I'm getting this awesome knock when I first take off from a stop. Sometimes it happens if I'm braking and then accelerate (like red light turned green). It doesn't sound like the engine, but I can't hear much. Another rider said it sounded like it was coming from the front brakes. Would seating low pads cause the noise? Sorry for the craptastic pics, but this was all I could reach:

Walk the bike forwards and backwards in the garage, engine off, and see if you hear the sound.

Could it be chain slack ?

Brakes look fine to me. I had a similar issue many moons ago it seems and remember it going away once I tightened the chain up. How many miles on the chain BTW?

Went up and down street. It's only when I'm really slow and generate speed. With no helmet, it sounds like it's behind me. Roommate is rather high atm, but says it sounds midbike/front sprocket area. Checked chain - was not loose.

10k on the chain

Do you only get it when the clutch is engaged?

is the chain binding? when it is time to change it and it is binding like mad, sometimes itll slap the chain guide going in to where the front sprocket is.

could it be a head bearing? make sure your brake calibers are torqued to spec.

Bring it to highway cleanup and I'll take a look.
