    I got mad at mine. I kept the old worn out chain and tried to repair the chain slider with various materials. I tried cutting board but it wore quickly. I tried lexan but the JB weld did not stick well enough and it fell off. I was fed up so I bent a piece of steel and attached it to the slider with screws. The chain actually ate into it pretty well and I have replaced the steel piece once. Maybe when I get a job I can afford to replace the sprockets and chain. The chain is not visibly kinked but it still pretty bad and needs replacing.

    Thanks Tom. Yeah it does. There are some scratches, but all of them are in places that I'm going to replace or places I simply don't care.

    It's really tall, and I'm going to have to lower it some. First up is the seat. Turns out I'm really close to Seat Concepts here, so have an appointment to get the seat redone on Wednesday. I'm hoping to get a pic or two at their shop. I'll wait until I get home to do the factory lower, which I think will be enough.

    The bike had 372 miles on it when I picked it up, but will have triple that by the time I get back home. I have a Rotopax, tank bag, and a USB power port arriving this week for the trip back. Lots more to do, but I am looking forward to the ride home.

    Is there any way to display a tach, or do I need to install an add on computer for that?

    People with swingarm damage, what front sprocket are you running? 12 or 13?

    I'm running a 13. Right now a 12. But mostly a 13. Bike has 30,000 kms and I have replaced 3 guards, need another one right now but waiting a bit. I am going to do a full swing arm movement adjustment. I found that the more I weight the bike down the sooner the guard is destroyed. Slack is set fine for normal riding or empty bike but gear up or two up and it will be too tight.

    I had a 13, switched to a 14 and came up with a chain adjust and check tech that has worked well so far.

    I run a 12 or 13.
    Was running the 13 when I got the damage. Stock chain was not that old, but It got kinky when I let the maintenance slip. Kinks will eat that slider faster than anything.

    Unsure if you have read BigDogs mods, but he is not a fan of the smaller front sprockets and has a good theory behind it. He runs a 14 now and changes gearing on the rear. http://www.bigdogadventures.com/WR250R.htm

    I am running the stock 13 front with a 50 rear. Have never used a 12, and wouldn't.

    And that chain adjust and check tech would be...?

    In my case I think the damage was caused by
    1. Chain/sprocket wear, leading to excessive slack.
    2. Several weeks exposure to salt air, 1000's of miles of sand trails, and one spectacularly impassable mud pit that caused the rear wheel to completely lock due to mud packing around the swingarm, chain guide and front sprocket area. Grit and water got past the x-rings and eventually caused several links to kink up.
    3. Riding with the above conditions with a full load of camping gear on extremely rutted/washed out dirt roads, where g-outs and 6" potholes are as common as cardon cacti.

    The loose and kinked chain tends to wrap upward as it leaves the bottom of the front sprocket under acceleration, add in the upward movement of the rear wheel under a g-out which further pulls the chain toward the bottom of the swingarm...

    I'm sure you can get swingarm damage in other situations--say a too tight chain--but it is very clear that the damage in my case was NOT caused by a tight chain. (i.e., much respect to BigDog, but my data simply doesn't jibe) I tightened up the chain slack, lubed the heck out of it, and got home with no more significant damage.

    Utah Fox good luck on your trip. If you can set the shock sag to 4+ inches, should help with the height. Seat Concepts will be a big plus. I am here in Prescott AZ, if you have any issues along the way on your trip just give a shout & I will give any help I can. Good luck & ride safe.

    Hmm... the online reviews for this battery are not very good.

    I didn't look into it at all just passing it along. I bought a new battery about a month ago so it's of no interest to me.

    Thanks! The spoke wrench gauge is a good idea.


    But...

    "The TSB says to do this with the bike on the side stand. I did mine with the rear tire in the air."

    That is a HUGE difference. I suppose there could be a strange coincidence where the relation of the chain/swingarm pivot/sprockets is the same in both cases, but I'm not willing to gamble on that one. Have you checked the slack with the bike on the side stand, in neutral? How does it compare to your slack with the bike on a center stand, rear wheel fully lowered?

    Good catch... Yes, I do this with it on the side stand. By the way, in my case it was the same on the side stand as on the lift in the chock, but on my trips of course it is always on the side stand.

    30bones, I really like the trailer for commuting and for long trips.
