Hi guys! My name is Chip, I'm from Birmingham UK. I've inherited this beauty from my late father and decided to restore it . I filmed everything and will be posting every wednesday evening on youtube here: playlist I finished the restoring process appart from finding new piston rings, uppon assembly i found out that the old rings were pretty worn out...2.5 bar on a compression test a,d found out that the pressure is lost past the piston rings in the oil sump, the loss is 80%, the engine starts and runs but i'd like to find new rings and replace them. heeelp! i can't find new rings anywhere. the engine name is GJ71A some pictures before and after restoring it: I loved this bike ever since i was a kid, I'd like to restore it and ride it as it is with minimal modifications.
