Hi Guys & Gals

Before I spend my life saving at the local dealer I was hoping someone could point me in the right direction.
I have a 2014 V-650 with 18000 km on the clock. This Sunday after a spirited run I started getting a heavy Shudder when accelerating in 5th and 6th gear.

This only happens under throttle and more so two up. The Versys always had a mild shudder when accelerating but now the bike shakes/shudders violently and if I keep my foot under the shift lever I can feel the lever jumping up and down.

Things I've done:

New oil and oil filter 10w40 Motul
Adjusted , cleaned and lubed chain
Adjusted clutch cable
Checked for loose bolts/nuts
Searched this Forum and google to avail.
Have I burnt my clutch out or done more serious damage? Any advice is welcome.

It's got to be a fueling or spark issue. Most likely cause fuelling. As long as the engine is sound, which it should be with only 18K, it is most likely an electronic issue with a bad sensor or controller. Get dealer to diagnose problem but not fix it. See what they come back with first.

I have a higher mileage bike that has been ridden hard and no issues. This is unlikely to be related but do adjust the valves, they can be a bit tight around this mileage and higher mileage.

Is your air filter clean? Can your engine get enough air at high RPM? It's damn near impossible to burn an oil immersed clutch out on a bike like the Versys 650 unless the clutch was improperly adjusted without enough slack in the cable. You would know immediately if the clutch was slipping by the RPM fluctuating without corresponding changes in speed.

That would be the clutch slipping under load... Your clutch cable was never too tight? Did it always get JASO MA motorcycle oil?

You're not the first to have that happen. Most have simply upgraded the clutch springs with stiffer ones.

Barnett's clutch springs are about 20% stiffer than stock, whereas EBC clutch springs are said to be 10-15% stiffer. EBC's CSK7 clutch spring set (5) $12.99, and Barnett 501-50-05055 (MT-55-5) spring set $17.06

It is possible to remove clutch cover without draining oil, by leaning it over more than side stand allows.

Will check all the suggestions thanks. Appreciate it.

Always used Jaso Ma oil but the cable adjustment never felt right no matter how I adjusted it even after I took it to the dealer so your diagnosis is more than likely spot on but I'm no mechanic.

Going to try find some aftermarket springs here in South Africa which could take awhile. If/when I'm successful I will report back.

Thanks for all the advice. Appreciate it.

What is the condition of the sprockets.
If the teeth are worn and hooked then under load and higher gears they tend to bind then snap out of the chain giving you a uneven shudder as the chain whips around the sprockets.

Drive chain slipping on a worn out countershaft sprocket? That would be quite extreme... In this case, it's actually the wet multiplate clutch which is slipping and shuddering when under increased loads.

One end of the gear shift mechanism is mounted on the engine gearbox spline.
The other is mounted to the foot-peg hangers which are in turn rigidly mounted on the frame.

If you can feel the end of the gear leaver going up and down then there must be movement happening between these two points.

This can only be because the engine is moving in the frame if the foot peg hanger bolts are tight.:frown2:

Recheck your back top and bottom engine frame mounts are properly done up tight :grin2:


PS I had this on my Mk1 after 19,000 miles as the bottom mount had become loose over time.:frown2:
Tightened with a long bar extension and was there was no more trouble :wink2:

shudder happens at higher rpm and with increased load/two up. could be a lot of things, but could be lack of power due to fueling issue, air intake issue, combustion issue. i always try to rule out basics first. tighten engine bolts, clean airbox/air filter, change spark plugs, fresh gas, oil/filter change, tires balanced/wheels aligned, forks aligned. water in gas, use drying agent. fork oscillation happens at higher speeds too. then move up to from there to more complicated issues.

RPM's would obviously go up if the clutch was slipping... Beside loose motor mount bolts, make sure your chain's tension doesn't vary too much as you rotate rear wheel due to an unevenly stretched chain.

if rear wheel shaking, add rear wheel hub rubber vibration dampers damaged.

Hey Guys, Just an update. A technician finally figured it out. It was worn rubber engine mountings/ dampers. Don’t know how or why it failed so soon.

The newer Versys 650's are made in Thailand, with parts perhaps sourced from China... Their rubber quality may not be up to over 4 years of extreme temperature rigors in Africa, with salty seashore air. My 2007 was made in Japan.

Interesting that the item added to prevent vibration was the thing that caused it.
Are they able to be replaced by the owner or do you have to have the dealer do it?
Does the engine have to be removed?

I had to cover the cost of replacement. The engine had to come out cost me +- 9 hours of labor + parts. To add insult to injury they didn't tighten my radiator hose clamp, leaked all the fluid out. Left me stranded in a very dodgy area. One of our Lady bikers here was robbed and killed 3 weeks ago in the same area:frown2: but that is a story for another time.

Had to use Toyota long life coolant which is all I had at home. Think it will be a problem?

Makes sense. Only the thing is the vibes are so heavy now cant see out my mirrors. Hope it settles after a few mile.

Grab an inspection mirror and a bright flashlight. Then have a good look at the engine mounts from multiple angles. I've read that it is possible to have the engine sitting crooked in the frame, which can result in the engine case touching the frame and producing the vibrations you describe.

Good luck!
