'91 DR650s

I have an opportunity to buy a '91, it looks nice, bone stock but it seems the rear shock has lost its seals/fluid 'cuz it bounces like a pogo stick. Same with the forks. Is the rear rebuildable or do I gotta buy one? Where? What? 600 bucks seems like a good deal but is it? Been riding a long time and have a KLR but thought for the money this would be a good project... Any insight would be greatly appreciated.

This forum is more for the 1996 and on DR650 which was a major face lift year for the bike.
There is a forum here in Thumpers for that earlier DR who will know better but you could always consider the later bike.

There is some good info in here, but its not worth the hassle of digging through the bitch fest.

The BS now covers the useful tech entirely.

Some forums refuse to feed trolls who do nothing than belittle other posters and argue just for spite. Not this one. Before long the DR650 won't even be the subject.

Nice pics ADV8! Youv'e got some incredible riding down there. Tell me something, do all you Aussies have the Safari tanks, simply because of massive expanses between fuel stations? Im starting to think Africa, Russia, and Australia are the only places that merit such capacity. Otherwise, having all the weight of a full tank is kind of a drag, no?

But you don't have to fill it every time, but when you do, 6-700 kms is handy for sure.

Not all of us. However, fuel load and the remote nature of things is always a concern. If I lived where ADV8 does I'd have the 30 litre tank. I'm building another DR which will have a 30 litre for that exact reason. I'm looking at rear tanks for it as well. I'm planning on a big trip and it is the weapon of choice simply because so much is available after market for it at cheap prices.

With the 18 litre tank, if I head out into the Western half of the State of NSW I get to the point where it's a full tank and I'm on reserve between fuel stops. I've rolled into Cobar a couple of times on fumes. Some of the back roads are lucky to get a couple of vehicles a day on them, so if you get stuck, you're really in the shit.

I've had to reduce speed on trips on the longer legs, to get better fuel consumption just so I could make the next fuel stop.

In the region I live, Service Stations are closing. Economic reality. So places I used to count on are either closed, or have limited hours on weekends. If I leave town on a Saturday, it's usually carrying enough fuel to do whatever round trip I have planned and end up back at home on Sunday. The high and low tourist seasons play a part too. Between summer and winter there's a lull, and they close shop for their annual break.

It's a hassle. But it's something you just plan for. On a trip, you may have to ring ahead and make sure places you're going have fuel. You can't always count on a remote fuel stop actually having fuel. Road closures due to rain etc can limit what supplies they get. Things can change over night too.

It's an even bigger hassle for more modern bikes. My F800GS doesn't like anything other than high octane. Finding High octane in remote areas isn't likely, so you carry octane booster.

At least a 30 litre tank for a DR is relatively cheap at around AUS $670~700. A 20 litre for the BMW costs AUS$2000. I think the target market has a lot to do with the price.

A lot of guys planning that "one off trip of a life time" buy a 30 litre fit it, use it, and sell it when done. Some keep them for the long trips and use smaller tanks for day to day.

To do things properly, you need to have the bike set up to account for the extra weight, or it will handle like a pig on tighter stuff with a full fuel load. It's ok once you've burned some fuel off, it's possibly better than a normal 18 or 20 litre tank because the weight is down lower for the same fuel load. If that makes sense. But if your springs are a little on the soft side now, they'll be a little bit worse with a full load.

For trail riding, I stick with the 18 because it allows me to complete a 280km loop and keep a reasonable reserve for when things go wrong. 280km doesn't sound far, but it can take almost all day depending on where I'm riding. It's predictable and I plan around it.

And this is not just theoretical, you can actually feel the weight of the WR: yes, it feels much lighter than the DR when you move it around, but when you sit on them they feel about equal in how they balance their weight.

In a sense, the DR's weight is less objectionable than the WR's given that the former is a 15-year old bike (and really, has its roots in the mid-'80s). What kind of an excuse can the WR offer?

The 525 EXC is in an entirely different league in that respect: despite the fact that it has to content with double the horsepower of the WR, it weighs 20 lbs less than the WR -- and you can actually feel that when you sit on it.

