hi im new here and i just got a 2003 banshee.i just went throught the whole bike.it didnt run that great so i cleaned the carbs and now im starting to think that wasnt the problem.it starts fine but doesnt like to idle and if i hold a steady throtle the right hand cyclender will start to skip.if i get above mid range it clears up and runs fine on the top end.the only thing done to the bike is fmf pipes and a air box lid.not sure where to go from here.

take your air filters off and see if your carbs open at the same time when you push your thumb throttle. sounds like they might be out of sync.

did that they are opening both at the same time.i even set them up to the clymer book too and same thing is happening.it seems to run better with the choke out very little.is it possible there could be some thing wrong with a jet

Where do you live? Maybe someone is close by and can help.

What do your spark plugs look like? Also, check to see if the mixture screw on the carbs are the same as the other

ok i took the carbs off agin and checked them out and didnt find anything.i also made sure the right hand bowl had the jet also.the carbs have a 250 main with a 25 piolet.its still has the air box and only has fmf pipes.i think the air box lid is after market cause it is clear.so i think its one that has more opening.so i would consider it as a air box mode also.i brought the air mixture screws out to 2 and half.the plugs are a nice golden brown color right now.i havent really rode it much yet cause i want to get it running right first.

start by turning your airscrews in to 1.5 turns from seated and warm it up. then turn them in a little at a time giving time for the engine to catch up, or out, untill it reaches highest rpm, and tun in a little bit after that. also, replace your plug caps (boots) if they are old, and check the pickup gap clearance on the flywheel.
