A shopper asked: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?Jul 24, 2014
Charles P: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.May 7, 2015
A shopper asked: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 advanceSep 30, 2014
