I told my dad I went to a Banshee Forum and he told me about a problem he is having with his bike to see if a solution could be found without taking it to a shop. As far as I know his bike has no engine work done to it just FMF Gold series pipes/silencers, still has TORS if I remember right, runs pump gas. He said it does fine at the low end, starts building up to the top end fine, then just bogs down really bad at the top end. I suggested taking apart the carbs and cleaning them, he said he put SeaFoam thru them, but I don't know anything about that stuff. Any tips or insight would be appreciated.
