    I just found on Scott's web site that they sell a sub mount kit for $289-is that what you have? Although yours looks a little different than mine; I'm not sure if I pick up the sub mount kit it will actually work with mine.Your risers look like mine -from Scott but are they taller than mine to achieve that proper height I'm looking for?

    I've got the sub mount and it measures around 3.25" from the top surface of the top triple tree to the split of the bar clamps. From the photo you posted and the one 10Cup posted, the sub mount looks quite a bit taller.

    Off road steering dampers don't have anything to do with the motor or steering geometry. They are about terrain and speed.

    I have also wondered about them on the WRR too. My thought would be if you were doing desert racing type speeds, but not sure about other necessity situations. I can not comment on if they are needed for rocky terrain, as I have no experience there.

    Around here, we hit long stretches of sand, not usually more than 40-50 MPH. In those cases, our typical method is lean back, hard on gas, steer with pegs/weighting, and light grip on bars, letting front end dance where it wants to. As a street rider for 20 years, being comfortable with that front end dancing thing took me a while to get used to.

    I have used dampers on sport track bikes, but they are need( IMHO) there more for cases like coming out of a highspeed corner at 80 MPH plus, and front end getting light while trying to get on the gas.....perfect recipe for a tank slapper.

    Correct Pantah, The purpose of the steering dampener is to slow down the speed at which your handlebars are jerked to the side when you hit an unanticipated rut,rock, or uneven surface so that you can more easily get your steering under control. It works at all speeds independent of power.

    I tried searching this vast thread for the following info but came up with nothing.

    Wolfman seems to be what the majority of wr250r owners have for tank bags but I was just wondering if anyone is using another brand that works well. I am trying to pick up a few things for my new to me 09.
    Thanks

    Check out the Giant Loop Fandango tank bag. I've tried a couple different tank bags and I like that one the best so far for that bike.

    I got a Metzeller six days extreme front and Mitas extreme rear.
    Rode in the woods both saturday and sunday. Boy i cant remember having this much fun lately

    This engine is definately built for riding high RPMs which adds to the fun factor.

    But the bad news is I broke clutch lever and one of fork seals is leaking oil right now. I have to change the levers without breaking the bank. Any suggestions?

    Stock? The levers are like $10 each IIRC.

    I went with drc shorty levers. They're only about half an inch shorter than stock, but it should be enough to keep them from bending or breaking in drops. Plus they're $7 each or something.

    Tore down the engine yesterday on my R after it failed a compression test. Showed about 30psi on the guage.
    This last summer my bike died on the highway suddenly. No power, and a puff of smoke suddenly came out the back end. Come to find out, the oil had suddenly disappeared. (I checked it less than 10 miles before it died.) I bought the bike used, and managed to put only 2 tanks of gas in it before this happened. :cry

    Months later, I finally have time, and a buddy available to help who has all the tools.. (Amazing how hard it is to get together when he travels for work, and I have a newborn in the house. :D )We tore it down, and found out the compression ring is broken. Fortunately, all the parts stayed in the groove until we coaxed the piston out of the cylinder (packing the bottom end before we did this.) All bits recovered! :clap

    While I had it apart, I tested the valves, and found that 3 of the 4 are definitely leaking... the 4th looked moist, so it probably is too. :huh
    Now to find a machine shop.. Kinda sad for a bike with about 8k on it.

    I sounds like it may have had a pretty severe over heating event while in the hands of the PO.

    Anal fact for the day:

    A DAMPER damps excessive movement, such as handlebar jerk or a bump.

    A DAMPENER makes things more damp or wet.

    So a steering damper will help you keep your front wheel in your intended direction.

    A steering dampener will keep your steering assembly damp and wet.

    :D

    I usually take my dampener off this time of year. Why wear the thing out when everything is damp already?
    Usually have to let stuff dry off a little before it can be properly damp anyway. <G>
