A shorter dogbone concern:
When I was hassling with my shock I tried the (15mm) shorter dogbone from Koubalink (fits the Funduro). I assembled the links on the bike without the shock to see how they would work. I was alarmed at he angle that is created by the dogbones and the shock carrier link - it was almost flat at full compression. (Needs a picture) This has got to put some serious stress on the mounts and the links/bearings - I feared that it would tear the mounts off of the swingarm if you took a big hit at the rear. On the positive side, it increases the wheel to shock travel ratio (more wheel travel for the same shock stroke)

Bmac - that shock looks good - pity about the delay and to and fro with Klaus. Let us know how it feels. He set mine up for a 80kg rider w/gear, and I find it a little hard.

The ratio is 3.5:1 for figuring height addition on a Dakar or F650. Wouldn't a 15mm change raise the rear about 50mm/2" ?

HH's links are only 7.5mm/1'' raise. I love mine and have no worries that it will create any ill effects. I rode the crap out of mine last weekend and they performed flawlessly. I'll be out again tomorrow night for an all nighter in the ANF

I'd be more worried that the stock 8.8 bolt is going to break, than HH's raising links will destroy my swing arm.

I've been riding around on pretty much identical links to herrhelmets for a few months now, hell i did all the research along with jonkem

Mine don't have the same ammount of machine work around the holes as herr's but are otherwise identical.

Absolutly no issues at all, that includes a few 70mph + takeoffs over humpback bridges

btw i also tried the funduro koubalinks, notmybike was almost spot on, they give around a 2 1/2 inch lift. Way too much for the bike, the one inch lift link is only a few mm shorter than the oem link so it won't put too much stress on anything.

I was also hoping to see you incorporate the DL1000 shock like you originally planned. But that didn't work out either.

Not that it hadn't worked out, I just decided to ride my stock one into the ground first, which still hasn't happened.

Building my new Husa-style tank opens up pretty much any shock to me with the correct dimensions. I'll be doing the homework over the weekend and next week.

Thanks RC, and again for doing the R&D. I owe you a favor

Dude, it's 2010.

The reason why you're an asshole is that you decided she wanted hard luggage instead og nimble sexy Ortlieb soft ones

Just finished reading the 1665 posts.. again..
As this is my first post, id like to say cheers for the mountains of information here, it sure has made this project a lot easier.

Currently I have a set of yz426 (2001) forks (new oil rings/dust seals and bushes but original springs) with triples, along with an answer low bend protaper bar and 15mm bar adapter/raiser.

Gone with the original beak (well pre-loved), and on with the cycra fender. Credit to Soloyosh for the idea.

Now perhaps with a little more clearance.


As for the hanger, i went for the JohnAero style and decided fabricate it with 3mm steel plate


And that did take one or two attempts between the furnace and the stamp


Drilled and tapped


Cleaned

And finally assembled:

and its not rust, its just reflections from that real shiny por15

and as you might be able to tell, its a weekend affair
But the end result looks the part

However, having said all that.. I hear Rad has some extras on the shelf I'd be real happy to deprive him of!

If anyones still reading this thread...

My personal findings now that it's a 100% sorted front end.

A little caution for any inmates going down the YZ route and getting the fork internals re-worked to suit the bmw. When you spec the springs for your new forks think long and hard beforehand about what your going to be doing with the bike and how it's going to be loaded.

Don't forget that you'll need springs that can do a good job when there's just you on the bike without luggage and a passenger.

I've gone too hard on the lighter end of the progressive springs which isn't too good for stability when the bikes at it's lightest. Richard at HOH has done a fantastic job on the internals and the bike is a dream when fully loaded (or even overloaded ) but if I did this again i'd sacrifice some weight capacity rather than stability at speed when unloaded.

If you don't drive fast, go strong on the spring it's pointy & positive but remember you'll be sitting very upright at speed and that'll lift the front even more

i went with what richard at hoh recommended, .48 to .56 which was pretty damn good from the outset. I have since added 12mm of preload as the start of the spring seemed just a tad to soft, it's on the money now, carving up corners like nobody's business i can easily carry 5 - 10mph more into a corner just because of the confidence i have in the front end now.

Works just fine with luggage too.

.48 to .56 would probably have been better for me as I haven't spent quite as much on heavyweight TT farkles as RC

Are we talkin' dirt or street cornering, or both?

hell, i'm in the uk, road riding it is.

very few places to go off road in this country now, and when you do speeds are usually low due to 'ramblers'
