Good on you for putting that back on the road.
From the look of you in that old photo, you must have been under 18 when you got that bike. I can't imagine having one of those early ones as a first bike.
I've got a 1975 H1 that I bought new sitting in pieces scattered around my garage and barn.
I've decided to pass it off to someone who can put a higher priority on restoring it than me. Includes a spare rolling chassis, two spare engines (both needing complete teardown) a collection of NOS parts purchased over a period of several years, a spare exhaust system. The original engine includes new 0.5mm over pistons (not installed), and probably needs a crank rebuild to renew the seals.
I want to sell it as a complete collection, and I don't want to have to package it for shipping, so you'd need to come to Oregon to get it.
