Bury That Speedo

Insane numbers today. Recent tweeks are paying off. This is a modified Bike Berry Angel Fire. 66/80 cc, stock head, Bofeng carb, F2 trust pipe into a shark muffler, NO Reeds. I wasn't even going to film until I realised I was busting 7000 - 7500 rpm every couple minutes. This is the belt cam view, ( phone stuffed in pants) . Surprisingly stable but you see the motor vibration go threw my gut right into the cam!
