I found an old thread from 2003, and it said that the "Bumps" were the wheels that were questionable. The S/N on my engine is 1K158, and the printed manual is from 2002. So, I guess I can assume it's a later engine. And, hopefully, it's when they decided to start x-ray'ing.
Last question.... when did they go out of biz? (year?)
