Just as the title says. I have a problem where the bike will make a clunking sound similar to that of a bad cv shaft on a FWD car. It happens when Im moving from a stopped position. Acceleration doesnt matter. Being that I am a mechanic I ruled out engine and went to tranny. Lets do this like House, a differential. Ideas and explanation please.

Note: I am just guessing tranny I have no experience in bike maintainance except oil change.
Also, I rule out engine cause 1) Sound is to the front and low. 2)
Engine sounds fine

Bahahaha, lupis.:killingme

How is your chain? Sprockets? Brakes? Is in consistant while you are moving, or just when you start off? Does it sound internal? Are you allergic to shellfish? Does it change with RPM? Can you replicate it while you are standing still, or does it only do it while moving?

Chain tension off spec, methinks.

^ Agreed. Check chain slack.

Cush drive in the rear hub needing attention ?.

Chain. Clean, lube it & make sure it's adjusted properly. If clunking doesn't go away or starts again in a couple of hundred miles, chances are real good that you need a new one.

Seriously - people ask for help but not very often do they post the follow up of "Yes, idea number 3 was the problem." It's like loaning someone money and they don't even say thank you.
