ok so ive been trying to figure out why im having such a hard time to find the problem.this is whats happening,the banshee starts up on first kick with out the chokes and seems to idle ok.it seems like the right cyclender is misfiring,and im thinking this cause the left pipe gets hot and the right one is cold compared to the left.i started off by jetting and then moved to ohming out the whole electrical system.then i even changed the coil and same problem,then i changed out the stator and pickup coil,now i ve even changed the cdi out and same problem.all these parts came from a good running bike.so now i dont know what to do.ive done compression test and both cylenders are at 170psi.i did a leak down and it held 6 psi for 15 min with a .5 psi loss.i have a 4mill 421 at +4 timing with 35pwks,new plug boots on coils.i dont now where to look now and im almost ready to give up.could the reeds be the problem.i also used 3 sets of plugs and the right one seems wet and left one is deffinatley firing.i need all the help possible PLEASE

mine kinda does the same when its real cold, but its my left cylinder. i have a dent right at the beginning of the header. check the bottom of the pipes, are they dented at all?

Carbs...sounds to me like you have something clogging your pilot on the right side not allowing enough fuel or any fuel into the right cylinder! I'd pull them apart and clean. If your reeds were causing this your compression test would have been bad on that cylinder.

I had the same problem but my misfire went away when I would rev up the bike --- thought about a plugs wire bad so swaped left to right then the misfire went to the left side -- changed plug wiires and the misfire went totally away and now it seems to be more responsive -- now to finish the front suspension
