I have to get the damn bolt out first.

Moving up to a 4lb hammer tonight.

I had a breaker bar on it last night. It WILL NOT TURN!!
I sprayed WD40 everywhere I could. Hopefully that somehow makes a difference.

Its a good thing the jerry can for the lawn mower is empty. Otherwise bonfire at my place!!!
2 nights on 1 bolt is just not on.

Rant off

What length of springs have yall used? I will probably order race tech or progressive custom springs but need to know the size, including the shortening... Thanks!

Depends on which forks you are setting up

YZ 46mm have a 460mm spring so reduce that by the size of your shortening spacer
YZ 48mm have a 479mm spring so reduce that by the size of your shortening spacer

Here is a link to the Kayaba EU parts list with dimensions for most parts http://www.technical-touch.com/index.php?id=downloads

Use nylon spacers in between the fender and the underside of the triple, on the rear bolts. Might take some experimentation to find the correct size.

Great, thanks! and if I have read correctly, for a conversion on the Dakar (not standard gs) the shortening will be by 25mm. And I will need 25mm spacer. Correct?

I wound up relocating it again to inside the headlight cowling. Found a spare holt in the metal subframe (big metal bowl bottom). Mounted it on the left. It definitely is loud in there. It seems ring for sure.

Now I have two horns. One looks to be the stock one and the other is off my GSXR750 I think. Took it off when i coverted it to a trackbike. The bi-tone seems to make it much loudder.

One of these might help...

If my supermoto fender lets too much mud and much get to the radiator I might bolt one of these on or hack off the old one from the BMW fender and use that. We'll see.

According to this guy on SMJ: "I used a piece of 3/4" and 1/2" CPVC pipe and cut them to the length I wanted to lower my front end." That's two separate pieces, one inside the other, pic shows a length of 3 inches, here's the link to the (well written) post:

From http://www.f650gs.crossroadz.com.au/ForkUpgrades.html

Code:
                          GS      Dakar  YZ Forks
Fork Travel or Stroke   170 mm   210 mm   280 mm
you would need to shorten by 70mm (just under 3 inches).

I shortened mine one inch-- 25.4 mm. According to the best measurements I could the Yamaha forks are 35 mm longer. But the Ohlins shock puts it just a tad taller.

It worked a treat.

Maybe I'm not sure what Marisa is asking here, but I think she'd should be concerned about this:

GS Dakar YZ Forks
Length - Top of upper yoke to axle center

GS 825 mm
Dakar 890 mm
YZ 925 mm

If the static sag is set up properly on both forks, I think distance of top yoke to centre of axle is the key, no?
