Why 30?

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.
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).

I did put in a rimlock. I run 15psi rear and sometimes as low as 13 front. (full knobbies)

I wish I would have had my DR650 on this ride. I was running 22/25 PSI in the TKCs.



This was the easier part, it got steep and rocky and I made it through on the Tiger without too much difficulty, but it would have actually been fun on the DR. This was totally my fault, I had been rolling along OK through a few sandy sections, then this one I looked down and yep that's where I went. Don't know why I struggle so much keeping my vision up when riding rough sections, it's so fricken easy when I keep my eyes up and looking to the end of the section.

PS The Tiger made it through a couple spills with no damage but it sure ain't a dirt bike, especially in my hands.

You done good! I've never ridden a XC Tiger off road ... but on my V- Strom I ended up like you ... on my ass. Tires and pressures only go so far on a bike like the Tiger XC or VStrom. Weight is not your friend.

The DR, with good knobbies and low pressures, does OK in deep sand ... but you still need good rider technique to make it through. I did similar stuff in Baja on my DR ... and once I got "up to speed" (mostly in my head), I did OK. I kept speeds mild and the 'ol DR just motor'd through. What is hard in deep sand is if you come to deep wash outs or tight S curves ... getting through those in foot deep sand is not easy ... and I fell a couple times doing it on the DR. A heavy luggage load makes it even more challenging.

Riding a gear lower than you usually would and keeping the revs high and the wheel spinning was the ticket in the sand of southern NJ. (sugar sand)

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?
Yup, even a good knobby needs to be at an appropriate pressure to do it's best. I often drop to 15-20psi in the sand. I don't have rimlocks. This IS going to vary with the weight of the bike and it's payload, the stiffness of the tires, whether or not a rimlock is used, and on the likelihood of encountering hard objects in the sand like rocks and roots. Experiment until you find what works best for you. Even at 22psi (street pressure), I notice a big difference between the stock front Trailwing and the AMS Sand Snake knobby in the soft stuff.

As far as technique, I'm no expert, but this is what seems to work for me...I try to get my weight back, stand up, stay loose, and stay on the gas until I'm ready to turn. When I want to turn, I come down to the seat as far forward as I can get, (I might downshift, if needed.) kick my inside leg as far forward as I can while keeping my toes pointed up and a slight bend still in my knee, and stay on the gas. A lot of the time, I'll give it even more gas through the apex to get the back end around and to get the bike back up to planing speed. If there's a berm, I use it, but I'm not usually throwing a shower of sand from the top. I still fall , but I don't dread riding pillowy sand for miles at a time on the DR.

Off idle stumble

I recently put the ProCycle jet kit with air box mod and twin air filter in the DR. I'm happy with everything, but now I have this issue where from idle if I give it any throttle, it dies. If I blip the throttle I can move without killing it. Is this idle mixture screw adjustment, or something else?

Maybe I'm better of pony'ing up a bit more cash for a newer DR.
Falcon86,

My 99, purchased in '09 had the solid gear and was ok after 24k miles. I could tell the stator case had not been removed; the fasteners had not been touched. I negotiated a $200 price reduction and changed the gear within a couple of weeks: http://advrider.com/forums/showthrea...7#post13437857 It is an easy part to change - took all of 15 minutes...

Regards,
Harry
