Hi guys,

Let mi know if those vibrations visible in mirrors are normal, visible when i pass truck?


Road is smooth, new tires (on old was the same), bike is stock, stock exhaust, crash bar installed (before was the same).
It is strictly connected with engine, because when I don't push it hard is better, still vibrating but no to so hard. When I push clutch lever it is zero vibrations.
Ok I know it is not electric motor and will vibrate on some level, but i feel those vibrations are to much. When I rev engine on neutral it vibes in the same rpms, but because of no drag (mean engine hasn't speed up the bike) a little less.
Chain is set about 30mm. So no so tight as manual suggest.

For example I see some guy on fz but his mirror are clear now matter which rpms.

Of course dealer keep statement that vibrations on triple are normal. So how to explain that? Sadly I have no opportunity to ride other fz, no mention about xsr, which is not popular. And of course dealer has no any of triple available to check to compare when I was there.

I want to claim it, as well as clutch sound described in other topic (before dealer change needle bearing in clutch the vibrations were the same, so it is not connected with replacement, in case of questions about it)

Thanks in advance

The bike has hard mounted, instead of rubber mounted bars, so a lot more vibes will pass thru.
If you think the vibes are too much in the lower rpm range, get a throttle body sync.
I have a converted slide show of the throttle body sync here
Usually though, throttle bodies out of sync show up as low speed surging.

Thx @RichBinAZ for reply,
however before I recorded it I checked the TBS. In theory this should be adjusted during 10000km service.

Taking into consideration that is time consuming operation with little/no benefit i heard many dealers don't do TBS, it is also hard to check it and prove it. I regret, that I didn't left any signs known only to me to verify it.

So, as i don't trust them, I checked it by myself additionally, wasn't perfect but not so off
Before:
Publication Gas Wood Cylinder Glass


After:
Wood Publication Electric blue Gas Metal


Total level is different, because I had to adjust it lower - vacuum after reving sucked liquid way too high before.

Both measured on the same temperature. I observed that level of liquid between cylinders (vacuum level) is very temp dependent and can differ at 80degC and 100degC which both are normal working temperature...

After adjustment I have more stable, smooth low rpms, but change is hmm cosmetic.

I have no vibration, mean buzzing till 5-6krpm, of course forgetting about clutch vibes, which I fell on 3-4krpm on little throttle, but this not blur the mirrors at all.

In case of vibrations on mirrors, handlebars, foot pegs and even seat, nothing changes after TBS. On video it is 7-8krpm, when people mostly tell that engine smooth out.

I worried it can be somehow unbalanced clutch basket (I saw one topic), broken clutch basket or friction plate (more topics).

Personally I want to ride more, worry less, but till warranty exists I don't want to be f*@#$ by yama or yama dealers, if something with bike is wrong.
After warranty period I can manage it by myself, dissassemby as much I can and verify, or bring bike to mechanic. But if something is broken by design, or not assembled well I don't want to pay for it.

My handlebars are filled solid with BB's and I've taken other anti vibe n measures and with over 55k miles I've never found the vibration objectionable but my mirrors still are not smooth as glass, the left more than the right.

Try heavy bar end weights and try packing them full and solid with BBs.

Then ride it like you stole it and don't worry about it.

When dealer solve nothing I will have no option and do BB trick.

I tried grip puppies, but installed on stock grips made it so thick and uncomfortable so I uninstalled them after few rides.

I bought bike with bar end mirrors, maybe they were less blurry, but seems that OEM mirrors due this vibrations somehow dump a little handlebar vibration. When I came back home on bike with constant speed, my fingers were tingling a lot, I thought it is the barend mirrors falut (it is model installed on OEM barend) as they change the barend weight.
And in fact oem mirrors damp the vibration of handlebar a little but for the cost of blur.

I've ridden many Triumph triples inc the Rocket, the Spwezuki waterbottle and the original Yam triple XS750, they all have vibes. But I find them more pleasant than 4's and twins.
My wife loved the Rocket a little too much

My '16 FZ 09 has no vibes and solid mounted bars. My mirrors are glass smooth at all speeds.

Handlebar vibration is very annoying to some. It was a main contributor to getting rid of my FZ 07. Had planned to keep it along with the 09, but going back to those buzzy bars was no fun. I knew I'd never really ride it for that reason.

I tried to record the vibrations and blurry mirrors on constant speed about 150-160kmh on 6th gear, to show you better what I experience.
In reality, mirrors were very blurry, even more than when I accelerated in video in first post, and calmed down totally after pulling the clutch. So in 100% it is not tire related.

But somehow on recorded video I could only wavey reflection in mirror without blur. Maybe it is connected with frequency set on camera? I dont know, I only changed battery on camera, maybe settings had reseted. Need to look into that.

But coming back to the topic - I left bike at the dealer, we will see what they'll find. But according to what I understood, they have no idea what to look for. They told me the issue could be different model of mirrors vs MT. Ok, I told them to swap them and check, btw I could do it by myself, as I have mt07 in a garage... But generally I felt that they will not find any issue, and later try to explain it as bike character. I asked mechanic about recent service to try to guide him if he could have not noticed the broken friction plates (hardly possible if you have to remove them to proceed bearing replacement) or basket (more possible which as I saw it can crack, but not break in two parts). He convinced me that all parts were ok. But maybe now if he will look there one more time will be more focused on it.

One thing more:
What I observed during the ride on a highway, is vibrations at the same rpms but different gears differ. For example on second gear mirrors vibrated during acceleration, on the same rpms on 6th gear same vibrations are on constant speed, so conclusion is the wind create similar drag and effort for engine like acceleration on slower speed. I dont know if it is any hint, which can lead to some components like chain or sprocket. Bike has near 9000km.

That is normal vibration on the XSR900 at those RPM levels. I killed the camera in 3 phones before I realized it was the bike doing it. It also killed the Bluetooth module twice in my escort radar detector. I added vibration isolation bolts to the radar detector mount and took the phone mount off, no more issues.

The bike is smooth while cruising and the vibes under hard acceleration or high rpms are not uncomfortable so enjoy them. If I need to check the mirror I pull in the clutch.

As a side note I have noticed that there is a reduction in vibration felt and in the mirrors on this bike and my Raider when you put an aftermarket exhaust (just punched out the plugs on the Raider). Seems that absorbing the sound dissipates some of the energy as vibration.

Different exhaust can definitely change vibes on a bike. Arrow exhaust I put on my FZ 07 made the whole bike throb, especially the seat, but the twin engine is makes more of a thumpthump than a buzz so it wasn't too bad.
It made me apprehensive about changing the exhaust on my 09. Luckily, the Yoshimura I ended up with changed nothing and the bike stayed glass smooth. It's really the luck of the draw if an aftermarket exhaust will increase, decrease or have no change at all in regards to vibration. I'm sure managing those sound waves is someone OEM's pay attention to vs aftermarket companies who just bend up whatever pipes to fit their universal glasspack to our bikes.
