MAINTENANCE AND ADJUSTMENT 91 between the chain and the swingarm) to 62 ∼ 68 mm (2.4 ∼ 2.7 in.). When the chain has reached its wear limit (i.e., when it has stretched by 1.7% of its original length), it is no longer safe for use and should be replaced. Since it is impractical to measure the entire length of the chain, determine the degree of wear by measuring a 20-link section of the chain. Tighten the chain either by using the chain adjusters or by hanging a 10 kg (22 lb) weight on the chain. Measure the 20-link length on a straight part of the chain from the center of the 1st pin to the center of the 21st pin. If the length exceeds the service limit, the chain should be replaced. Since overworn sprockets will cause a new chain to wear faster, inspect both the engine and rear sprockets whenever the chain is replaced, and replace them if necessary.

Service Limit 323 mm (12.7 in.) ○The drive system was designed for use with a DAIDO DID 520DMA4 114-links chain. For maximum stretch resistance and safety, a genuine part must be used for replacement. ○To minimize any chance of the master link coming apart, the master link clip must be installed with the closed end of the "U" pointing in the direction of chain rotation.
