Hi


Hi my name is Stephen,
I came to seek knowledge and share what I know.

Hi Steve,
Make yourself at home, but everyone seems to have gone quiet lately. So maybe you'd better say something controversial to wake everybody up

I is always loitering about Grazer; just a short hop from the workshop on my way to the coffee machine.... Just, of recent, nobody answers my questions..... :(

BTW hi Steve, and welcome..... grab a coffee?? LOL

You'll be amused to know that my current spare time project (and hence very slow...) is to write a simulation program to model the effect of comp, mid & rebound damping, with each piston valve combination allowing adjustable bleed, shim stiffness, shim preload and port size.

The idea is to ulimately put it together with a simple 2-body model of a bike (ie wheel and sprung mass), then feed it standard inputs like bumps, sudden brake applications...

It won't be useful for designing actual shim stacks or pistons, but it should allow "what if" testing of different philosophies, ie stiff comp soft mid, strongly preloaded mid, high-flow vs restricted valves...

Hmm.. inter esse-ing...

On a similar note; I had a Mille R (04) in the other day - only had it a few hours but - and apart from the fork revalve and re-spring, I needed to adjust the adjustable triangles on the linkage under the Ohlins...



Anyhows, due to the lack of time, I had to do it by feel... and prior knowledge of the Ohlins' internals gives one a head start when it comes to feeling more or less progression in the linkage ;)

In any case, I can more than likely get my mitts on the bike again so as to measure all the points properly, including the amounts that the bolts are able to be moved forward and aft at both adjustment points.

It would of course be very useful and save a lot of time, and especially when one does not have sufficient time in order to model from plastic, to have a program to ascertain where and by how much to move said bolts. Naturally, all of the above depends somewhat on fore knowledge of the valving characteristics of the particular shock - but at least it would be something to work with!!!

Something for the RRs would be superb!! Let alone the new R6s that I have my eye on for next year!!! The cast ally rockers are not so easily, nor rapidly, fabricated. having the ability to plan the item prior to producing a copy would be most useful to understate it all....
