Opinion: Shift kits

[Fabian]

I do agree with you JimGuy.

The way speed limits are forever being reduced to insanely low numbers as a method of gaining ever larger government revenue (seems to be chronic issue in Australia), there is no longer any joy owning a motorcycle for use on the road network; the only real option being recreational racetrack events.

I concur: I neither want the expense, speed, traffic issues nor insurance

I use a Staton Inc crank kit myself, it allowed me to keep the auto shift feature on my Land Rider bike.

Still I feel I should warn you Florida is really tough on motorized bicycles. You can have electric assist or be classified as a moped.

Florida law 316.003(77)


(77) MOPED.--Any vehicle with pedals to permit propulsion by human power, having a seat or saddle for the use of the rider and designed to travel on not more than three wheels; with a motor rated not in excess of 2 brake horsepower and not capable of propelling the vehicle at a speed greater than 30 miles per hour on level ground; and with a power-drive system that functions directly or automatically without clutching or shifting gears by the operator after the drive system is engaged. If an internal combustion engine is used, the displacement may not exceed 50 cubic centimeters.

A cvt drive system or an auto shift system like I have on my rear wheel may get you around this law. Since any gear shifting would be automatic and not being done by the operator.

if they only stretch, keep them on untill they break.... i have had chains that have "stretched" and i took a link out and they are still running atleast 1000 k's after

Once you get past 75% chain stretch, the sprocket profile gets hammered out of shape and a new chain wears prematurely when running on an excessively worn tooth profile, apart from the fact that worn sprockets can cause chain suck as the altered tooth profile resists a smooth release of the chain roller.

I found this out the hard way back in my early days of motor bicycling, initially unable to understand what was causing the problem. Fitting a small video camera and observing the action made it all clear.
