Does it work in GP shift ? Or up ,and down shifts?
Doesn't really work for clutchless downshifts. You would need a blipper for that and I don't believe the Healtech is currently blipper capable. If you think you're fast enough to blip before the kill time ends, you can try. No thanks for me.
I have a ZX-14 friend and his Healtech selected 85 mls in auto mode. He recently set his up manually and he is using a 30 mls cutoff delay with 75 mls for the lower rpm shifts going to 55 mls for the faster rpms.
My HM Plus shifter doesn't have shiftkill delay and is not programmable/gear or rpm. I use 90 mls and it works across the board. I will try 85 mls kill time. I get a bit of a tug as the ignition comes back on at high rpm and that is telling me the killtime could be shorter. I know 60 mls is WAY too brief for the high rpm shifts on my ZX-14 although it works well up to about 6000 rpm. Even my ZX-14 buddy has 85 mls with his high rpm shifts when you add in the cutoff delay.
I would suggest starting with lengthy kill times and work down to briefer ones. If you miss gears and it slams back down under load or backtorque, it's etremely rough on the gear box. You will find chunks in your oil. I did and I think it's gear dog slivers.
Use adaptive mode on your Healtech and that should provide a good refference point for manual settings. I think the busa gearbox might tolerate faster shifts than the ZX-14. I would not assume that to be the case though. Those high rpm slamdowns are brutal as hell. If you get stuck in false Neutral, grab the clutch lever and just stop wherever you are. It's darn near impossible you will ever match speeds after bouncing off the rev limiter, hesitating for a second while the rpm drops to idle speed and then trying to blip to the correct engine speed to shift back into gear smoothly. Just do your bike a favor and stop to shift in. One guy said it might smoothly shift up or down out of false Neutral on it's own if you coast with the clutch lever pulled.
If you want me to post pics of my ZX-14 buddy's Healtech settings, let me know.
