Since my last post I have destroyed the Shimano 3S hub. My Dellorto SHA got fouled with dirt and caused a erratic running condition which overloaded the hub. The second one seems stronger and is running well.

I still have a 19mm PHBG to setup. I am waiting for jets to arrive.

At this time I am using the stock carb and a another Shimono 3S (I have a few) as it gives a smoother power delivery to the hub.

I will continue to develop this setup with a stronger Sturmey Archer Hub and the 19mm Dellorto.

I find the 3 speeds are enough, 1st for hills, 2nd is direct drive and 3rd is great for the flats. It can shift when stopped as well.

I really enjoy winding it out in each gear.

Its a 66cc motorbike!
