    Hey Galen, we were just up in the Churchville area a couple weekends ago. We don't like driving on the interstate so usually take backroads, and went to the Dayton Farmer's Market for lunch and shopping. On the way home we decided to see what the Natural Chimneys are all about since I'm a geologist and enjoy looking at rox:

    After we left there we decided to go exploring and got totally ferking lost in the mountains west of C-ville, found some excellent trout streams, and finally popped back out on Highway 250 about ten miles west of Churchville and made it to the gas station with about half a gallon to spare in our Toyota Corolla. It was fun exploring those back roads but next time I want to be on a bike - the little car did fine, but it's brand new so my wife was grimacing about all the mud and scraping noises :lol3.

    I bought a 2010 WR250R ten days ago and because of work and weather have gotten to ride it a whopping 20 miles since purchasing it. Here are a few shots of that short but excellent first ride:

    It took some effort but I found some mud and snow:

    Then, the weather happened again. This was today (Monday), about ten inches on the ground but melting fast.

    Same location as the first bike picture above but a tad more snow...

    Turkeys were out and foraging, we saw a large flock but couldn't get a picture. They're big!

    [​IMG]

    I'm ready for some drier weather so I can get the bike out, put the lowering link on (I'm 6" shorter than the PO), and go for a long ride! I'm loving it so far...

    I'm right in the middle of this, and can't figure out one thing. I've got everything setup, I've run out the adjuster nut 25 +2 clicks, and I've loosened the lock nut below that up to a point 2-3 threads below the adjuster.

    [​IMG]

    What I can't figure out is how to get the lower shock mount block up to the lock nut. If you just grab the block and turn it, the piston shaft and spring etc just turn with it. There is a 'nut' (red arrow below) right up against the plate at the bottom of the spring, if I put a wrench on that and turn the lower block it turns, but its very hard and I want to make sure I'm doing the right thing here.

    SO - do I hold tight at the red arrow here, and turn shock block (yellow) clockwise to shorten the the assembly?

    Hope this makes sense.

    I see lock tite........... that's most likely your problem. Mine just turned up with no issues. Clean the blue stuff off, put a little wd-40 on it and see if it will turn without turning the shaft, and yes you can back it all up holding the nut on the bottom of the shock.

    I also found out you can bottom the threads out and make the bike as low as it will go, and the adjuster will still adjust just fine. I only have mine out 3 clicks for max rebound damping.......... the best setting on a stock shock.

    But I am on the right track? I've done the WD-40, but didn't know how to get that Loctite off, and suggestions there?

    Thanks Bob.

    You're doing fine. Just run that jam nut up until it bottoms out (assuming you want max lowering) then screw the yoke up to meet it. Bolt it all back up and nun the jam nut down against the yoke. Hold it with the nut just under the spring if the lock tite is a problem.

    Funny, these things never go super smoothly for me, and since I'm somewhat of a new mechanic I always question whether or not I'm doing it right. Thanks for your help.

    Hopefully I didn't steer you wrong, but I know when I had mine apart this winter I ran that jam nut all the way to the end of the threads, and it all worked just fine.

    Hand Guards Update --> The guy at highway emailed me and said I'd have to get a new handlebar in order to use their hand guards. Also, there's some other problem he mentioned. Too much hassle so I'm going with the Cycra (sp?)

    Skid Plate update --> looking for a good dealer. Someone here PM'ed me and offered me their used one which may be a good option. Are there any bad skid plates - ones that are too flimsy or ones that don't fit well?

    Just went through this 2 days ago. There was Loctite on the threads of the shaft, and grit in the threads at the bottom of the block. I was not able to get it closer than about 1/2in to the rebound adjuster. I threaded the block all the way off the shaft. Then I cleaned off the threads on the shaft and the threads inside the block with a wire brush. I threaded it back onto the shaft, and then I was able to thread it all the way up to the rebound adjuster.

    Good luck!

    Here is the model I used. 14 gallon(53L) rubbermaid tub.

    Here's an 18 gallon for comparison. Either one will work. They share the same top and stack together.

    Get yourself a new fuel pump on the way now. This one is not long for this world.

    Been there, done that.

    Don't bother trying to "save" or "improve" the situation.
    This is THE symptom of having an effected and faulty fuel pump that will fail because it was not assembled with adequate clearances for the internal parts to move without seizing-up the pump when it's hot.

    If this happens in the heat of summer, you'll be waiting 45 minutes for things to cool enough to restart.
    Ask me how I know (on 2 occasions before I caught on).

    The solution is replacing the pump.

    Brilliant - gives me something to aim for, thanks.

    ... and I can make a fork seal cleaning tool with some of the leftovers, too.

    This raises a question from me. I bought my WR used, and it may have been lowered by the original owner. What's the "stock" setting for the shock clevis? Is there a measurement from the top of the block to the rebound adjuster?

    Just adjust it for your height and sag. It's personal.

    Will do, but I'd like to know what the adjustment range is.

    Resistance is futile so I joined the Dual Sport Movement!

    Last fall I moved to northern Arkansas and decided that after years of street riding I was going to get back into dual sport riding. I love riding gravel and dirt roads and there are a gazillion here. I narrowed my choice of steed down to the the WR250R. But the problem was when went up for sale, it went fast and none were close to me. I had resigned myself to a long duration search before I found one.

    Then Fate stepped in. Last Saturday my wife was out driving around in the Miata and called and said "honey, you should ride this road in Missouri on the motorcycle because its so twisty". I left the house 20 minutes later and there, 25 miles from my house, sitting alongside the road with a "For Sale" sign on it was this, exactly what I was looking for and in the right price range. Turned around and stopped and took a test ride. And I had my checkbook so I could leave a deposit. After doing a price/features check with some of my dual sport friend in Houston it was sold to me.

    2008 Yamaha WR250R, nicely farkled now lives in my garage.
    Now if the temp would just get above 40 so I could ride it and get used to the tiny and narrow machine that it is!

    It is my understanding that the total height range adjustment available is .9 inches, and they come adjusted all the way up (tall) from the factory.

    The previous owner of my bike also had the rear spring compressed (preload adjusted) so stiff that my 125lb wife was getting almost no sag either. Measure your spring height and adjust the preload too. The proper amount of sag makes a big difference. You can read my comments on this thread over the last few days. In summary, I lowered the bike with the clevis block and a yamalink. It was still too tall for my wife. I adjusted the preload for @ 3in of sag, and that made a critical difference. I still plan to put softer springs in the forks (not getting proper sag in front), but now she is at least able to get her toes on the ground and give it a go.

    Anyone know if the stock dash/computer/odo has to be installed? I've got a replacement on the way, and if I can I'd just like to get rid of the stock one.
