Shifting improved with flash or PC5?
« on: August 23, 2019, 04:15:16 PM »
Hi guys, wife has recently burned out clutch on 900 trying to let it out slooowly to get over abruptness when changing gears. Takes me a few minutes to adapt as well when I get on the Z. I remember reading at one point some members who had got either flash or PC5 and said the shifting/fueling had improved? Can anyone verify that? I will put new clutch pack in (winter project) but if either of these two mentioned will help then I would like to go that rout. Now my wife is definitely not a pro, but has had ninja 500, fz 07, and now the Z9.. no troubles with other bikes.
Thanks for help

I am no help on a tune
but
The z9 slipper clutch is definitely funky. I have a 16 tooth front sprocket and recently put in Brocks HD clutch  springs ( says HD but only 10% stiffer) which really makes a noticeable difference. Plus with a total cost of under $80 it is more than worth the felt improvement   :028:

I was on a gsxs-s 1000 site a while ago...I had nearly purchased one a few years back but report of a terrible off/on throttle kept me from it. When I spoke with a national rep about it, he said "because of trying to meet emissions the fueling is the way it is", but said a power commander fixes it. Anyways a few of the guys on that site mentioned that the Z900 also had a bit of snatchy throttle, which I hadn't really thought of. I have also a Ninja 1000 and have to say the Z900 is kind of snatchy on-off compared to it. Maybe it was only a few models, not sure, still a great bike.

Does she know the clutch should be pulled only a split second and then released as fast? Sounds like something is possibly done fundamentally wrong (maybe throttle control), can you take an action cam video and see what is happening?
