This product is a must-have
I purchased the bazzaz qs4 quickshifter and I am very happy with it. This product was a little time consuming to install (maybe 3 hrs) and adjust but once it was done the product worked flawlessly. This install required minimal hand tools and light mechanical skills. If I was to install another one I might be able to install it in half the time. On a scale from 1 being very easy installation to 10 benig very difficult I would say this was a 3 do to the plug and play instalation with no wiring, cuting, or soldering and the software which is really not needed do to the pre adjusted cut times, is very easy to use. I highly recomend this product. Thanks to RevZilla I got the quickshifter fast and at the best price.

I have a Bazzaz full system ZFI TC . It came with a Bazzaz shift switch which is not working correctly anymore. Should I be getting the QS4 or Bazzaz Shift Switch With Strain Gauge Technology ?

Would this fit in my 2009 Suzuki B King as I understand that it has the identical Hayabusa engine ?
