Split second power lost

[Claude J. Greengrass]

Hello,

Today I decided to check acceleration under good conditions (no traffic, dry road) so while in 3rd gear I full-opened the throttle. The bike sped up very quickly as expected and kept accelerating but within 2-3 sec lost power for a very short time (fraction of a second or something), then came back again. I didn't glance at the instruments, as my entire attention focused on the road...
Any explanation? Is that perhaps the wheelie prevention system (lift control)?

Was the gas tank getting low. I asked because my Gen 2 will starve for fuel and it's getting close to empty long before it actually runs out.

what modes were you in ? Try it with all traction stuff set to off ?

Factory/default ones. I see no reason to deactivate lift control, I intend keeping me and the bike in one piece, thanks

He's saying the the TRACTION CONTROL not lift control might've kicked in due to wheel spin and pulled power. Lift control doesn't pull power as aggressively as TC does I've noticed. I have mine set to TC off LF 1 EB 1 QS 1 PWR 1 I could actually feel a difference in power delivery once I turned the TC off. It's more "direct" feeling.

Yeah really if any traction (or abs) is on you may get a very small "blip" of power loss, it reacts damn quick

Good, I will then stop worrying about a possible hidden trouble or something, it must be the traction control. thanks

Hi. I am building a G 1 busa with over 350 HP on the street and up to over 800Hp in race setup with no abs,tc or lift control.

Oh, I wish you every success. While at my age (64) speed is the opposite of my objectives ;-)

Did your foot push slightly on the shifter?

That’s an excellent point too. If noticed the problem everyone here seems to have with the quick shifter happens when I’m lazy with the up shift or I’m wearing a flexible shoe. In my riding boots I never have a hang up or momentary delay in power.

I run Lift and TC off all the time. I race a 2 stroke motocross bike so maybe it's just the old school in me. My ZX10 doens't even have these fancy controls. Did this happen during a shift using the quick shifter? Is it possible there was something on the road you didn't see and the TC kicked in?

WERE YOU USING THE QUICK SHIFTER WHEN THIS HAPPENED? That's the important part of his question.

I think it had 3d gear but now you planted the doubt!

Lots of people have had a similar thing happen while up shifting using the quickshifter is why it matters. It's happened to me and I think I've got it narrowed down to "lazy shifting". I my riding boots that have a very stiff toe box it's never happened to me. But when I'm wearing my Doc Martins or tennis shoes is when it'll happen occasionally.
