i followed a link in another thread and found these. anyone care to chime in on the comments below? in my case, i'm wondering about my 550's camchain, as i'm in the low 30K mile range. author seems to be referring to UK bikes... -jon

Classic looking but lacks any blood and guts, although the power and chassis work well together. Simple for a four, engine tough to 30,000 miles when camchain can snap. 40k means rebore but can run for 60 to 65000 miles before complete rebuild’s needed – if oil changes done every 1000 miles. Check for slick gearbox, lack of head gasket leaks and bodges to camchain tensioner or electrics.

Update on the CB500/4, with more punch and better handling. Most chronic problem’s cutting out in the wet – fixed with new coils, HT leads, caps and plugs, plus a few tubes of sealant! Runs happily to 35k when either camchain, pistons or tensioner give problems but some made it to 50k. Quick rot exhaust and caliper, plus base gasket leaks. Still a few nice ones running around but the majority are drifting towards rat status.
