how much mo powa is that gonna give you?

[Phelan]

~10% increase in torque, at the expense of ~10% top speed in each gear.

[fordnut79]

Exactly, cant wait to try it out

Well.!? How was it??

[fordnut79]

Not what I expected at all. I was expecting more of a hit somewhere in the power delivery, but there is just more torque everywhere; Kind of weird.
Makes it hop off the line harder.
The bike definitely feels much lighter somehow. And less clutch work in parking lots too.

I did opposite, installed big front sprocket and small rear wheel sprocket + bigger diameter rear wheel. Now minimal speed is 15 miles per hour at 1000 RPM, but the top speed at 5th gear is higher.

TPEHAK--out of curiosity, what is the max top speed you have reached?

[TPEHAK]

I did not check. Max speed I rode is 70 mph.
