    :clap

    I think all DR250/350/650 can swap wheels. Some are a bit different (cush drive VS solid... discussed a few pages back, and DR650 has 17" while the 250/350 are 18"), but can be swapped back and forth anyway.

    To match most closely with your bike, any rear wheel from street model DR250 90-95 or DR350 90-96 should be 18" with cush drive.

    I am making a list of things i need for the Roaming Rally in canada. I have a spare clutch cable, I plane on having a spare throttle cable as well. And spare wheel bearings(front and back), also spare pads.

    Anything else come to mind?

    Never done anything like that, but I would think, clutch lever, shift lever, fuses, headlight bulb ?, tube...

    I don't know as if wheel bearings or brake pads would be on a list of spares I would carry. If they are suspect, change them prior to the event.

    As for the throttle and clutch cable, route them alongside the existing cables so if you need to use them it's easy to get them changed out.

    The 650 has a different brake rotor on both ends.

    My neighbor's DR350 had some cracked links on the chain two weeks ago after some desert riding. We figured it was just due to age or perhaps a faulty chain. He picked up a new chain, RK non O-ring and installed it and we figured all was well. Less than 200 miles, it's cracking again.

    All cracks are on the inside of the link, same as the last chain. He recently had the rear swingarm off to clean and lube it all up, and he had the sprocket off also. Is the front sprocket installed correctly?

    I think the collar on the sprocket should be facing outward instead of inward like he has it. Perhaps this is causing the chain to hit the case saver and cracking the links?

    Does it have 520 sprockets on both ends or badly worn ? Looks like something is trying to pull the chain apart. :scratch

    The sprockets and first chain were not that old. Maybe 1500 miles at the most on them. I've never seen a chain do this before.

    If the chain line is right, and nothing is hitting the chain, it's got to have something wrong with the sprockets or chain. Not likely to get 2 chains crack the same way. You might switch out chains and sprockets with your bike, or pull them off and compare, just as a test.

    I guess I should double check the swingarm install, too.

    Front sprocket mounted correctly in your opinion? The shoulder on the sprocket is on the inside. Seems to me it should be on the outside, next to the clip?

    check rear wheel alignment too. i'd measure from swingarm pivot to axle, should be close to equal side to side

    I agree, it makes sense that the shoulder should be on the outside. But, to the best of my knowledge, that is not correct. Instead, the shoulder should be on the inside.

    I am not sure what would be causing that pattern of failure. The rubber swing arm protector looks worn, but I can't see that it would cause this.

    I know it does, and so does the workshop manual. I have never seen an original Suzuki countersprocket, but I suspect they had collars on both sides. I know all of the aftermarket ones I purchase today do not. I do know that when I mounted the collar to the outside, that I got a lot of side wear on the teeth. Now that I mount the collar to the inside, I do not. For whatever that is worth...

    It needs to be mounted so that it will not rub on the case saver AND be aligned as possible with the rear sprocket. Pragmatism rules! :>

    Also, I recall reading somewhere that the collar goes to the inside, but I can't find that reference. Sorry.
