Engine vibration

[Tone]

Hi All, Is a vibration at around 4,500/5,000 revs, normal? If so, is it the engine itself or a sympathetic vibration, thanks, cheers Tone.

Got the Suzuki engine bars? Feel that before that rev range and then in it.

[Tone]

OK, what am I looking out for? If I feel the vib through the engine bars, does that mean it's just the frame, or still can be engine.

[MartinW]

No, it's just the bars amplifying normal vibrations in that rpm range. Remove the bars and it will be gone.

[bigpie]

Take it to dealers, Suzuki might refund the price of the bars. I'm trying my luck when I get chance to visit.

I have not got engine bars on my v strom, but am thinking of fitting some, bit worried about more noise so asking the question, can you not fit some rubber washers to reduce the vibration, or is that not an option.

[MartinW]

Some people put a rubber spacer in the Left and Right side join at the front. I'm not sure whether you can put them on the points where there bars contact the bike as they would need to be splayed a bit and the bolts would need to be a bit longer.

I can't say I have noticed the vibration but I don't commute on it.
I think it really depends what you are used to. My previous bikes were Aprilla Pegaso single cylinder, 26 yr old zzr, 25+ yr old Gpz and a drz 400 on muds. The strom feels as smooth as silk compared

[Jacko]

Why did you sell the DRZ? It's a great bike to run alongside a Vstrom.

[Kayaker413]

There was no over lap. I replaced the pegaso with the vstrom.
I would love another dirt bike but funds aren't favourable.

I bought my drz outright a few years back now and it was sold to fund other adventures.

[joderest]

Are you talking about the pegaso with the 650 rotax engine ?
If so, I always thought they were so much more better designed than the BMW f650, which used the same engine.
I suppose it was Italian flare over German understatement.
I must admit, after running an F650GS, the V Strom is super smooth, and using an engine that pulls cleanly from under 3000 rpm is a godsend, no quick changing down to get going again.

Regarding this engine bar vibration problem , has anyone tried filling them with sand a la tingling handlebar trick ?? Am not sure if there is a hole where they join in the centre , but I can feel a small one in the back of the top bracket where the tube meets . Reckon a fine funnel and some silver sand would do it , if you took them off first , of course. I think it changes the resonant frequency or summat. Or am I talking rubbish ?

[Jacko]

Also, I find it's always handy to have some handfuls of kiln dried sand on hand should you need it.

[Madyokel]

Is it not the same stuff?? The gear you sweep into the cracks in Your block paving ?

[Jacko]

Yup. I have a bag of it if you need some for emergencies.

[tallpaul]

The gaps in my block paving Is full of dog sh*t and weeds. Silver sand...Is that what you are supposed to use instead?

[Kayaker413]

Slightly hijacking the thread but yes the rotax 650. It was a good bike and bought second hand of a design engineer that works for Jaguar, so it had all sorts of special mods. I very nearly kept that to ride offroad but as I did all the paperwork for my Strom a bloke came into the shop and asked if it was for sale (as it was parked next to their p'x bikes), so I couldn't really say no at that point.

He bought it as a garage project bike but to date he has done nothing to it and rang me a week after buying it to say he was having more fun on that that his gsxr or silverliner. (he had a bit of folding from his business reckoning lorries)

[Madyokel]

Further thought on the singing engine bars , how about oil? Assuming there is no hole at the bottom of the bars , you could probably fill them with a small tube and a funnel or squeezy bottle , and a lot of patience , followed by a rubber bung , without taking them off the bike?
