1968 Yamaha YAS1C Twin 125cc
The old seat was totally rusted out. The foam and cover had been eaten by a mouse or rat. This is the old seat pan from a 1974 Yamaha DT100. I hacked the mounts off the old seat and welded them on to the "new" seat pan.
Won't win any awards, but it's better than what it was before. Probably going to rivet the vinyl in the corners.
This is how you know it's barn fresh.
New sealed battery, EBC brake shoes (thanks Benji!), Michelin Gazelle tires, tubes, and replaced some broken spokes. Oil pump has been bypassed, and seized steering dampener removed. No permanent modifications have been made.
