Tingly Fingers

i,ve fitted a wunderlich brace across the bars to see if would stop any "tuning fork" effect, but it made no difference.
so i filled the bars with lead shot ( local dive shop ) got nearly a kilo in. i took the bar ends off and poured it in from both ends, let it settle, then topped it up.
sadly, this has still not solved the vibes.
thought about unbolting the bar clamps from the top yoke and maybe trying different packing, like some rubber washers. has anyone else thought of this? does anyone think this might be a bad idea?
 
Rox Risers

I've got the Rox Risers fitted now (see pic in earlier post).

They are the anti vibration ones and they work an absolute treat.... but... I've had to move the brake lever along the bars by about an inch and the brake line is still quite tight so I am looking at having a bit of braided hose made up to compensate. The clutch cable is also quite tight so I am looking to re-route this - which all sounds like a bit of dicking around but the extra height and adjustability is worth it I think.

Did a fair few miles over the weekend and no tingly fingers.
 
A suggestion ....

I've been getting tingly fingers on my right hand only riding my new 650GS (with Barkbusters so not the original bar-end weights) and read all the posts on this thread looking for a solution (I'm using exactly the same gloves as I had been on the 1200GS so it's not tight gloves.) Most of the solutions sounded fairly drastic (lead shot in the bars ... ) and I wondered whether the lead tape that is used to vary the balance of tennis raquets and golf clubs might do the trick so I bought some cheaply on ebay. I wrapped several turns round both bar-end weights and the current setup, with slightly more tape on the right bar-end seems to have solved the problem (so far). There is still vibration but not enough to cause dead-finger which had occurred before.

This is so frustrating. This bike had so much promise, the Holy Grail for trail riders, light and small enough to go off road. Enough power and speed to keep up with the litre plus boys. Good fuel economy and range for touring. Good looking and handling bike that will thrash commute and tour with excellence. For a one up rider it is the best bike in the world.
But the thorn in its side is the unbearable vibration. Off road is fine. A quick thrash is great. Or a long gentle tour. But if you keep it over five thousand revs for more than 30 – 40 minutes your flaming hands will fall off.
I have tried cross bracing, filling the bars with lead, hand guards on – hand guards off, even taking off the bar clamps and trying different washers/packing. New tyres, re-balancing, different gloves. All to no avail.
I still have the bike, but I do not know for how long.
The moral of this story….
Never ever ever….buy a parallel twin. The wobbly brake reservoir I noticed on the test ride should have been a giveaway. Instead of buying a solid washer off ebay I should have twigged.
If only they’d put a 90 degree v twin in.
Well, better to have loved and lost I suppose.
 
My F8 seems fine to me even after 8 hours (not the seat though). Why do/would some vibrate more than others?
 
This phenomena can often be caused by pressure on the ulna nerve in the base of your palm. This will be made worse by vibration but try playing with bar and lever angles to try and take the pressure off your hands.

This may be why risers make a difference for some.

I used to suffer from this mountain biking even with suspension forks (lot more weight on your hands/wrists) and cured that by getting Specialized Body Geometry Gloves, that have a gel pad that sits over the nerve, so gloves too can make a real difference. Check out these gloves, although not designed for motorcycling they look as if they offer pretty good protection.

I have only had my 800 a day so too early to tell (and a 4000 rev limit) but I had a really long demo ride last weekend and did suffer from a bit of tingling. However this was almost certainly due to being tense, so once I realised and relaxed on the bike, it soon went away.
 
this works for me

If you sat in a chair for hours with out moving you would also get cramp, pains and stiff joints!

when on long trips i try to stand up every now and then and give my body a shakedown. ref my wrists. firstly dont hang on so tight and secondly get into the habbit of flexing each finger and rotating the wrist every now and then. circulation of blood does wonders,
when its realy cold try a neoprene wrist brace.
Lastly on my ktm 640 adv i used dense foam rally grips and the ktm realy did have vibes. may be a bit hard with heated grips though.

ok thats my pennies worth!
 
I get a pins-and-needles sensation in my right thumb and index finger. I have now found that i get the same sensation when i use a elliptical trainer at the gym. I have an appointment at the doc to help identify if there is an issue
 
Like a few others, i use a Wunderlich Throttle Rocker. Great bit of kit for under a tenner (a year ago anyway). Can ride for hours without tingly fingers.
 
Cricket Bat Grips

I don't like the standard GS grips ... too small for my "manhands". The other day it occurred to me that if I cut two 10cm lengths of the right sort of grip, heated them in hot water, sprayed the existing grip with windex and slipped the grip section over the old grips, my problems might be solved.

Imagine my surprise when 10 minutes later this was exactly the case!

I am now much more comfortable, less wrist ache, almost no tingling vibes through the handlebars, and as an unexpected bonus ... much better throttle control. All this for AUS$4.95 ... I'm still shocked (also a bit worried that I may experience a strange attraction to KLR650's ... their riders always seem to love Cheep, Cheep, Cheep!)
 
I suffered numb fingers in my right hand and tingly in the left whilst on a long trip quite recently. I assumed this was because of the length of time I was in the saddle - running until the fuel light came on - and on the motorway compared to my normal runs around the countryside.
I eventually traced the problem to my handle bar mounted (near the LH mirror) Sat Nav not being done up really tight on the Ram ball.
Might be worth checking everything is done up tight on the handlebars??
 
i get the tingly digits too.
maybe worth a search on "white knuckle disease" or "Reynauds syndrome" :nenau

ANYhow,
the right gloves, messing with 'bars and lever set up and mostly - foam handgrips helps me. :thumb2
 
As it stands the F650GS is better for high-speed cruising as the gearing is higher. With my F650GS coupled with R1200GS handguards, handlebar risers and a crampbuster I rarely suffer, even on a 980-mile/24 hour endurance.

It's a pity BMW chose to deploy the close ratio gearbox from the F800S/ST on the F650/800GS. With six ratios to choose from we could have had both lower first/second gears and higher fifth/sixth gears.
 
Tingle fingers etc. In the Enduro world it is a well known trick to fill the bars with silicon mastic or similar. This kills the problem dead. Make sure that if you have stock bars there is often a small locater hole in them under the switch gear. If you block this or tape it over then you are ready. Get some fuel pipe and attach to end of a silicon cartridge. Push pipe into bars until it reaches the other end and then back fill the bars until you can see the silicon from the open end of the bars. Pulling the tube slowly outwards as you inject the silicon makes this job much easier and far less pressure is needed to fill the bars. On KTM thumpers this is the Magura solution. Even works on the old 640 ADV:augie:D
