I had the same problem when I originally installed Jim's Spacers on my 03 TA. It was definitely caused by the cables being too tight on a full right turn.
I was able to fix it rather simply. On the left side of the frame neck there is a large lump of wiring harness. My cables originally ran below that lump. I positioned them above the lump and it gave them enough slack to eliminate the problem. You might try that first...
