Progress update: Found a NOS tank for the KZ650 so now is pretty much perfect (for it's age, like a lot of us!). Just got the GS650 started today. New wiring harness, cleaned carbs, etc. etc. Now I have a LOT of sanding on the tin/plastic to get it ready for paint. Will probably wait until warmer weather to paint though. I did love the paint job on Dave's project bike. Either need to contact his painter or try to get close to that myself (slim chance, not that great a painter).
