SHEEBANSAVAGE Posted August 3, 2011 Report Share Posted August 3, 2011 Hey all, My 03 banshee with FMF pipes and PC2 silencers, uni filter, boyesene reeds etc had a little issue this past weekend. I was at around 3500 feet in elevation and its pretty much jetted correctly for that elevation and I had an off idle/low speed bog and it ran ok at higher rpm's and sometimes at idle it would shut off on its own. I drove for a few K like this and then found my left side carb top (TORS) loose. I tightened it and it ran better at low/off idle but still would occasionally die at idle. I rechecked the top and it was still tight. So when I got home I removed the carb and the area under the carb top where you would remove the needle (top of slide) was really dirty..sucked in mud/water I guess. Inside the carb passage above the bowl had some dirt as well but it may have gottn there as I was removing the carb. I also noticed the gasket that sits between the carb and the carb top is not attached to the carb top anymore. I pulled the reed and it was ok. I also noticed that I had gas/a clean area on the carb at bowl height just before the intake boot and that intake clamp wasn't completely tight. As for exhaust, more oil out the Right side than the left. So I was running leaner on left than right So, what do u guys think, just a dirty carb from the loose carb top, gasket maybe not in place properly, loose carb to intake clamp or something else. This should have nothing to do with it but, Both float height need adjustment or needle/valve changed--This is getting fixed this week as well - Let me know what u think.

SHEEBANSAVAGE Posted August 10, 2011 Author Report Share Posted August 10, 2011 Anyone have an idea.. Unfortunally, I live in an area where I cannot ride from my house, so I would like any other opinions or other things to check before I head out again and possibily ruin another day. Any info would be appreciated. Cheers Quote Link to comment Share on other sites More sharing options...
black sunshine Posted August 10, 2011 Report Share Posted August 10, 2011 I recently blew my motor, and the side that ran lean had an air leak at the carb top. I asked everyone and their brother if this could cause a melt down lean condition and the overwhelming answer was NO. Good enough for me. Do you have the "keeper" tabs in place? Do not over-tighten the tops. Just hand tight, no channel locks, and install the keepers. Over -tightening will cause the throttle to stick as well as screw up the carb top seal.

SHEEBANSAVAGE Posted August 10, 2011 Author Report Share Posted August 10, 2011 Thx for the reply. I do have the keepers installed and in order to keep the tors part of the carb top from wiggling, I had to use channel locks to get it snug. I think the top should be tight to prevent air leak and crap getting in there. What do u think? Was your tors still loose a little after it was hand tight? Let me know Quote Link to comment Share on other sites More sharing options...
christofferson73 Posted September 17, 2011 Report Share Posted September 17, 2011 I'm also at 3500ft. What mains and pilots are you running. I'm guessing the combination of problems caused the problem. Have you risen it since addressing the issues Quote Link to comment Share on other sites More sharing options...
90Bansheedude Posted September 17, 2011 Report Share Posted September 17, 2011 In my opinion, an air leak at the top of the carb, or anywhere for that matter could cause a leaner condition than what the bike is jetted for and pulling in air just through the air cleaner, and could cause problems. Really, most people said No it wont? Quote Link to comment Share on other sites More sharing options...