Indeed, I had seen the Freeride and huge bonus points to KTM for coming out with such a lightweight bike, but I don't think it's street legal. Plus, 24hp from a 350? That must be a negative record!

The old "cush drive bearing failure" hey Steve?

Single sided seal?

Makes you wonder what they were thinking.

I keep spare double sealed jobs in the toolbox.



What was the longest hop between fuel?

I agree you would think they could have made the WR lighter, it weighs about the same as my '99 DR350, one reason I'm still riding it! And although it wasn't street legal, I think about the same weight on my old TT500. All I want is a 450cc, 250 pound dual sport with a reliable, dependable, 40hp low maintenance motor and a well spaced 6-speed transmission. Just too much to ask for, I guess?

I thought I had read that the Freeride WOULD be street legal, but I guess we won't know for SURE until it shows up here, hopefully next year. And while the power is down at 24hp, with a weight of 220 it could be enough and hopefully the detuned 350cc motor has good power at lower RPMs and a nice wide power band! I'll bet there will be ways to get a little more power out if it too, since it's essentially a detuned makeover of the 45+ horsepower 350 exc-f.

50mpg by the way
Who's using a properly jetted standard BST? Pretty sure I mentioned waaay back that it was "controversially modified".

I found the Dynajet kit and the recommended jetting and settings to be an excellent improvement until the first time I filled the fuel tank.

Then I went back to the drawing board.

The only thing I used from the recommended parts was the needle.

I drilled out the hole in the slide, then drilled a second hole, cut 4 full turns off the slide spring, and then stretched it a tad to stop surging. Fitted a washable cotton filter to the vacuum relief for the carb slide.

It has a pod style air filter on it, with an adapter, so the filter is 55mm od at the carb end, and is 100mm long. Straight through muffler off a WR450 with the quiet insert thrown in the bin. WR pipe from the engine pipe joint pack.

Drilled the step out of the slide because after asking questions about it a huge thread war seemed to erupt over the way the Dynajet needle was supposed to sit. So I removed the step and adjusted the needle to compensate, which meant the needle no longer rubbed on the side of the emulsion tube.

I believe it has a 155 main, left the idle alone, used a Procycle extended mixture screw and just adjusted for strongest idle.

Best modification I made, run side by side against pumpers, very little discernible difference.

Spent the cost of a pumper, bought 2 brand new RMZ shocks off ebay, and bought 1 brand new RMZ front wheel.

Ka-ching!


52.3MPG 22.5km/l average.


Ba-zing!


warning: I may have had several double shots of coffee this morning. That's never good. But it's all fun and games. Educational too.

Yeah, the last one is replacing a cush drive bearing on the banks of the Darling at Wilcannia while we had lunch.

The bike was recently new to the rider, and it was his first big trip. I checked all the cush bearings most days, but forgot the night before, so while the puncture was being fixed on the other DR, I checked them again. 600 kms since checked, and about 2-3 mm lateral movement of the sprocket had developed in that time. Changed it 50 kms later on a nice concrete footpath. It was a double sealed All Balls or Moose, the ones with blue seals with no markings, and had seen some water, and no extra grease had been added. I doubt any bearing would have done much better. The wheel bearings weren't great either, so while it was out, did them too.

The pic before was a different bike a couple of hours before when the rider kept riding with a flat E09 Dakar, the stiff sidewall one. The tube was spirally shredded and beyond repair. The tyre wasn't great either, with noticable sidewall damage internally. It was also a major pain to break the bead due to the heat and it welding itself to the rim. Just found these pics FYI, seen a tube like this before?



Biggest fuel range needed on this trip was Arkaroola to Cameron Corner, about 420 kms.

Here's a couple more:

Cool.

420 is a little outside what my 18 litre tank will do on the DR, if I sat on 70kph maybe. Outside what the 16 litre on the BMW does. Again, maybe at 65~70kph the whole way. No reserve, no room for error.

I want to take wifey out there on the F800, but that becomes problematic fuel wise. I'm planning a run on the DR out there soon.

That tube was "well stuffed" hey? Weird way to shred though.

Lucky it was an E09, most others are weaker in the sidewall.
