Just had a dynojet quick shifter fitted. It's really a toy for me with a fun factor and it's on my 2014 cbr1000rr and not a track bike. The guys that fitted told me not to use the quickshifter below 6000 rpm . This was only after I asked them if there are any guidelines. Does anyone here have any guidance for usage. I have to say it feel amazing and the shift from 1 , 2 , and then to 3rd feel like you have ignited booster rockets. Can't wait to try it out on a long straight.
