Keep the 124-link A chain and 82-link B chain separate in the work order. The smaller B tensioner has its own matching spring, while the larger tensioner is a different component. Part appearance or the CB750 name alone does not establish the right choice.
Cam timing and tensioner work affect engine operation. Assess the guides, springs and tensioners during the repair, then follow the exact Honda service procedure. Do not assume a separately listed rivet link is suitable for a chain without confirming its chain specification.
No. The featured A chain is 412H × 124 links and B is 412H × 82 links. Identify the chain position before ordering rather than choosing by the shorter or longer appearance alone.
The B product is identified as the smaller cam-chain tensioner. Match its reference and location to the engine diagram; the larger main tensioner and its spring are separate choices.
The featured chain products describe the individual chains. Tensioners, guides and springs are separate products. Inspect those components and build the repair order around their measured condition.
