    I'm hoping to improve my stability in sand a bit. I'm wondering if doing the stock lowering on the rear, but leaving the front alone will help without messing up my handling too much. Has anyone tried this? Thoughts?

    If it matters, I'm about 155 pounds (without gear) and all I've done to the suspension is set the sag and increase rebound damping.

    It is more about technique. The wrr has a relatively slack fork angle which is what lowering the rear does.

    Lean back. Use throttle, and realise there is no stability in sand. Just get comfortable with a constant front end hunt.

    Alright, I've made a down payment on an 08 WR250R with only 650 miles on it. Will pay it off this week and then wait for delivery from PA. Soon, very soon. :clap

    I get 70 mpg (vs 63mpg w/ 10%) loaded down and riding 'easy' on dirt using pure/clear gas. That is 140 miles vs 126 miles on the tank or 189 vs 210 miles carrying a gallon. Up in the remotes it does make a difference between getting there and not getting there.

    I've got the stock trailwing on the back still, swapping it for a 120 t63 today though.

    Hmmm... does the cover come out of the right or the left hand side of the bike? Anybody have a video or pictures of the top end? Kind of feeling my way through it.

    I'm pretty sure I pulled the cover out on the non-radiator side, but I can't remember. Took a lot of wiggling thats for sure. Only had to do it once a long while ago ya know? :lol3

    I'm sitting at just a hair under 43,000 miles and haven't seen further than under the valve cover to do a clearance check. Intake valves were fine, exhaust were barely out of spec, at ~25,000.

    I am a bit heavier.. well a lot heavier than you (250 lbs) and the single best thing I did to improve how the bike handles in sand was to install a steering stabilizer (Scotts with a SUBmount in my case). Granted I am not a very aggressive rider but the Scotts unit made the bike so much more manageable on the south GA sand roads.

    I was afraid I'd get that answer, $500 sure is a lot. It is probably the answer I'm looking for though...

    After thinking about this bike for over a year, I finally took delivery of a new 2012 WR250R. It is a bit cold and snowy in New York, but the short rides I have done on the bike left me with a giant grin on my face. My hopes are to start modifying the bike for a trip down to South America in a year of so. In the mean time I plan on exploring the dirt roads on the East Cost, just moved here from the San Francisco Bay Area.

    One question I had was regarding tank options. I am trying to decide between the Safari and IMS 4.7 tanks. I like the idea of the larger 4.7 tank, it would make it less likely to have to carry spare full on the rear rack, but I have not seen many reviews on the IMS 4.7 in the thread. A lot of people have the Safari with good feedback, but few IMS 4.7 tanks. Any issues to be aware of with the IMS 4.7 tank, does it fit with the Flatland radiator guard? Any feedback advice of feedback to help me choose between the IMS and Safari is greatly appreciated.

    Here is a pick of the new ride. So far I have added Cycra probend hand guards, sandman case saver, and a Pro Moto rear rack.

    You don't need a stabilizer.

    When you ride in the sand:

    1. Stand up. It lowers the center of gravity and stabilizes the bike.
    2. Stay on the gas. It shifts the weight to the rear and allows the front to "float" across the sand.
    3. Steer with the pegs. In deep sand, shifting weight to the right peg with help you steer to the right and vice versa.

    Comfort comes with experience. True knobbies don't hurt either.

    ...I have a Scott's on my WR, glad I do and I'll tell you why.
    Being a senior rider I don't have the strength nor the reaction I did 20 years ago. A stabilizer makes the bike more forgiving and the mistakes more forgiving and less jolting to the old bones.
    Having the suspension done is the biggest aid though.
    Considering $500...spend it on the suspenders, then think about stabilizers later...

    There's alot to be said about sand riding technique. It's easier to say than to do.
    I grew up in the desert riding sand whoops, and never did get it right.
    It's even harder now.
    The stabilizer is my friend. ;)
