My Scrambler Desert Sled has 9,200 miles on it. A few days ago I had someone adjust the chain, as it had excessive slack. Once re-adjusted to spec, all was good as it always is with this. I get to my house 6 miles away, and notice the chain had become really taut, evidently rear axle nut was not tightened to spec, and wheel slid backwards causing tension on chain. I took it back in a flat bed, not wanting to risk it. Process repeated, this time correctly. Have put on the bike 60-70 miles after that, no problems. I've also inspected the whole chain, and cannot detect any damage, but hey, what do I know! Measuring the links to see if chain is in spec seems the best way to rule out chain needs to be replaced. Trouble is I cannot find in the manual the length I need to look for in order to make this determination. Any leads on this will be appreciated,
Time to invest in tools & do it yourself. After all you could of suffered a broken limb or worse. Had the same happen to me'
Chains are tough old things, they can take a bit of abuse. You’ll be fine, just do it yourself next time.
I’ve always replaced mine if I had any concerns. Just not worth the aggro they bring when the links decide to divorce each other
Chains wear on the rollers, micron by micron X number of links. Sprockets the same. In 45 years as an Engineer I have never seen a chain with side plate stretch on a road going motorcycle. I have tested chains on rigs for tensile strength new out of the box and after extended use. Seen rollers split due to incorrect heat treatment and external roller pitting A chain is accepted as knackered when the chain can be pulled away from the sprocket at the centre rear point easily when correctly adjusted. Roller wear and sprocket wear allows that,not stretch. When I use the term rollers that includes pins. So I very much doubt you have suffered any harm to the chain if it did not leave the sprocket. If a chain parts it is almost without exception the link incorrectly fitted or rarely now a departed split link. Never buy knock off cheapo chains. Used to be Renold, now I would go for DID. Quality control and selective product testing both non destructive and sacrificial is built into the price of the chain and sprockets. Simple rule. Wheel alignment, correct adjustment, decent lube. Lube has been done to death on here. Never bought a spray can of overpriced packaged miracle goo. Nice drizzle Ep80/90 regular and on a warmed up chain. Get yourself a torque wrench with calibration and a decent quality socket. If this is the original chain price up replacement costs. Always fit a new chain on new sprockets. Enjoy and remember you have a front wheel to put on the ground occasionally.
Shit this reminds me to unwind my torque rench at home after adjusting my own chain. Never dropped the Nm' down from 180. Derp..
