How do quickshifters work? Do they do up and down shifts? I presume you still need the clutch?

Is this a thread to see who has the least ability to research shit for themselves?

I'm surprised you can fucking dress yourself in the morning.

LOL, yes. But have just tracked down a contact for somebody that will know for the application Im thinking of.

Sorry, too tempting a shot not to take it :drinknsin

Short answer, quick-shifters work by cutting the spark (and thereby reducing load on drivetrain) to allow the rider to make a full throttle shift, either the normal way or with electronic actuation such a solenoid or pneumatic cylinder. I've never used one of course, but I'm pretty sure the idea is incompatible with the use of the clutch.

Was the absence of the f deliberate by any chance?

Clutchless full throttle upshifts,I've used them in 250 Superkarts and will be putting one on the Sidecar

Cheers, have been sent links over night for a unit I think will work. Looking for something to help somebody thats disabled and they make units for that in the US. Found that so paraplegic guys race, they get strapped to the bike. Very cool.

[imdying]

If that is your purpose, then it is not a quick shifter that you want.

What you want is a Pingel

[G4L4XY]

I need one so I can get to the dairy faster hehe

[cheshirecat]

Whats a dairy faster hehe. Do I pull it instead of the clutch

[G4L4XY]

You can pull whatever you like sir

[The Reibz]

Pretty much cuts the ignition (or Fuel) allowing you to keep the throttle pinned wide open while you change gears (clutchless) and resumes it once the change is complete.

Normally a solenoid is attached by the shifter which sends the signal to the ECU/Powercommander to either cut the ignition or fuel.

You can also run a airshifter which is operated from a button (usually the horn) which will change gears for you without you having to use the shifter at all.

Your welcome...

Q = how do quickshifters work?
A= they work bloody well

The MV's is a gem to use. Even with mild acceleration at low revs it snips up a gear like magic.

Funny thing when the F3 came out a new owner moaned on the Owners forum how badly his worked at changing ...down! Doh

Well I should know by now not to ask motorcycle tech questions on KB.

I did ask on one in the US and it has lead to a discussion with an engineer over there. Hes going to do some prototyping and see if what we think will work does. If so we may have created a low cost and easy to use shifting system for people with a disability on their left side.

They could just get an old Triumph. You would then have to find a way for them to use the rear brake

Depends on what you call low cost, there's already push button shifter systems available

why would you bother engineering one up? there are plenty already available on the market. I have a simple air system in the shed that still requires u to use the clutch if you want to and push a button to either move the shifter up or down through the gears. Or you can go full on and get the ign cut ones so you dont have to use the clutch either.. What else would you want?

If hes a paraplegic maybe one that operates off brain signals... and steers the bike too.. and brakes..

free..

when you get one for your LCR can you get me a low cost one as well for me' Windle?

Low cost as in very cheap compared to push button systems. Its all just an idea at this stage. I would like to think if it works and somebody that is disabled needed one I could give it to them or sell at the cost of the parts.

As I say, its still an idea.

Good man, what's the level of disability? Might be able to help out with a few parts or designing if you need it.

[pete376403]

I read of a system many years ago that was on a CB750 sidecar used by a guy whose legs were stuffed. A micro switch in the clutch lever operated a solenoid for shifting, the indicator switch was rewired to control the direction of shift (up or down). Nothing flash, but it worked.

Thread dredge but this is underway now. The said bike is being rebuilt over the next couple of months. System is stupidly simple. I will be trialing it on my bike to ensure it works. To be fair it may stay on my bike and another made for the CBR.

Disability is a fused ankle and lack of flexibility in the left leg so normal shifting just wont work.

Neither will standard quickshifters as this is going on an old carbed bike.

Not sure how you plan to throttle blip a downshift on a carb bike.

I assume you are now trying to move the gear shifter but still let rider use throttle control and manually pull clutch lever.
This would mean its not really a quickshift kit just a automated gear change.

Quickshifters were around well before Injection became standard, they're not hard to find for carbed bikes

Agreed, I was calling it the wrong name by the looks. But they can kick the stock shifter down for a down shift so all we need is an upshifter. Will have the foot gear lever at more of a trail bike height.

He will need shift to neutral down from 2nd manually.
As long as you leave clutch and throttle stock and use it just for up shifting the shifter should be fine. Same as a normal shift just bypass the foot movement. Idd button on the rt side in a position that suits a slight throttle off on the hand and activate with thumb.

[nodrog]

What you want is a Pingel

no shit........

Hmmm, wonder if you could use the starter button for that and mount a second starter button.

Wiring would be easier if you used small button and wire it to a relay. Get the relay to take the load not your switch.
There will be plenty of momentary on waterproof buttons available that you could custom bracket to the correct spot to easy switch.

Pingel are fucking rubbish compared to the decent stuff like translogic

Yes I would relay it. Will have a think about the electric options. Question on the one you posted is how would it cope with backwards movement with a down shift?

Looking at its design idd say its normal state is pulled in (activated) and the spring fires it onto the shifter. You would set it with room(empty air gap) for the down shift.
You would need a normally closed switch or a normally closed secondary clean contact on the relay. The second would be the better way.
There would be some adjusting to get location perfect.

I would presume it would have a reasonably strong push so I could mount it close to pivot point to get the free play. Not something I have ever played with so interesting.

Thanks for that.

Yes but think of the solenoid pulling it in fully then when you push button you de-energise the soliniod coil making the spring fire it upwards shunting the shift lever up.

He was best with pianos

[Supertwin Don]

I built a couple of "shifters" for Junior Drag bikes a few years ago - used a truck starter motor solenoid triggered by a button on the bars. Had an electronics mate who cobbled an ignition cut out triggered by the same switch. Always thought about having a switch which reversed polarity on the solenoid to work it both ways so that it could down shift as well (Drag bikes don't have much need to change down!) If you go electric watch the polarity of the ignition system!

[nodrog]

they are talking about something to move a gearlever for a paraplegireno (which is was the pingel was invented for), not a full on race shifter for lazy cunts.

[BMWST?]

just get a shifter of an old scooter,pull clutch,rotate grip shift one click...done

[dickie]

I have a tuono v4r aprc with a quick shifter and it's brilliant when carving up twisties and as far as I know it momentarily shuts the ignition while shifting without clutch and man the noise is great !

That is one option. This one a guy in England will make for us. The lever turns with the unit.

Mines no good. Kills tyres in 2tho km and wheelies a lot. Does burnouts leaving corners also.
I have managed to tame it now and run my bike in rain mode.

MB Developments, Mark Broadhurst, been turning out trick bits for Lambrettas for ages and I thought it looked a bit like his racing gear change.

There are a few options out there which fit 22mm bars for scooter racing applications.
