Im having a problem with a 2002 Banshee I just bought. Ive ridden it a couple of times and keep having the same problem. When I take the bike out of neutral into first there is a really large dead spot in the RPMs. I feel almost like I'm 1/4 through the gear before it grabs and makes any kind of acceleration. It wants to move but it sounds like its gonna spitter out and stall. This problem happens through at least forth gear (thats all Ive had it up to thus far). It feels like the engine isn't getting enough air and its choking itself. Ive cleaned out the air filter and Im still having problems. I need that low speed because I do a lot of trail riding. Thanks for the input.
