I was cleaning my chain w/ a 3sided brush and it got caught in the rear sprocket and broke the bruch and de-railed the chain. I put it back on adjusted via leveling the swingarm to get the max tightness then gave the chain 1/4 inch slack. I took the bike out for a test run, heard a clank/rub, clank/rub. I looked down and found the master link rubbing on the left mount bolt for the sub-frame. so I took off the rear wheel and inspected the rear sprocket for and bends-OK, checked the cush drive-OK, After talking w/a few guys at work the theory is my chain is bent a little. Should I 1-Replace=$$$ 2-flip it over so it does not hit on the outside. 3-take the chain off and put on a level surface and dead-blow the chain back into shape? Has this happened to anyone else? Not the stupid part but the repair part w/o any problems? TIA Kurt Thomas

I'll let someone else address the bent chain thing; I've never heard of it. I'm writing to say that you were lucky. You could have trashed the countershaft instead. If I understand you correctly you adjusted the chain way, way too tight. I push the chain up against the bottom of the swing arme so it's about 1/16 " inch short of touching if you push firmly but not with all the power you have. Bogdan

I disconnected one of the links so the swingarm traveled freely(shock was out of the loop) made the sprockets level/inline w/each other. then gave 1/4 slack then let the rear wheel down and put the link back together. I belive in this case(i could be wrong) I set the slack when the swingarm is mid point between max bottom and max topped out. (i think i said this right)

that sounds a lot better as your first description had us all reaching for the keyboards. I just lean over the bike from the right side, grab the swingarm and pull down (since my heads now dow, I guess I'm really pulling up, aren't I??) until the swingarm is level, or really when the chain is at it's tightest arc. That's where I measure the free play. What you'll find is what was described earlier, and that's that the chain will "almost" touch the swingarm from the bottom with no weight on the bike. Just my Monday $.03 worth. Ron in MN

right so i do have the correct tension set, but i have side to side play when i ride and it hits the left subframe bolt. that why i think my chain is bent. the question is to replace or repair this think now. Kurt Thomas

From what you've told us, I doubt very much whether your chain is bent. Perhaps your rear wheel is cocked a little to the left. Check your wheel alignment. FWIW, I tension my chain with the bike at rest on the sidestand. Then i pull the bottom run up against the swingarm. It should just touch the swingarm, with the top run now pulled tight. Essentially the same method as Ron Crandell's.

You were holding a 3 sided brush on the chain with the motor running and in gear ? BEEEeeeeeeJesus still got all your fingers ? I would buy a chain myself, since if its bent and you run it like that no doubt it will wear the sprokets and maybe depending on how much it is bent might do other harm to the countershaft bearings or seal. Some have reported good luck with cheap chains and lots of WD40, or other cleaning/lube stuff thats like it. Dooden Last count still has all fingers and thumbs, one finger is not straight as it should be, but thats what ya get when you set them yourself I suspose. Arrrrrgh....

You said it before I did. I can point the gent to a dude who was wiping the excess lube off the chain of his GTS with a rag, engine running and in gear. He's now missing the end parts of three fingers. Personally, I ain't no saftey-crat. Done some, uh stupid, things in my day, but I do draw a line. Guy At 11:25 PM 4/14/03 -0000, dooden wrote:

I think the chain reaches the bottom of the swingarm real easily (suspension compressed). Its been like this for the past 2k seemingly w/out negative results.

I'd be hard pressed to give 'em $200. Not worth it. If my memory serves, you are going to need, complete top end, piston, rings and possbibly bore cleaned up. More than likely a crankshaft seal. Carb cleaning, All new cables. wheel bearing, tires and tubes. chain and sprockets. Just my humble opinion, a 100% pure dirt bike or race bike should be two stroke. A woods, trail and some street should be a four stroke. Watch e-bay for a KLR250, DR350, XT350, TTR-225, NX250. These are a few versions of a much better deal. Understand you a looking at the worst possible time. Everyone else is looking this time of year as well. Keep checking e-bay for a small bike. Don't give $400 for anything you can't ride home.
