Has pro circuit pipes with toomey silencers. No air box, single K&N filter with skin. Stock carbs, Tors removed, has new caps and cable (no idle kit ) I have one ordered , took the carbs off to clean has new parts, was pretty dirty though. Has 240 mains and 25 pilots, did not check the needle. Did compression test have 148 both sides. did the soapy water while running did not see anything. What is happening is it wont idle unless i pull the choke out, then if i give it throttle it bogs down like no fuel, if i rev the throttle fast i can get it through the bog then it revs to red line and i have to put it in gear and kill it ?? I actually have ridden it a little when i test rode it and once you get it past the bogging it goes like hell, but as soon as you get it back to idle and try to go again it dies like its running out of fuel? Before i bought it took it to a mechanic he said its running lean and thought if i replaced the old fuel and clean up the carbs it would be fine. Not so much, i got it to idle a little better, but a soon as its to operating temperature and its sitting and you rev it up it redlines and you have to kill it in gear. Did the soapy water when it was warm and running, assuming i am looking for bubbles, i did not see anything? any help any info would be greatly appreciated. If i now what the problem is i can surely fix it, but right now i am not sure what is causing my problem. Thanks.
