Split second power lost

[Claude J. Greengrass]

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.

Well, I was wearing hard boots... and anyway QS is sometimes blinking when I am using the clutch... (?)

May be a timing issue then. Try this, slow down when you're shifting. Pull in the clutch shift let it out again. See if it happens then. Them just use the quickshifter, no clutch. I honestly don't think there's anything wrong with your bike. Just most likely need to get more used to it's quirks.
