So ive had the qs4 on my 2012 ZX10R for about 1000 miles now. I can only compare this to some OEM Quickshifters never tried another one. The shifting is obviously great in the higher RPMS the shifting is seamless. Very good in the mid rpms if youre a bit on the throttle. Acceptable in the lower rpms but not good (like all the other QS) understandably, as its not what its for. Its mainly a track mod but i find it very enjoyable on the street. Overall a great mod, very happy with my purchase, Revzilla delivered it faster than quoted.
Note: Not the hardest install but many steps, takes a while if you have basic knowledge. If youre experienced and know your bike shouldnt be a problem
after a small lowside the strain gauge was no good had to replace that for 250.

Do I need any module on the bike to make it work or I just plug it and I will work?
A shopper on Dec 13, 2014
Hi Revzilla / Fellow Users,

I'm an avid street/track rider from Singapore and just recently acquired the 2014 Kawasaki ZX-10R. I've decided to get a quickshifter from Bazzaz. A well known bike shop here in Singapore sells the Bazzaz Z-Fi QS (Fuel Injection + Quickshift) as a whole (wanted to post the webby but saw your disclaimer on not including "links to other sites"). I did some online research and true enough, it really does exists. However, I noticed that both you and Bazzaz's official site sells the QS and FI separately. My question is:

1) What is the main difference between the combined and separate units (other than having 1 or 2 items mounted to the bike)?

2) If I purchase the QS4 now and decides to add in the FI in the future (not near future), can that be done?
A shopper on Jul 24, 2014
BEST ANSWER: Don't they use the same plugs? Like the speed sensor and neural detect? How would you be able to use both products? (QS4 & Z-Fi) Would you need to buy a special harness? I have been trying to figure this out but Google isn't helping.
Is this this the model with the sensor that is both standard and gp shift? The sensor that doesn't have any moving parts in it.

BEST ANSWER: Yes. This is a strain gauge unit that works for both regular and GP shift patterns.
Hi guys
I've installed the quick shifter and now I've bought the z-f1....can't connect the 2 because they both need the Cps plug.
Do you have a loom who allows me to connect both ?
Or do you have any ideas in what to do?
Thx in advance
A shopper on Sep 30, 2014
BEST ANSWER: I'm looking at doing the same but I have the z-fi already installed just wanna add the QS. Would it be possible to hard wire (solder), the wires of both units together and use the one plug?

ATM this is my main concern but I guess I won't know till I've already purchased it huh?
