Yeah, good on ya, Bob, for coming up with a very reasonably priced SRX, most of the ones I have seen advertised have asking prices in the $3500 range. Mike Beswick is always able to come up with parts diagrams for Yamaha's, but he never sent me the link to that site. Not much help for service specs anyway. Surely you can still buy a manual from Yamaha for this model? Not that old really, in the absolute sense, and the 600 was a multi-year non-grey import; they should be out there. Gary Ball has all the club's Yamaha manuals, you two were both at the last meeting; hopefully if that scenario arises again, we can find out what the breadth and depth of that part of the collection is directly.
