Thank You. I guess I'm going to open myself to a lot of laughter here, but a question about Yamaha part numbers:
I have noticed that many of the parts that "look" like they may be interchangeable seem to have the same part number except for the first 3 characters. I learned from Yamaha (a call to Corporate support about 6 months ago) that the first 3 characters identify the bike and the rest are the actual part number. For example, a few of the parts for 99 started with 4WM but many of those parts are superseded by part numbers that have the first 3 of a newer model bike. Does anyone have more info on part number breakdowns.
