Does anyone know how to tell BOB cams from BOA cams I.e part number/engraving or something?. I had just bought a set and I want to make sure they are BOB ones before I waste my time putting them in

 

Only different shape loabs, not sure if there are any markings though? Have they got any parts no's

Have you got the bob washers?

 

Easy way to tell with one of them is it will have phase sensor lobes on.

 

I had alook at the cams yesterday and the numbers engraved into them were different to the ounces I am currently running but I didn't write them down so I'll do that today and post them up

How do you identify the phase sensor lobes?

Yes I have they bob timing washers and value springs

Cheers everyone for your help
