Hello i need help with my shee..its a 2001 banshee all stock with just twin k&n air filters with no box ....whats happening is that when my throttle is at 1/4 the bike engine hesitates to run, but ones i go 1/2 it pulls really hard and at full throttle goes fast but stops making power at high rpm. Does anyone having same issue ? Or what should i check ..thanks in advance guys
