Shifter Kit Installed

Still breaking in the kit and sorting out issues, mostly chain related.

Its fun to ride up and down the gears. A different technique is required.

HI,

I bought the kit but am waiting for my full suspension frame to come in before I try to build....Just curious but what did you mean by a different technique is required?

Thanks!

Andrew

PS - I guess in between gear shifts one has to get off the throttle and roll it back on slowly but do you have to clutch or just let off the throttle?

By different technique I think he means starting it but he will have to elaborate. Because of the front freewheel you actually have to pedal to start it. You cannot bump start it by just getting the bike moving and dropping the clutch.

No clutch action is required to up-shift or down-shift. It actually won't work if you do. Just like when you are riding a bike normally you have to have the chain moving to shift. The only time I ever use the clutch is starting or stopping. If you are coming to a stop just shift in to first and then just before you stop pull in the clutch. Because of the rear freewheel you pretty much can up-shift or down-shift at anytime.

Rolling off and back on the throttle will make your shifts smooth. You don't have to but you will put a lot of stress on the drive, freewheels, cassettes and axles if you don't.

Update:-

It is now reliable.

I moved to a 3 speed hub setup.

It is geared to do 22mph in first then 30 in second & 40 in third.

Future mods include a dellorto carby and pocket bike pipe.

Well now we can check internal hub off the list. Let us know how the hub holds up.

HI Wildmere,

Just curious but which internal hub are you using?

Thanks!

Andrew

Its a Japanese made Shimano model 3S, supposedly fragile but we will see.

When or if it blows I have an English made sturmey archer ready to fit up.

Added the expansion chamber today.

Its a tight fit but it works.

It runs to 44mph now

Dellorto to come

The header length is adjustable on this setup

Nice bike. Really nice pipe. Let us know what the carb does. Which Delorto?

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!
