Yes they come as one

Your hotcam should have a bearing on it already:confused:

I'm pretty sure the bearings are pressed on before the gear... it would be cheaper to and better to buy a new cam but I am little confused in that you say you are installing a new cam anyways:confused:

I would be concerned about any pieces of the broken bearing falling into the head passages or down into the timing chain passage and into the crankcase cover:eek:

Do you have pics?

What year is the bike?

Sorry to hear about this, I would make sure that all of the bearing pieces are present and accounted for. How was it running before you took the valve cover off and found the bearing issue?
