I am also running the stock rear with the 15 front with the stock chain, made a big differance with the 3 mods :thumbsup: have no plans to change the rear.Blownhotrodder said:Im running the stock rear with 15 front and use the stock chain. The chain will show grooves where the sprocket contacts it or the orings start to degrade when its worn.
Obviously, it will need to be changed if you go with a longer swing arm. But it can also need to be changed if the roll pins get severely worn, rusted up, the o-rings fail, and in most cases...when it is stretched beyond what the chain adjustment will allow for. Chain AND sprockets should be replaced at the same time. They get certian wear patters (like a fingerprint), and if you replace the chain without doing the sprockets, it will wear them out much quicker. Visa Versa with new sprockets and an old chain.proarmor700r said:thanks but when does the chain need replaced
