Thanks Ckau. Does that 3:1 ratio include the 16 tooth sprocket on the reverse gearbox now? (16T engine 39T axle)
So maybe I should look into a 36 tooth sprocket to get me closer to stock ratio? Or I could swap the internal gears as you mentioned too.
My Yerf had never really bogged down on any hills thus far, so I'd like to keep the same gearing.
My motor is modiifed decently. Nikasil 58.5mm kit, port matched intake manifold, NCY ported head, TK exhaust, NCY CDI
It ran really well at higher RPM before. It didn't seem to accel any better with the new gearing than before the change if that makes any sense????
