Thank you very very much for your praise, I am extremely satisfied with the weekend and will probably need a week or two to process everything that has happened.

I will make a youtube movie with the bike runs and write up a summary later this coming week, there is also a documentary tv team coming from Germany two weeks from now so I need to clean up the bike and fit regular tyres before that.

Cheers from one tired Anders!

I just got back home and took the first shower since Wednesday. Tired as hell and just as happy, top notch weekend!!!

Here is yesterdays run, notice the very nervous steering when the front wheel hit the ground after being airborne a couple of times.

     Anders, It looked like you clipped a course marker at the end. Any damage?

Congratulations!  Could some of the instability in the front end be caused by the studding pattern?

Awesome, personal record in the second go, not a lot of folks come out that way! Now considering the frontal area of your bike and the drag caused by the studs and the ice (which is probably something you could elaborate a bit more on), the big question is - What kind of horsepower does it make? Is there a way to make a (reliable) guess/estimate?  :evil:

Cheers,
Greg

How stiff is your steering damper set?  How tight are you gripping the bars??

Anders............Nice Ride :-) :-) :-)

The spikes on the rear seem to keep you very stable. When you add power and the front light-weights, the front spikes may be too long and the bike is rolling on 'spires' rather than the tire. Shorter spikes or screw-heads may help.

Speed wobbles that I have encountered have been when the front end gets lights and then comes back in contact with the ground albeit slightly out of perfect alignment.  The design of the front end (rake/trail) naturally causes it to realign itself but may in fact over correct due to the momentum of the parts, setting up an oscillating motion.  In videos of the early British bikes, you can actually see one fork leg moving independently from the other - - very bad!  Newer front ends like yours are much stiffer and help but the steering damper is there to prevent the oscillations from continuing.  From earlier photos of your front end, it looks like your steering damper is connected very close to the centerline of the headstock.  It might help to make an clamp that will allow you to attach the end further away from the center which will make it more effective.  This should not be a problem for the travel of the damper because you have probably reduced the steering lock-to-lock rotation to a minimum.

Looks like there is also a crack/groove in the ice that upsets the stability a bit. I have never ridden at high speed (over 120) on a bike, so I am not offering advice from that perspective. I have however encountered many (MANY) ruts, roots, logs...that have caused me some handling issues. If you watch the video back there appears to be a groove that is giving him some issues each time he crosses it.

As for the dampeners, spike length or other characteristics imparted by their existence or lack there of I am learning by reading here.

Anyhow, nice job Anders. Looks like you and the bike are in good enough shape to try it again. Well done!!!!
