I get a kick out of riding this

.... yes, literally it gives a kick, as slowing down this R312.

it's like the revs surge back up on overrun, at low revs, but definately above the idle speed, as coming up to junctions etc.

Not all the time, but quite a shove when it does.

I'm still getting used to it, but is it normal?

So what you are saying is as you slow down it speeds back up?

The 312R (as some previous 1000 F4 iterations) has EBS; on the 312R I briefly had it was sometimes a bit unpredictable, as you describe. Apparently the EBS cut in intermittently, so you lose (part of) your engine braking briefly.

The 1078RR I now have has EBS (better sorted I think) Šnd a slipper clutch. Very smooth, pleasant and predictable. The new F4 has only the slipper clutch. I found the engine braking very fierce and not to my liking, being used to the 1078RR.

kind of speeds back up, yeah. Not a noticeable number of revs, but a definate 'shove'

I had put it down to EBS but as it does it about 30% of the time, i'd rather not just assume.

Could it be that the engine speed, closed throttle, and road speed is just on the lowest threshold for EBS to fire no.2, I don't know.

Never had a bike with EBS before, but whatever this is, it sure made me jump the first time it happened

I think it's some kind of chip thing, as the EBS is computer controlled. My 312R had it, my 1078RR doesn't. I remember it as a little shove forward, which, in the beginning at least, caught you unawares and required you to apply more brake. I recall one instance in particular where I was hard on the brakes going off the motorway onto a nice 180 dgr righthander, and releasing the brake induced the forward shove. Let's say it was interesting.

It's not really a shove of course nor a rev surge, it's the sudden absence of engine braking that catches you out. Have it checked, but you'll get used to it; nothing to worry about.

Hope this was helpful.

I still have fond memories of the 312R!

Hmmm
My 312r EBS appears lately to be not playing ball.

I think perhaps that it has the same thing as you describe, and if when slowing down I dont pull the
clutch in before say 2-3000rpm's then it snatches, and actually snatches the chain as if I suddenly
hit the gas from being off the gas.

REALLY annoying more than anything...it did not use to do this, and perhaps as I have read before
excess engine heat can damage the ebs relay, so bearing in mind that my bike did have a severe
heat problem, perhaps the ebs is on the way out....?

Keep us posted people ! Looking like could be my 3rd warrenty claim....dooh!

Cheers
