Ok so a major electrical crisis happened today. 2011 DR. The license plate light ground and power wires came loose and touched while the bike was running and burned up a bunch wiring. The bike died before i could shut it off. No battery power now. The 30a fuse blew so I replaced that but still no power. The battery terminals are fine and the wiring coating is all burned up but the wires still look ok. I hope the fuses protected the battery from the short but I don't know. I didn't have time to really dig around as I was late and had to jump in my car but tomorrow night I will get some pictures up and hopefully have a clearer idea of what's wrong. Since every problem with a DR had been fixed on this thread I thought I'd post up and see if you fellow inmates can give me some target areas to focus on. I would love to get this fixed myself with some handiwork and electrical tape. I have disconnected the license plate light wiring from the harness but the short went up past that. Ayudame!

That's where I'd place my bet. Any idea what condition your cush rubbers are in? I know that when I replaced mine with about 30,000km on the bike it made a noticeable difference towards smoothing out the ride while cruising on the hwy.

I've fallen back in love with the DR. Maybe I will pull it off the market....

Seems odd that I can't sell it for 15% below book value in Montana, land of the fireroad......

WOW! You wore out your rear rotor in about 6,000 less miles (doing the conversion for the U.S. readers) than I wore out my OEM brake pads! I still had 3/32" left on my OEM brake pads and minimal rotor wear at almost 15,000 miles, when I replaced the pads.

You must spend most of your mileage off-road going downhill? My mileage is almost entirely on-road, mostly up/down foothills roads, so mostly front brake use.

I replaced my front OEM pads at 9,100 miles, rotor looked as-new.

I wonder if you fixed a fitment problem when you replaced the rotor. My KLR went through a set of rear pads surprisingly quickly; on inspection I found the brake pad backing plates binding in the caliper, had to hog out the mounting holes a bit.

I've got about 30,000 kms on mine now and works well. Seems to be wearing heaps better than the stock one which was trashed at about 15,000 kms

Click 'Edit' on the bottom right of your post. Click 'Go Advanced' on the edit page, still at the bottom right.

Now below the edit window is a row of smilies, you'll see has been clicked. Unclick the button. Don't forget to edit out the rest of the title above the edit window. <--Don't know how he got up here, can't get rid of him

Dunno why. I got the bike with 11,000 kms and pulled it apart and reassembled to my specs, ie lube everything and torque to spec etc etc and learn the bike. It came with stock pads that were junk so fitted EBC sintered at the time. A couple more sets since, and the stock disc as above. I do tend to use the rear brake a lot, but not so much down hills, the front is much better for that. I'm a rear brake dragger by nature. When I used to do lots of kms at Philip Island and Eastern Creek as a trainer/coach and ride day marshall I'd trash a set of rear pads in less than 1,000 kms on my ZX9R, ie 2 track days.

Dragging the rear brake gently in long corners with power on helps stabilise the bike and maintain drive. Also good in sand to slow down without loading the front to help tip in. Not so important on the low power DR650, but its how I ride. Defintely helps on my road bike, and FE650 Berg too. Slow down with front brake first, then rear brake, then as tipping in, ease front, but maintain rear. Open throttle at apex, or sooner, and release rear brake against throttle to manage drive on exit with brake balanced against throttle.

Mud. I'm guessing Berg's DR has seen a lot of mud riding. Mud is Hell on pads and rotors. Eats them up fast. I'd also bet he drags his rear brake a lot, as many off road racers do. (myself included)

I'm still on original rear rotor ... but I haven't measured it. It's most likely worn out. But so what? Just means it gets hot sooner. If it was warped, I'd change it. It's straight and true. I've only ridden a couple hundred miles in mud. I hate it.

I like the look of that Aussie Ebay one. Good price too.

I'll snap a picture of mine tomorrow.
I bought the DR in Salt Lake City from a guy that had it jetted and tuned for the SLC elevation. Now that I moved to Houston I need to learn what needs to be done to make it run as is should at sea level...

BadDogMax's post explained my issues exactly, so I joined in with my trouble shooting. You may have been talking to him, since he posted the video.

I'm not trying to cut in, but I'll add this: I'm an admitted short shifter. But this problem never occurred in the first 22,000 miles. There was no hint of this vibration. It started slowly after replacing the chain with a new EK. After a few thousand miles of that, I put on a new DID. The problem, although lighter at first, has continued. Both chains had/have a riveted master link, done slowly with many digital caliper checks while pressing on the side plate.

Analogy: when someone attacks your swingarm pivot with a jack hammer while riding, you'll know right away 'that ain't right'.

Both rear wheel bearings and the cush hub bearing are new (twice during this) and the hub cushions are also new. Both had zero impact on the problem.
Back to our regular programming.

I'm guessing lugging the engine, also. Both my DR650 have made a simular noise when running constant speed at low RPM's. New/good chain or not.

I've replaced the cush rubbers before on another bike, and these are as tight as new I'd say... the sprocket won't fall out when the wheel is tilted, it's tight in there.

The sprocket carrier has almost zero wiggle. Besides, wouldn't a loose bearing lead to side to side chain oscillation, not up down?

The bike has 4000 miles, has always been garaged, and the chain /cleaned lubed after every other ride. I checked for stiff links and didn't find any.

I'm voting for a resonance/oscillation like the Tacoma Narrows bridge disaster we were shown in physics class :

Chain vibration video

I'll add that the video was taken while accelerating from 50-60MPH in 5th gear, with a 14t front sprocket. Not lugging it IMO.

I appreciate all the help and theories... maybe we can solve this thing!

Does it do it with the 15t?

My TT350 does it more with the 14 than 15. Although I think that's just because the chain is closer to the slider.

If you have either very loose, or tight links, it can accentuate the slapping.
