All very informative but to the original question: once I have the cam out and on the workbench, how do I tell what I have? I get that the B cam will have an extra lobe for the fuel pump, and I can check for that. But as between a stock (original or regrind) grind and a regrind to B (touring) specs, is there any way I can tell? I need to mic the journals and lobes to determine if it's suitable for a regrind anyhow, but other than those raw metrics, is there a way I can see what the cam is ground to? And where is there a listing of what the grind specs are?

Thanks.
