Quickshifter, which one?

For some reason I got this sudden urge to buy me a quickshifter. I've been surfing around for a budget solution but will be more than happy to get any input from community. I do have PCIII still installed so that can be used to do the actual ignition cutting. HM, translogic, Cordona which one to pick?
HM every time

I really wish I'd never bothered.
Pete did you have problems changing up through the box at speed/high revs, always had issues with mine PITA relly shit gearbox. Jody was having issues with his the other day.
I never used to have problems.

Since fitting the HM qs I've had more missed gears than in 6 years of SD riding.

I've got an HM too on the road it's fine, but when it's used on the track like Pete i get loads of missed gears.
Just to keep some sort of balance here, I have an HM quickshifter and it's been great. Been on track a few times and never had a missed gear. The only times I have had any issue is when it is my fault and I have maybe pulled the clutch in a bit or dipped the throttle, (old habits die hard), and it messes up the shift. It has always been my error, I believe), - even though I was maybe not aware I was doing it. I find it works better and better the harder you are pinning the throttle - it doesn't suit to be used when gently accelerating on the road. Better to use conventional clutch and shift.
I would recommend the HM plus as it can be put onto whatever bike in the future that you may own... Only need to change the loom from then on. You pick up speed so much faster with one. You shouldn't miss any gears when you set it up right... Sensitivity and kill duration. But only works well on heavy accelaration
I was thinking the same thing about kill time and sensitivity, has any of you guys tried amending the settings if you're getting missed gears?

At the end of the day the quickshifter does not control the mechanics of selecting the next gear, all it does is cut the spark to take the load off the engine so you can snick the gear in just like rolling off the throttle only quicker.

If gears are being missed I would say either the kill time is not long enough for the way you shift and so the engine is loading up again before you finish the shift or then the sensitivity is set too low for the force required to make the shift and so is initiating the kill time too early in your stroke and so also kicking back in before you finish your shift
I've had no problems with my PC based HM quickshifter.

One thing you should be aware of. Ideal kill time is not the same for every gear.
High end shifters have different kill times for each gear selection.

I have tried various settings and while it works well most of the time - at a circuit like Jerez with 13 corners I'm getting a false neutral once every other lap, sometimes worse. One missed change looses you all the time you saved from the other quick shifts.

While the other guy who hit me WAS at fault, too close and distracted, my missing a gear didn't help matters.
So far the only time my HM Plus has missed me gears was when the linkage came loose, i presume that was just confusing the QS!

Anybody used a Translogic QS4? I'm picking one up 2nd hand for about half the price of new, can't turn that down.
I've got a QS2 - really nice piece of kit >

I had the Dynojet. It worked fine but I too had many mis-shifts. The reason I think this is, is mostly from pussy footing the shifter. Racing, or at the track I suppose, you should be banging away anyway, right. The first mistake I noticed was the resting of my toes on the shifter. Any pressure would cut the engine, as it is supposed to. Once I started paying attention to my shifting technique, I realised it was mostly my fault, the problems I was having with the QS.
I dropped quite a bit of time with the addition of the QS but also lost a few positions a few times because of false neutrals. In the end it gave me one less thing to worry about as far as controls went.
I think they are a waste of time for the street and only needed for the track for racing or the guy that really challenges himself to make better lap times.

The fastest guys in our club rode the BMWs last year. Some guys went through a few trannys. When they went to the HM strain gauge type, that sorted the problem. They were using the stock QS before.

As far as how my tranny looked after the use of the QS? I don't know but I hope the thing exploded right after I sold it to that SDeric douchebag.
glad this came up ive been debating a qs this year or a brand new slipper, never rode a bike with either i have a pcv and was going to get a dynojet one but seems like more hassel than they're worth
If you have a PC3 you can program a lower limit in for the Cordoba so it ignores the QS under 3000rpm say. No stalling.
Race tec quick shifter, seams to need alot of adjusting, but when its set right it works well, its a read switch setup opposed to the pressure switch of HM
Does the sd produce a bang when you use a quickshifter? Or is that an inline 4 thing.
For example:

It depends on whether the QS cuts the fuel or the ignition. If it cuts the ignition but the not the fuel delivery then the backfire is getting rid of the unburnt fuel.

Personally I like the popping of IL4's. Don't think I've heard a twin do the same though.
Thanks. I love the sound everytime that bmw shifts. I never heard it on a twin as well, shame. Would be awesome.
I have the HM plus on my blade and it is super smooth and has not missed a gear change yet, I had a Translogic fitted to my R1 and I could never get the right setup still missed gears, in any of the switch positions.

So I would recommend the HM plus every time and as has been said before, you get a new bike you pay £40 for a new loom and shift rod and your away
I have a Translogic QS2 and I've never had any missed shifts - you just have to make sure the lever is in the correct position for your foot and then play around with the cut interval and yes it does pop/bang when shifting but not every shift - maybe 60% of the shifts.
I wonder if these folks have applied their wares to LC8s/RC8s ... Any of our kiwi friends know of this outfit?

Kinda like the idea of being to setup the interval so easily.
I actually have an old Techtronics one. I swapped a PC3 for it because I use TuneECU but never used it and I've no idea what model it is but there's a hell of a lot of wires.
My HM is the strain guage version that goes direct to the sparkplugs and it does pop and bang sometimes. Not always. And it does sometimes stall at lights if you change into first very slowly - you just have to be positive and it doesn't do it. I've had it fitted for about two years now and I have just got used to riding in two completely different ways depending on the conditions. Never use it when just pottering about, hardly ever in towns but as soon as there's any open road or hard accelerating you just automatically revert to quickshifting as a better way to go. The one I use just works better and better the harder you're going but starts to not make sense as slow speeds - simple as that.
