CB550 Camshaft Replacement Question

[smarsh]

Hi,

Looking to try and find a good secondhand camshaft to replace the one in my '75 CB550K.
Just wondering if anyone would be able to tell me what other years of the 500/550 have camshafts that would suit?
The option to drop in a 650 cam sparked my interest, but seems I'm a bit late to find one of those, anyone got suggestions of any aftermarket cams to improve performance?

Hi xb33,

From the specs I can find the 500/550's '71-'78, have the same size lobes. Am I right there?
If the 500 cam is the same size as the one I've got, I'd be interested, let me know a price and PM me some pics if possible.
Also after 1 rocker arm in good condition, if you have one, but I do understand if you'd rather keep them as a set.
