The FIR Timing Chain Camchain Breaker/Rivet Tool
When working on motorcycle camchains one thing that quickly becomes evident is that there is usually a need to break and rejoin the camchain. This will arise either because the new chain is too long or because a continuous new chain just cant be fitted short of a bottom end rebuild. Many new camchains are actually supplied with a joining link to overcome these problems. However, this is a rivet link. It is most certainly not the reusable type of chain master or clip link found say on drive chains, and although such links are available in size 25, they are for use in external drive chains in small monkey-bikes and the like. All sources agree that this type of link should never be used in a camchain and the rivet type is essential. However, although they can break smaller chains, most motorcycle chain tools cannot rivet anything smaller than a 35. My moped uses a 25H chain but thesezare expensive precut to the correct length (70 link)and so I bought an 80 link Chain for shorte...
