Just got a call from my dealer; they have got an answer from Honda Belgium!
Honda claims it's an upcomming problem/issue with bikes who are 35 kw ( restricted) and have the quickshifter installed.
The restriction and quickshifter interferes somehow in the software/mapping and that causes a stutter as soon the 6k rmp is reached.
Tomorrow I'll bring my bike to them & they're gonne remove the restriction, reinstall it and remap it with new software.
What they will do excactly/change I don't know but what I know, is that the bike won't be ready untill next week
As soon as I have more info to give about this 'new' problem and what the exact solution was, I will post it here!
I’m just back from my dealer (only had time this weekend to take it back home)
Problem = solved ✅
—> they removed the restriction complete (software and the smaller air intakes) + quickshifter! Then they’ve build it back on the bike with new software on the ECU. And with that, the problem was finally solved 😅
It’s still fairley new problem as I said, only 2 other bikers in Belgium have this problem reported too.
Guess this is the downside of being an ‘young’ biker that needs to ride restricted bikes 😉
And as you guys said & I expected, it was on their costs.
