Quick shifter not working

Have a dyno jet quick shifter on my bike recently it's started playing up.

When I try to click up the shifter physically won't move no matter how much pressure I give it with my foot.

When I use the clutch I can change gears as normal.

Not sure if there is actually a problem with the quick shifter it self.

Any ideas or things to inspect? Thanks in advance.

Re: Quick shifter not working

Your post doesn't make sense.

You say the shifter will not move, yet functions fine when you use the clutch. When you say "not move", do you mean under full throttle conditions you are applying pressure to the shifter and it is not shifting? I suspect if you blip the throttle it will shift fine without the clutch?

A quickshifter is just a pressure switch. Once it detects pressure being applied to the shifter, it either cuts fuel or ignition to make the engine briefly stumble. This is just enough to unload the gears and since the rider is applying pressure to the shifter, it changes gears. All a quickshifter does is allows you to maintain throttle position and it automatically blips the engine.

Don't confuse a quickshifter with an air shifter that is actually making the shift for you.

Before the problem began to occur I'd keep on the throttle and change gears without engaging the clutch.

However now when I attempt to do the same the gear lever physically will not move therefore I can't utilise my quick shifter.

I have to engage the clutch with my hand and change gears as normal.

Re: Quick shifter not working

Sounds like there might be an issue with the QS shift rod pressure/tension sensor

I've had the unit installed for over 3-4 years so that could be the case of wear and tear I'll have to do some youtubing and make some adjustments

Re: Quick shifter not working

I followed the instructions on this YouTube clip

These are the results I got https://imgur.com/a/oye9WSH so Iím assuming safe to say my device is faulty as the circuit isn't opening/closing as I simulated a gear change, just hoping someone can confirm for me as well.

And if anyone has an indication what components I would need to replace to get it working againÖ

Re: Quick shifter not working

Buy a new sensor. I wouldn't use Dynojet products, there are other much better options available. For example Cordona or HM.

I use this on my street and track bikes https://www.cordona.net/products/str...ifter-35687055

Re: Quick shifter not working

Won't get any issues if half other components half dynojet? Also if I buy a new sensor will it be simply plug and play?

Re: Quick shifter not working

Sensor itself is basically an on/off switch that closes or opens circuit depending on what system is used. So it doesn't matter what sensor you use. You can use your old sensor's connector so it will be really easy to use other than DJ product.

Re: Quick shifter not working

I'll have to check out how much I can pick up a sensor for and make a decision from there

Re: Quick shifter not working

Yup, they wear out over time. Some wear out faster than others. The Bazzaz sensor I have hooked to my ZFI-TC wore out after a couple of years. The nice thing about those (not sure of the DJ sensor has something similar) is that the sensor has a little LED light that activates when its engaged, so if you try to shift and the light doesn't light up its a pretty good indication you have a problem with the sensor.

FYI, make sure you are getting the correct sensor (push or pull) for your shift pattern (normal or GP shift).

Re: Quick shifter not working

First, in the most basic sense, the PC is a computer. Connect your laptop and check a few things. First, make sure your firmware is up to date. Next, disable the QS in the PC, power it down, power it back up and re-enable it. The solid state stuff in the PC can degrade and flipping the switch will refresh that cell.

Second, how many times did you test the sensor? One, ten, a hundred? I wouldn't trust one good test.

Third, I've never been a fan of how things connect to the PC. Everyone seems to be focused on the switch, but it could just be a bad connection to the PC. I don't know if the path is 5V or 12V, but losing a little on the supply pin, and then a little more on the signal pin could be enough that the PC just doesn't see the signal.

Lastly, your testing is flawed. Same as bad pins, the sensor could be corroded and "using" too much voltage. Your meter was in the 200k Ohm range for resistance. Drop it down to the 200 Ohm range (three clicks counter clockwise) and test again. See how much resistance the sensor actually has.

Re: Quick shifter not working

Yes, dynojet has the software and updates for free download. They also have very good support. Your meter should read close to zero. Ideally, whatever you get when you hold the probes together should be what you get when testing the sensor.

Re: Quick shifter not working

ill do the best that i can ill try downloading the software and turning it on and off/updating and go from there

ill try getting in touch with them also but im from down under (Australia) so it'll be difficult.

and try to retest again on the setting you suggested.

but im no means confident so feel free to post any youtube links or stuff that might help... riding without a quick shifter sucks

Re: Quick shifter not working

Did you also install the shift kill enable software? (more like a patch than it's own software)
