bruce can i ask a question? if you wanted low end WHY THE HECK DID YOU BUY A BANSHEE! you should have got a 4 strke,banshees are made to SCREAM DUDE!they dont have low end from the factory and it dont get much better,i have dealt with rob and john on nearly a dozen engines they do all my porting now,every time i put one together it makes killer power.i have tried several different others compaines also,nobody has made as much power as those guys or been as professional. if they offered to buy your gas and give you moneyback,why the heck are you whining and bashing them?guys like you dont deserve a banshee,ever heard of a 400ex or raptor,you can putt around on those
