Either electrical of pnuematic, both systems cut the ignition by a programmable amount via the CDI some use pressure sensors on the gear lever and others have buttons to up and down shift. It's just for bikes when a gear is selected the gear arm returns back to a 'zero' or 'neutral' position not much good for a lammy.
Iv'e emailed a couple of manufactures but not had any reply as yet,

the thing is...a bikes gear lever returns to a central position after each gear change ...i wont bother explaining how they do this but as far as bikes are concered the quick shift only needs to move a few inches either way ...up or down the gear box

on a lammy as im sure you know the gear arm stays in a position that coresponds with what ever gear you are in

so imo a quick shifter is no good on a lammy or vespa for that matter

That's the fundimental problem `i see with the quickshifters i've been looking at, they say they are 'programable' so does that mean they can be programmed to shift in a single direction and stay there, I went to the NABD ( nat association for bikers with disabilities ) and they have a coiuple of variations with up and down shift systems based on clutch lever pressure and though that looks good would it work on a lammy !!

I would like to know if anyone has tried one and it worked

i had thought about fitting a quick shifter when i used to sprint......this is how i thought of doing it...
fit a positive stop on top of the casing (i think Don Noys fitted one to one of his scooters a triumph one i think)
have a selector and gearbox made so that neutral is where first would be and equal spacings and then fit an air shifter to the selector arm....simples ;)

Downside is the cost only to get say half a second over the quarter :(
i found you can get quicker with practice and not eating too many pies ;)
wheelie bars would also get you quicker time

good luck

sonny i spose it cud be done if you had a ratchet system on the gear linkage on top of the engine so the ram pushed forwards , then returned ready to push forward again. mite be difficult to change back down tho. the neutral where 1st sounds good .mite get 5 gears in there then. you could always try a rearset gear change. id like to see if anyone has put a steering damper on a full frame. tim
