I will be teaching myself how to preload gear lever and shift clutchless. Cheers.
Suggested is developing the technique by first using the 4,000 - 5,000 rev range and light throttle openings.
Preload the lever to take out whatever "mush" you have in your boot, "slack" in the shift actuator train, to yield a slight net load at the verge of movement of the shifter drum.
A sharp throttle roll off coincident with final movement of your foot, and voila, you will be in the next gear.
As soon as you roll off the gas, snap it back open to where it was, be that partially open or wide open.
Also, proper chain slack helps - by not hindering.
2-3s and higher only by this method.
1-2s should have some clutch, even if just dabbed or fanned.
When I was doing track days, I never got to clutchless, as I was leery of the increased drivetrain shock loading plus the potential to blow a shift.
I ended up leaving the throttle pinned, and fast dabbing the clutch along with preloading the shift lever.
I got faultless shifting, and the tacho would only gain a few hundred revs during the clutch slippage phase.
