I've got the parts in, front end off, steering stem & lower triple off & working on drilling the security bolts. Those things are a bit of a PITA do far. Lol!! Once those are off & I install the new races in good to go. Need to get a heat gun & some new drill bits this week.

I'm planning to drill & tap the stops on the YZ lower triple for mine once I get them on the bike w/ the bars. Then use a steel bolt to adjust them. Pretty sure someone did a write up on it somewhere.

You can look at a summary graph with various models here http://www.f650gs.crossroadz.com.au/...tVspringKG.pdf
I finally got around to looking at the chart. Maybe I'm a bit color blind but it's hard to tell the YZ426 from 640ADV on the chart. Either way at about 180 + bike at ~425 = 605 or 275 kg. The chart puts it right at .50 to .55 depending on bike/forks. The difference from bike to bike would be different forks & different valving.

I am just about done machining a prototype ignition switch mount that I am planning to send to Wayne down under. I was hoping there might be someone in Florida, perhaps near Kissimmee, who would take a look at the mount before I send it.

If it passes muster I will be offering it at $35.00 plus shipping.

I think the reality with these forks is a spring rate in the .6's is more likely needed.

With luggage and gear and the extra weight of the bike and rider, I would be shocked if .55 would be satisfactory unless one were really a lightweight.

I am not, and the suspension work I had done-- YZ 450 fork and Ohlins shock install complete-- is fantastic. I can rail into parking blocks or curbs without letting off or standing up, and the bike tracks like it's on rails. The BMW tech (who raced Baja a few years ago) rode it and compared it to his Dakar with Ohlins forks (leftovers from the Cannondale collapse) and very impressed.

my spring rate is .70, shortened 30mm (very close to stock Dakar for length) with a heavy Ohlins spring fitted for the shock. Keep in mind I am a heavy rider and will be travelling loaded for camping with all the panniers, racks, guards, etc that entails. The springs were custom made by the local suspension wizards here, but any quality suspension shop will have the ability to order you a custom set of springs.


The only hiccup to the install was my attempt to install wider Renthal bars and Acerbis handguards. No es bueno. The wider bars are great but they already took a lot of the available slack in the clutch and throttle cables, the electrical wires and brake line. When installing the Acerbis guards they smashed dead into the speedo and tach well before I ever reached full lock. I have very little additional room for bar risers. This is how people get around the problem of crushing their instruments-- bar risers. You will need a longer brake line at least.

I also installed a Touratech skid plate with storage, which requires one to disable the sidestand switch. When I was finished everything worked great aside from the neutral switch (which has always been wonky) is now on at all times.

I'll have dig in and see what I might have pinched. I don't know that the sidestand switch and the neutral switch are connected but they could be.

this heavy:




That's me in Churchill Falls, Newfoundland. That's a size 54 Darien, size 44 Olympia Ranger pants. Size 14 Aerostich Combat Tourers. XXL Shoei Multitech

That's the Dakar in Churchill Falls:




The sharp eye will notice the right fork seal is blown in the above photo.

This is how I noticed it:



Where the hell did that oil on my right boot originate? From the fork.

I'm going to say 260 all kitted up.

I just used Yamaha seals and seal skinz neoprene seal covers.

I was told by my buddy whose kid races both a YZ125F and a 2-stroke YZ250 that I should plan on changing them once a season because that's all they get out of them.

I should also mention that on these forks you really need to make sure the left side (the nut side) of the axle is tight while the right side is still floating with the pinch bolts loose. Do not tighten up the right side pinch bolts until you've pumped the forks a few times so that the fork can attain it's natural position. Otherwise the forks are torqued and wear on the bushes and the seals is accelerated.

I'm hoping I can get the seals to go longer than once a season, I also hope the seal skinz work. I bought the long kit and simply cut them down to the size I thought was best.

Raising a Dakar?

I will ask this in the Dakar thread as well

Has anyone ever raised a the front end of Dakar using the OEM forks? If yes, how?

I have a 6ft plenty mate who makes a Dakar look small. He has asked for me to come up with an idea to raise the bike.
I know alternate forks are the best option. But costing is also a factor here. So trying to get as many options as possible.
