Preloading the gear shift linkage causes the stationary shift fork to sit against the spinning gear pairs. If you don't think that will prematurely cause the shift forks to heat up, bend, and wear out, you're wrong. And doing that with a quickshifter in the loop can cause the switch to be tripped, interrupt the ignition, and all without the proper force on the shift linkage to begin with. In race conditions, with an engine teardown and rebuild every race or so or when crucial milliseconds are measured, it might gain you something. For all other people, preloading the shifter just causes you to post threads on here asking other people why your shit don't shift right.

I'm not going to pretend I know as much as you do because I know I don't. The only reason I initially thought that preloading the shifter is a good idea is because it makes clutchless upshifts smoother and improves their success rate (compared to botched shifts). Points taken though and thanks for the comprehensive breakdown.

If I intend on tracking a bike or racing it then I would certainly invest in an aftermarket shift star like the Factory Pro. I believe it makes for a cleaner mechanism and reduces the overall wear and tear.

No need to preload with a QS, you're risking engaging the sensor and or it not working when you go to shift. Just push/pull on the shifter and bang through the gears.

After two seasons on my bike the transmission/clutch were absolutely fine with no abnormal wear and no parts were replaced. I replaced the clutch in the third season just because.

+1. Also agree with not using the QS between 1 & 2. Too much of an rpm difference and too much torque to screw things up.

I'm only experiencing this when I do a half ass shift.

How many miles you got on it? I'm at 27,000km so far with no gearbox issues. I have however experienced problems when I had the QS ignition kill times screwed up by confusing one timing setting with another. This would cause the shifter to cut and reignite before the shift actually happened, sticking it in the same gear even though it blipped, would get a big jolt doing it and nearly throw me off the bike.

Is it possibly the sensor or ecu has freaked out and for some reason the QS thinks you're in 6th gear, so it's not compressing, stopping you from shifting up?

Gents, I too had this issue with my gen 5, when changing from 3rd to 4th under heavy acceleration the QS wouldn't cut the ignition, and i wasn't able to go into 4th... this happens around 8k i think....

I thought it might have been the QS, so I had the Woolich QS installed and the Woolich tune flash the ECU.

Unfortunately I still have this issue from time to time... I've learnt to live with it.

Race bikes take a lot more abuse than street bikes.
