question...blew my stock motor on a 97 banshee...bought jugs and pistons that were .40 over....never used...i put the engine back together and ever since the motor rebuild it has no power band...almost seems as if the choke is contstantly on...never clears out...i rode it for about 20 minutes and same result...modifications are minimal...pipes,reeds,280 jets,and of course the .40 over...if anyone has any ideas as to where to start or what could be a possible problem i would greatly appreciate it...thanks
