Never had a two stroke before, I built a banshee from the frame up, fast built the motor for me, 66.5 bore, hot rods stock stroke crank, milled and re chambered head, ported jugs with booster ports welded in, v force 3 reeds, Fmf fatty pipes. My question is this thing runs great till the upper rpms then good god this thing runs like a striped ass ape. Is this normal two stroke stuff or "poweband" as I hear

Thanks fellers, being new to the banshee world every little bit helps. James 21 I don't know who ported the jugs but every bit of them has been touched, including a weld on the lower side of each cylinder where a port has been increased. Assuming this was to thicken the outside of the cylinder . Is this common? Will post pics of what I'm describing

Bought my buddies 95 banshee non running for $500. This thing is rough and beat up and I'm restoring it. My question is I have taken the cylinders off and cross referenced the numbers laser etched on the pistons through wiseco and they are the 66mm. The bores seem to be in good shape but the cross hatch is worn down. I plan on sending the jugs to full bore online to do a 66.25 or 66.50 bore on them. Is this a waste of time? I'd like to keep the jugs because someone has spent some time porting the shit out of these.
