I just bought a 2005 Banshee, my first small issue is I think that the bike is jetted rich it has Bills pipes on it and bigger jets in it, I'm not sure exactly what size. The bike idles low, and if I'm not running it hard, or if I'm running it in low rpms the left cylinder coughs and misses. There is little power in the low rpm range, but it seems to clear up and run good higher in the rpms. I need to constantly rev the engine while I'm not on it to keep the left cylinder awake. The previous owner told me I may need to check the air to fuel mixture. I just think it's jetted rich. What do you guys think? Also I don't know what screws on the carbs adjust the idling or fuel mixture, I do not have the owners manual. Also when you adjust idling is it possible to mess it up so that one cylinder will idle faster/higher than the other? Or is the idling linked?
My second major question is I plan on installing V Force 3 Reed Cages with Carbon fiber reeds. I ride trails in Pennsylvania and I stay out of the mud as much as possible. What is the best air box/air filter mods for trail riding/hill climbing. I've seen some kits that eliminate your air box all together, but I'm not sure if that is such a good idea because I will be in dusty/snowy conditions at times. Should I wait to rejet until I've installed the reeds, cages, filter, and airbox mods. Would the bigger jets be more likely to run better with these mods?
I've owned a fourstroke for 10 years, this is my first two stroke, and I love it. I just need some guidance, all help is appreciated!
