Question about 2008 Ducati Multistrada 1100 S

1 Answer

Vibration Problem My Multi has a high frquency vibration across the rev range. It is most noticable in the seat and if you touch your knees to the tank. It is bad enough that 3 bolts vibrated out of the muffler cover. Has anyone had a similar problem? I think it may be worn main bearings. Bike has only 8 thou on the odometer, and serviced at correct intervals. Started this about 2000 miles ago, not getting any worse. Bike runs fine, idles fine. Any ideas?

Try to isolate where it is coming from. try listening with a screwdriver held against your ear and various locations on the running motor. does it happen in neutral or when moving, ect.? might want to drain the oil and cut open the filter to see how things look.maybe your flywheel got loose?

Lots of vibration suddenly


Is it the engine or the frame? Only noticeable when riding or stationary as well?
If the frame (so only there whilst on the move) then check the front wheel alignment. You could have thrown a wheel balance weight or if you hit a pot hole, then the forks could have moved from straight and inline if the fork brace or triple tree worked a little loose. Check the wheel is tight at the axle bolt and the pinch bolts are tight. Are the head race bearings ok? Get the front wheel up off the ground and try pushing and pulling the wheel forwards and backwards. There should be no movement in the front end other than being able to turn for steering.
If vibration when stationary, at idle or through the rev range, then if the engine isn't running "lumpy" check out your engine mountings.

I own a 96 fireblade and when you ride very slow at about 2-3000 revs and shut the throttle you get a lot of slack and a knocking sensation you can feel it threw the foot pegs its also bad at 6-8000 revs...


Ok, clutch slip,would not be noticable when you back off the throttle so mutch, you would mainly notice slip when accelarating as the engine speed would increase but not your actual speed, as if you hadn,t let go of the clutch fully
Is the noise noticable through all the gears? Does. The bike jurke when the noise is present?
If it does i would check these items externaly.
The condition of the drive chain, rotate the wheel and check for missing rolers from the chain links, remove front sprocket cover, and observe the sprocket for broken or missing teeth. Also check if the sprocket has exsess play as if the bolt were loose, if so remove and check shaft condition for dammaged splines, next look at the rear sprocket for broken or worn teeth, missalignment and tension, all fixing bolts, next grab the sprocket firmly top and bottom pull to and fro as if you were pulling from the outer and not in a rotation , you are now looking to see if the bearing in the carrier on the rear wheel has failed any exses movment would mean replacing the bearing, this would contribute to vibration, if this is ok press the chain downwards check to se if the engine moves, sometimes engine bolts become loose and vibration would again be evident, check engine subframe for damage cracking etc. Vibration can also derive from front and rear wheel bearings giving a visible vibration in footrests and handlebars in extreme cases, good luck my bet is chain and sprocket, poss carrier bearing, paul

I have a CRF100 and it has excessive vibration


Make sure all of the engine mounting bolts are tightened properly. One loose engine mount bolt can cause exactly what you are describing. While you're doing that, perform a visual inspection of the attachment points on the frame, making sure there are no visible cracks.
Aside from that, just stick a wrench on every bolt and nut on the bike that you can see - and make sure everything is tight.
The only other possible thing I can think of would be a loose flywheel on the crankshaft. Unlikely, but check just to be sure.

I have a suzuki gsxr 750k3 with a arrow can the front pipes are


exhaust will not cause vibration, maybe a fluttering sound if they are loose. engine vibration at high rpms is detrmined how well the engine was balanced at the factory, thats why performance and racers take apart the engine and have it balanced better than factory. only thing you could do is make sure engine mounts are all tight. anything else means taking engine apart 13k is way fast rpm,so if it doesnt shake at 10k, not to worry.

Vibration below 4000rpm


Hello cloaky...does the vibration seem to be more RPM related than speed related on your gixxer? Can it be felt more through the grips, or foot pegs? Any noise along with the vibration?
The 99 GSX-R600 has been subject to recall for the replacement of it's faulty cam chain tensioner (NHTSA CAMPAIGN ID Number: 99V132000) Dealer supplied and installed at no charge under warranty... corrected the problem of cam chain tension but the damage of shorten chain life for most owners, had already occured. Didn't know if you were aware of this...so i thought i would mention it.
Hope this helps...

Handle bar vibration/shaking RVF400


Hi there!

I have the same problem but i finally had it fixed.
Your front rim is warped. Have it aligned. Balancing alone would not do the trick as this would only balance the wheel on its vertical axis. (assuming they were able to balance it properly)

Jack the front end up and turn the wheel.. Have a screwdriver or any thing that can serve as a guide with the rim, turn the wheel and if it touches the screw at some point of the turn , then the wheel is misaligned. A new stock rim would cost too much so have it aligned with a good machine shop.

To give you an idea of what im talking about:
www.webbikeworld.com/Motorcycle-tires/wheels/

There's also a chance that the fork fluids would cause this. Fluid levels should be equal. (less likely)

Hope this helps!
I'd appreciate a feedback!

My '73 Norton 850 Commando handlebars vibrates at idle.


Hi pl427
I love these bikes. Vertical twins of this era vibrate, is just how it goes. Engine design was simple back then and no counter shafts are used, so there is a degree of vibration at low revs produced by 2 big bore pistons that will make the handle bars get a real bogey on at idle.  If the carbs are out of sync,or need a tune, then you may have a lazy clyinder at idle that is producing the vibration also. Not sure if your bike has them, but some have rubber bushes that mount the handlebars. These can get sloppy with age and may need to be replaced. Another trick if the vibration is anoying you is to mix some lead shot with silicon and fill the ends of the handle bars up to "weight" them and reduce the vibration.
click here to see one walking on its center stand. Notice the way everything is vibrating on this old girl.

Vibration


The carbs should be synchronized every 20k miles. If you are having a roughness in idle then I would recommend the carbs being synched. If the problem is at higher RPM's I'd check to see if the motor has a harmonic dampener that can be adjusted. This often resolves vibration issues. I'm just not sure if this bike has one. These big bikes usually have some sort of adjustable dampening device internally.
I'd also like to have you check the motor mounts. This is a common problem if your bike has any rubber in the motor mounts. The rubber wears or even breaks and you often cannot see it until you actually try to remove the mount. Often they will fall apart in your hands.
These big motors all vibrate a bit so many of the manufacturers have realized that adding modified motor mounts is helpful.
