DR750 & DR800 owners thread

[Jakob]

can anyone please put an instruction how to change fork oil.. and how much oil goes inside it, and how to do it without breaking those oil seals or whatever they are..
I'll just grab another beer and do what I know how to do until someone helps me out.

Jakob,

I do this like in the service manual described.

http://www.timguy.net/sites/drbiginfo/DrBIGmanuals/

Additionaly I use petroleum to get the black stinky old oil out of the bottom valves.
I let them drip out bottom side up overnight (after petroleum flush).
Fresh oil depends on your and your bikes weight and preferences.

Refill: press the fork together, spring not yet inserted.
Fill oil up to 160mm (SR43, Wirth springs, rider app.100kgs).
As a rule of thumb: The smaller the air chamber the harder the fork

Cheers,
Lars

Hi! Does anyone know if it is possible to change the clutch seal (red) by undoing the blue-circled bolt and pulling out the axle, or if you have to do it the hard way? Thanks!

Yep, I'll do it this way, too.

Fill oil up to 160mm

Whatever oil or level you use....make certain to pump the forks up and down a few times to expel all air bubbles. You'll see the level get much lower after the air is gone....then refill to final measurement.

[Resi]

Right!

[the_sad_punk]

And.....with progressives springs tighter wound part rides up top.

[bluesman]

Interesting. Why tighter part up top?
I mean - it is how I usually install them too, but did you find any tips on why we do it so?
We recently had big discussion on this on our site, hence the question...I had theory on that but it's kinda...shabby...

[robmoto]

Probably so the tight coils don,t take up to much oil space.
Blue have you got the Tiger XC pic,s required and a full report nothing less .

[Resi]

Maybe the unsprung masses are lower?

Lars

Yep, those are the two reasons. For our riding #1 makes the most sense. If you're a racer (or a real techno-weenie) #2 has some validity.

I've also heard this: As the spring compresses, the more tightly woundd coils will coil-bind first.....this makes the coil-bound area go into a slight "S" shape and so the overall diameter of this area grows.....This growth is better handled by the fork if it happens in the top (tube area on "conventional" forks) than if it happens in the fork leg. If the spring contacts anything up top it will be only the steel tube rather than softer aluminium parts down below......Dunno if I believe this one or not.

In the end.......the spring doesn't care.

All the bits are now on ebay

Hello guys,
a friend of mine, running a professional motorcycle-workshop, once told me, that the narrow part of the spring creates too much foam in the fork-oil if it's installed on the low-side. Sounds not too stupid to me ...
Kind regards, Bambi
