Sure, its like shooting fish in a barrel some times, but thats fun too right?




Hey Pyndon,

This has been a great thread over the years. Thanks for that, and i hope you keep it up.

If you need a place to crash in France, give me a shout.

Hello Pyndon! Your absolutly right about how fast a modern adventure bike can be. I use my 990 when instructing "road-riders" driving skills. I'm on stock Scorpions, but it's very seldom I can't hang on. And I'm just an old fart who have never raced a single lap. But some years of training does a lot more to speed than the differing between a Duc 1098s and a 990.
Something els; may I ask what your relationship with Rizla Suzuki are? Are you wrenching for a certain mister Sykes?

I killed it!!

So, I took the bike on another track day yesterday.

All was going well but I was struggling with the setup on the rear end. Upon changing direction quickly from left to right I was suffering a little 'chatter'. The bike is pretty well dialed in so this was unusual.

I thought it might just be the surface of the track so I tried a few clicker adjustments but it didn't help.

"Either I have forgotten how to set up my suspension or I'm loosing my marbles" I thinks to myself.

Click-click, ride, click click, ride, still no better.

So I rode.....




......and it rained........so I rode some more.........



As the day went on and the track dried out, the chatter was more pronounced, sending the rear end juddering sideways in a completely uncontrollable fashion.

Having never had a problem with the setup of the 950, I was a little bewildered to say the least. Never the less, I just rode around it and figured I'd strip the shock and check it out on my return.

......I rode some more......

After washing the bike after getting home, I decided to strip the rear shock out to see what was going on.

On doing so....






Not good.....! Not 1, not 2, not 3 but 4 severe cracks in the swing arm.



I marked then with a pen to help identify....



Since the shock is mounted on the left side of the swing arm, this identifies why the chatter was more so on the right side. Armed with this knowledge, needless to say I'm no longer persuing the shock re-build.......

Anyone got a swing arm they can let me have cheap??

Pyn

It's funny what you ride around - I've heard the same sort of "I just rode around it..." to all sorts of stuff like this, from cracked forks on moutinbikes to wheelbearings going south to dragging brakes.

This one could have been quite hazardous, though - glad you caught it now.

Wonder how long before it would've let go......FRIGHTENING!

Certainly worth ckecking them for you guys that ride hard.

I don't think those Whoops helped in Baja with all the luggage on!

Yeah..., I dont think thats going to buff out...

There was a 2003 swingarm on ebay for ages - dont know if its still there.
It was being sold by Blacks Bikeshop. They periodically relist the stuff they have left - so hard to know if its still available.
http://stores.ebay.co.uk/BLACKS-BIKESHOP-LTD

Oh, and if you find one thats got the drain-holes already drilled, and a sidi decal on the side.... uhm, Let me know (probably off my stolen bike!)

That's scary!
Do you have any idea on what has caused these cracks? I had a
fracture line in the swing arm of my BMW after bottoming out very heavy
while going through a pothole.
Could it be corrosion from the inside because of water in the swing arm?

The TDBR SE should get a thorough inspection, pronto! I lost count of how many times I bottomed that thing, and the one boobytrap I hit launched the bike and I so high I thought the swingarm was going to break right then and there...

I have heard of the pivots cracking but not the castings there where your failed.

It will be interesting to cut it up later - cross-sections of cracks are sometimes even more frightening, not to mention you might find more - cracks always start at a surface, and not necc. from the "outside" of a welded assembly.

Typing this much sucks on a BlackBerry...

Send it to the factory with a letter saying "Do you really think we're going to believe that Meoni won the Dakar with such a poor swingarm ?! That's crap !"

Yep.....that one I can answer!

45,000 miles of hardcore Pyndon abuse. Pre-running the Baja 1000 last year probably did not help (Neduro will vouch for that!).

Oh, and sticking wide rims on with sticky tyres and hooning around like a lunatic probably has not helped much.

Am I bothered?? Absolutely not, this bike has been a bomb, I will find another one, bang it on and go for thousands more miles.

I love this bike.....

Thinking about that swingarm again I wonder if it has anything to do with the fact that the early torque was 110nm and later got revised to 95nm....
too tight?

Nonsense, Pyndon, we rode like little old ladies down there, smooth and straight the whole way.

FWIW, I believe the early swingarms were well known for this, I can think of several folks off the bat that have had this happen. The new swingarms (not sure when they changed, but if you look at the SE or a 990 they are very different) seem to have fixed the issue, so you might find one of those to retrofit.

Wonder if Curtis has one sitting around from his various projects?
