WEEMANSHEE Posted October 9, 2007 Report Share Posted October 9, 2007 Banshee has fmf sst's 260 main 27.5 pilots, air box lid removed & boyesen carbon reeds. Ever since I bought my Banshee the left carb leaked fuel. When I set the carb float on the left carb between 20 & 22mm my fuel leakage problem stops, but in 6th gear at WOT for a couple hundred yards the left side burns out of fuel!! If I set the float higher then I have a leaky over flow and the carb will still go dry after a longer run at WOT. I pulled the carbs & cleaned them several times, I also checked for blockage in the fuel lines. I have pulled the fuel valve from the tank & cleaned it up. I don't know what to do next. Is it possible I need a different fuel valve or bigger fuel lines?? Thanks in advance for any help. Quote Link to comment Share on other sites More sharing options...

bonbon Posted October 9, 2007 Report Share Posted October 9, 2007 PINGEL !! Agreed. I need to get one too. I was draining my carbs running up sand mountain this last weekend. And if all else fails......fuel pump! Quote Link to comment Share on other sites More sharing options...
theshee Posted October 9, 2007 Report Share Posted October 9, 2007 Get a pingel valve and that will take care of it. I doubt your bike would, but you can still suck your bowls dry with a pump, my 10 mil will suck the bowls dry with the stock bowls on my 40mm carbs without the oversize bowls on long runs. A pingel valve is a lot easier then drilling the cylinder for a pump too. Quote Link to comment Share on other sites More sharing options...
Twyztid Posted October 9, 2007 Report Share Posted October 9, 2007 That might be what happed to me Saturday. I ran mine hard for about 1/4 mile on a smooth gravel road and when I slowed down to downshift and do a U-turn it was revving higher than normal without any throttle input. I ended up hitting the kill switch and turned off the key and it still took about 20 seconds to shut down. I realize that this could be caused by other things such as an intake leak or bad jetting but running a float bowl out of fuel also seems like it might cause that if that cylinder got a lean condition from running on basicly just fumes and got hot enough to make the motor diesel for a short period of time.

als660r Posted October 9, 2007 Report Share Posted October 9, 2007 Also check your fuel cap for a plugged or resticted (sp) vent . Quote Link to comment Share on other sites More sharing options...
