[QUOTE="SRAD97750, post: 224361, member: 425"] O-ring chains are for road bikes to keep them quiet. Rollers in the chain system are there to maintain the chain tension when the swingarm has moved out to an extreme and the arc leaves the chain momentarily loose. If your bike didn't come with one, it isn't necessary due to the swingarm geometry inherent in that model. I have found in custom fabrication, the #1 most important component is the chain guide that aligns the chain with the rear sprocket. If this unit is aligned correctly and has good sliders installed, the chain can be completely loose and never have an issue. I am convinced your chain and sprockets are toast, or perhaps a new chain was put on old sprockets. They should be changed as a set. The rollers wear and the teeth are matched to the wear, otherwise the chain/sprocket wears really fast. These are the only two reasons a chain would need actual additional adjustment after a single ride. I ride streetbikes that use the same exact chain as my dirtbike, with 4-5 times the power. No dirtbike is stretching chains. -BIG DAN:thumb: [/QUOTE]
