After hearing a few comments on here and doing a little research I was able to ascertain that there are a lot of parts that I can use off the ‘74 TX500 that are plug and play on the 650. I was curious because they looked the same so I looked up the part #’s for a comparison. A visual showed me same plugs, wire colors and similar part #’s but I wanted to know how I needed to read those #’s. The numbers are set up pretty universally in a format.
Part Number in the format XXX-XXXXX-XX-XX
XXX-XXXXX-XX-XX
The first three digits are the Model Code (every model in the Yamaha Product Line has a unique model number) all parts are given a Model Code of the first model they were used on.
XXX-XXXXX-XX-XX
The middle five digits are the Basic Code number and indicates the actual part, i.e. 11631 = piston; 11311 = cylinder, etc.
"W" substituted in the first position of this five-digit group (000-W0000-00-00) indicates a factory assembled kit which differs in content from the original assembly used in production (i.e. 2M0-W0046-00-00 – Rear Break Pad assembly).
XXX-XXXXX-XX-XX
The next two digits are the Design Code and Design Change digits (so 01 means the part has had one design change). This part may or may not appear different, but it will be interchangeable with the original part.
XXX-XXXXX-XX-XX
The last two digits are the Color or Finish Code.
That let me know for example, my right handed set of controls.
TX-371-83963-42-00. XS-447-83963-01-00
That base part # let me know it was the same piece and the only difference is the XS wiring is internal on the handlebars and the TX is only the left side( although the parts diagram shows them both). Im sure this has been discussed here before but I thought that was pretty lucky to have a parts bike fall into my lap.
