Hi, i had a great ride on the weekend, wearing no ear plugs and listening to the engine and noticed a 'click' or 'tick' noise I hadn't previously heard seemingly coming form the engine.

Happy for someone to tell it's normal - but I'm curious and a little concerned something might require attention. So here are the details -

Bike 1090RR currently has around 5000 kms .
Scenario 1 - 3rd gear, engine winding down between 3-4000rpm, roll throttle on 'click'.

Scenario 2 - 3rd gear, constant throttle around 4000rpm, single 'click' noise.

The noise does not happen all the time, only occasional, but possibly becoming more frequent (or I'm just listening for it now).

I'd appreciate anyone's thoughts on my 'click'.

Thanks

Only in 3rd gear? Your bike has a slipper clutch?

If everything else seems normal and you are only hearing the odd sound under decel or accel initial load I would think it is the clutch and nothing to worry about....but I don't have a slipper clutch on my MVs, so not really familiar.

Yeah, I recon Ed might have something there, maybe just have a spin on those wheels to check hub and front wheel bearings, but if it's that loud then I'll agree with Ed.

I've noticed the same thing. I'd describe it more like the sound of a valve flapping open/closed. Gear doesn't seem to matter for me, but it's always right after I twist the throttle and right before I feel the acceleration.

I think the OP may be talking about something else but I certainly have exactly what you just said

"valve flapping open/closed. Gear doesn't seem to matter for me, but it's always right after I twist the throttle and right before I feel the acceleration"
all i can add is for me its a gear change and at the very start of acceleration so like a slow speed corner where you're intentionally changing gear and rolling on very slowly. I've not experienced it under heavy throttle when im riding like an idiot, although it would be harder to hear\feel then anyway

What concerns me is when it happens at slow speed turning a corner that half a second of lost power could make me drop the bike.

Ive also had 2 other issues:

On 3 occasions my bike has been in 1st or 2nd (first i think) and pressing up to go up a gear feels like im in 6th gear. ~no movement have to drop the clutch and re pull so i can up gear

The other issue is a handfull of times (hasnt happened for a while) i've gone to second , and its slipped out to neutral. Someone on here indicated it could be a clutch spring but my clutch takes much more pressure than my old bike ever did

Ill see how it goes my bike only has about 5k on the clock ill get them to check it out next service, it could be me not engaging the gear or clutch positively enough, stuff wearing in, or something stuffed (hope nothing too serious)

Took the bike for a ride over lunch and played with this.
Gear doesn't matter, but it was easiest to reproduce in 3rd.
I could reproduce (my flapping) sound by engine braking to below 3k rpm and then coming onto the throttle relatively quickly. *flap*, power...
I'm pretty sure I can feel it too, not just hear it.

As the bike warmed up, I had to let the revs get lower and lower before it would happen and then after about 30 minutes of riding I didn't get the sound anymore. This would suggest to me it's an intake or exhaust valve opening/shutting at certain rpms to warm the engine up.

It's possible his is different but he mentioned coming from rolling off the throttle to on triggers it, and after my poking around today that would be exactly the same thing I'm getting.

Only I don't think I've ever had it during constant throttle...

If you had engine valves sticking, your bike would run like shit, maybe not at all, do not mistake engine valves for the "flapper" valve in your exhaust, big difference right there.:stickpoke

If you still have the valve in the exhaust, I would disconnect the cables from it and then test the bike, this would leave the valve open permanently to give you a better idea of what's going on.

Didn't mean to give the impression that the engine valves were sticking... run like shit is a bit of an understatement there. I'm no expert but I think it would be safe to assume we have interference engines

I meant more the exhaust flapper valve that's common on many cars and some bikes. Do the brutes have a flapper valve that blocks one of the intake boots?

No, no intake flapper on any MV........there is an exhaust tuning valve on some of the new 3 cylinder bikes. Not sure about Brutale 675/800, pretty sure it is on the F3.

Pretty sure it is not on the liter and larger bikes.

Its still there had it tonight don't think I even changed gear , roll off , roll on , flap noise, keep rolling on

It sounds like the air box but I understand tank removal to play with that , plastic sounding?

I'd love to remove this thing I feel it does nothing for the bike but piss me off ~brutale 920 if people could also comment on my other issues not had them for a week but tonight I tried up gearingnwith no clutch it worked fine; makes me wonder

Everything that has been discussed here indicates that you are talking about the clutch. It is normal and nothing to worry about.

Hotsuma, the mapping of the bike will not allow low speed low rev throttle control. If you have the bike on a stand idling, when you crack the throttle even the smallest amount, you will find it jumps to 2000rpm. There is no middle ground. It is the nature of the beast.

I have never even heard of such a thing on any bike.

Wasn't aware the newer model 4 cylinders had an exhaust tuning valve....

As to the air box flapper, quite a few bikes have used them to control air box volume at varying speeds. Doesn't cover any intakes, rather the air inlet to the box, kind of like a partition. Air cleaner box resonance is a tunable item you know.

That's why those nice little K&N filter pods on street bikes look nice but kill horsepower....better to put the high flow filter in the box and leave the boots connected to the carbs.....but it doesn't "look" as good...:stickpoke
