Great info so far guys. thank you.
The front end on the 77 is a bit of a mystery. Previous owner said it was a Vision front end.... except the Vision had trailing axle forks and a 18" wheel. This has center axle forks (37mm tube dia. 185mm center to center, XS is 34mm tube dia & 186mm center to center) & a 19" wheel. The only two Yamahas I know that used that wheel style were the Vision and the Seca 400. Seca 400 was a single disk in the US with an 18" wheel. I have seen pictures of dual disk Seca 400's but I assume they were non US models. I'll have to look at some old pictures. It might be a Seca 550 front end. I've never seen a dual disk Seca 550.
The front tire is a 100/90-19 and rubs ever so slightly on the fender. The fender looks like a Seca 400 fender to me. At first I thought "Aha! He installed a 100/90 tire instead of a 90/90 tire!" But the 19" wheel is a head scratcher for me. Need to stop relying on memory and find some pictures. I know the 650 & 750 Seca wheels are the swirl spokes.
I appreciate the info about the stock electrical system. After reading a couple threads I'm thinking of a Mike's XS wiring harness and then simplifying it into a consumer's wiring harness and a charging system harness as per the book The Yamaha XS 650 Engine by Hans J. Pahl. But I still need to do more research. I'll be pinging you guys more in the future.
Leaning heavily towards EX 500 carbs. I have some SV 650 switch gear laying around, I might use that. And in my imagination, my flat tracker seat might look good with a DR 650 rear fender and DRZ 250 tail light.
Need to research more, learn more and think more. Nice to have other running machines.
