Wasn't going fast at all (or my 61 yr old self would have broke something). Seems like front tire wanted to do one thing then rear another and I'm wadded up going OOOOOOFFF!. Any hints other than sell the bike?
Why did you bump your pressures up to 30? I think his comment was a tongue in cheek comment meaning even a good off road tire handles like crap with too much air in it.

20 psi is even a little high for me when I'm doing serious off road. I tend to ride closer to 17-18psi or sometimes less, but 20 is pretty safe. 30 is way too much off road and as you found makes things way worse. I even think the max pressure on some knobbies is under 30psi, so pay attention to that too.

If you're in real sand, the lowest pressure you can possibly run is best.

I have a Clarke tank, does anyone know which aftermarket caps fit this tank. I'm looking at some RHK ones like this http://www.jtr.com.au/pdfs/rhk/rhk_alloy_tank_caps.pdf
I have the original plastic one but it is cracking so thinking it would be better to replace with something Ally.

Thanks.

if you need 6-8K in a single tour run then yes they are priceless. if you are back home to change with in 3-4K and you don't mind the change then shinko 242, IRCs etc. make more sense.

one sleeper and little talked about $90 high-mileage tire is this one:

Eakins, I "accidentally" got a pair of TW22s (they were the only game in town in some small town in northern CA) and found they weren't bad, but they only lasted a tad over 6000 miles, compared to over 9000 for the Metzeler Tourances I usually run. The 'Stones were a bit better in the dirt.

CSS damper?

I saw there is a damper that goes between the counter shaft sprocket and the retainer plate. I know it is not necessary, but should I get one?

Sure, if you are bothered by chain noise. The only function of the damper is to shush the noise of the chain running around the sprocket.

Ok, don't care about chain noise so I do not need. Thanks.

Why 30? Because I'm learning here and it seemed to me that 18 wasn't enough for a fat guy and I didn't want to pinch a tube. I run 30 or so in my F800GS tires so I figured I'd try that on the DR since I can drop it all day and not spend the money fixing it I'd spend on dropping the F800 once, not to mention the DR is a hell of a lot easier to pick up. Just want to ride and not fall over so much.

Exactly! Off road ... and especially in deep sand ... I run 15 psi. Up to 18 psi in faster, rocky conditions. No problems with D606 rear tire. No rim lock, but if you run LOW pressures, its a good idea to install one.

Hey Richguzzi thanks for the seconding it's nice to know we all share a common goal.
Shady Rascal and Adv Grifter that was exactily the kind of info I was looking for. I think I probably don't really like deep sand (except it's soft to fall in) and "faster rocky conditions" UH, I vote NO. Thanks again.
Did yall see that DR guy Joe's helmet Go-Pro video over the cliff???

Yeah, it's a balance between the lowest pressure you can go, and the weight the bike will see.

A lighter guy will be able to run tires at lower pressures if everything else was the same (same obstacle, same speed, etc.), but you had part of the equation right for being a heavier rider. If other guys are running 18 with your tire, then you may run 20 or 21. Something like that.

It's always a gamble based on all the information and experience you have. My firends and I went through the same decisions when riding mountain bike tires in varying terrain back in the day. You gamble, and you win, or lose against the pinch-flats / snake-bites (not sure if motorcycle tubes can get snake bites, but mt. bikes sure did from running them to low).
