fleury_xlt Posted May 19, 2013 Report Share Posted May 19, 2013 Hi guys, today I was drag racing with my friend when sudently my Banshee start running on one cylinder. I've checked the spark plug, coil + cap (interchanged the spark cap on the plug), cleaned the carburator, checked the reed valve and i'm at 130PSI on each cylinder. The gas flow on each line of the carb, the air filter is clean. I've tried to put directly gas in the cylinder that is not working, without results. So basicly I have AIR, FIRE and GAS and the quad is not working properly. Really confused about that. Any ideas ? Quote Link to comment Share on other sites More sharing options...

noonansar Posted May 19, 2013 Report Share Posted May 19, 2013 Have you pulled the plugs and visually checked for spark? disassambled the carbs and completely cleaned them? It doesnt take alot to clog up pilot and main jets Quote Link to comment Share on other sites More sharing options...
BeeCanBanshee Posted May 19, 2013 Report Share Posted May 19, 2013 Check float needle? Had a similar problem but the float was sticking giving me to much gas and not letting it fire. Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted May 19, 2013 Report Share Posted May 19, 2013 If they are aftermarket carbs try swapping carbs,,do a pressure test on motor could have an air leak or coolant getting into cylinder,I have built and tuned 100s of motors it's very rare but I had a flywheel issue that left me pulling my hair out with similar symptoms you describe Quote Link to comment Share on other sites More sharing options...

That is weird !! Quote Link to comment Share on other sites More sharing options...
BeeCanBanshee Posted May 19, 2013 Report Share Posted May 19, 2013 Try swapping carbs like said just need a longer tube for choke that will yell ya if its a carb issue. Did you check the throttle cable to see if its broken? Is the choke tube still there? Quote Link to comment Share on other sites More sharing options...

bansheegoon Posted May 19, 2013 Report Share Posted May 19, 2013 X2. Its hard to help people when you say you checked them but you didn't. Seems like you know the basics you would have figured it out if you had checked all those things. Anyways glad you figured it out Quote Link to comment Share on other sites More sharing options...
