One thing that might improve things is try balancing the TB's at 4,000rpm. There should be a good link somewhere on this site re a couple of guy's in America who are really into boxers and are pretty good at servicing them to get the best from the engine. They recommend doing an initial twinmax adjustment in the garage at the usual 3,000rpm and then doing a final tweek when the bike is on the move and running at a steady 4,000rpm in top which equates to about 70-75mph. It makes sense although I have never tried it myself.

Well Scotty if you can ride an S at a constant 4000 ajust the TwinMax and then lock off the nut on the cable all at the same time,tell me when your going to try and i'll pay good money to watch!!!!!
It's a bloody nightmare with two people,a quater of a flat on the locker will take the needle a mile past the center

Heh up Winger. I have enough difficulty doing the stationary adjustment !
They obviously stopped when they were carrying out the adjustment via the lock nut etc but managed to get a reading on a long quiet bit of road riding along at 4,000rpm. I suppose they could see if the needle was pulling one way or the other. I don't fancy it but they swear it makes a difference to the smoothness of the engine at normal running speeds.

Done it
Well balanced them at 4000rpm and then ridden with twinmax attached to check still in balance.
Unfortunately it made no difference to the vibes at all..

I've wrapped foam around the throttle grips with duck tape over that.
Just got back from first ride and I think there may be an improvement.

Will let you know after a few more miles.

You steer a bike through the foot pegs!!! you've zero input with your instep on e'm.
I'm sure "count steer " would disagree

Never mind Keith Code I steer mine wi me bum. I was always a little weird that way??!!
As for the vibes...In Spain I can generally ride through them and keep clear. But In my recent trip to the UK... the dreaded dead fingers got me again..... A THOUGHT. The balance weights at the end of the handle bars (very heavy) I am sure are "tuned" to reduce this strange "harmonic"... What if you were to change the weight... possibly increasing it... would that help... are there any experts out there???

Not that old chestnut again.
My six pack and thighs have never been so toned. If I try to hold the bars any lighter I would have to let go. Which I often do to get the feeling back in my hands.

11pm: Just rode 25mls home from work and the vibes were not as bad as usual (still not great). I think there may be something in this ambient temperature idea.

I agree, anyone who thinks he is steering with anything other than countersteering, is at the very least disconnected with the mechanics of riding a bike.
And for those thinking the only way to ride is with the balls of your feet on the pegs, please have a look next time you watch MotoGP. They are ride with their arches on the pegs. Only in turns they put the inside boot with the balls of their feet on pegs, not for control, but to keep their foot getting squashed between bike and track surface. And they ride quite a bit faster than we will ever be able to and would just about anything for more control and speed.
Then again, whatever feels good for you is the only thing that really matters. Just don't go deluding yourself saying it gives more control.

Ade..... I have been riding for a lot of years now... and do not grip hard.... any lighter and i would fall off... In fact (see previous thread) I used a throttle rocker and still got numb fingers.. It is just a function of being a twin.
Does the "balance" shaft in the 1200s make a difference????
Ditto Throttlemeister..... Although I think "A twist of the wrist" was atypical american publication and a bit posy..... countersteering is waht we do. I don't know about you but I just rode instictively since I was 16. It's only when you analyse these things you realise what is going on... but I am not a racer and need that extra 3 degrees of lean etc etc etc so I will stick to my instinct. Hopefully I will not then get into too much trouble??!!

You are right on TOTW, I very much prefer "Sportriding Techniques" from Nick Ienatsch if you are into reading. Much easier to read and doesn't treat the reader as an idiot.
I too just rode instinctively, and still do. But I also have a nasty habit of wanting to understand what is going on when I do things and why. And what I can do to make myself better.
As far as trouble, I think trusting what your feel and instincts often prevents you getting into trouble in the first place. Analyzing and training your skills allows you to get out of trouble when you do get into some.

You're obviously not holding on quite tight enough then.
Perhaps actually twisting the wrist might also help?
