That sounds like the right side TB shaft and bushing are shot. I did mine on my 02 GSA with 90K on it, settled that knocking right down. Then 2K later I did the left side both were pretty well shot. I order the kit from Dan Cata, worked perfectly. If you want to be sure it's the TB shaft, put your finger against the inside of the TB and press on the shaft cover, see if the knocking stops or changes pitch, if so, that's your problem.

Good Luck.
