I find it hard to believe the DMC916's aren't working for ya.. What do you mean the powerband comes in late? As long as the jetting is right those combustion chambers will make that powerband come alive really quick! Anyhow, go with the T5's and throw T6's out the window.. NO mods huh... We'll that's what I though like all other Banshee riders.. I say T5's because my stock bike ran perfectly well on them. As booker said, if loosing the powerband, a flick of the clutch will bring it back. Now I run a Port, K&N Pods on Stock carbs, VF3's, shaved flywheel 12oz, cut head .035, +4 Timing, on compression of 140/145 the T5's provide a broad powerband across the board on all gears.. 5th gear wheelies when I dump the clutch at the drags!
