Thanks for the comments! Glad you all enjoyed it.
Regarding injector oil just used what was available regular 30 weight as i remember. Had to decoke heads periodically. Replaced chain part way so 2 chains total.
Sparkplugs, now that's a story. Had 2 freeze in the head. Since it had an extra spark plug hole in head the first time it happened i just put a new one in the extra hole. The second time it broke off so took head to machine shop in Iran and they bored it out, put in a sleeve threaded for plug. No more problems after that.
Other than replacing front tire twice, chain once, and several spark plugs eveything else was original including sprockets and shocks. Maybe changed points but don't remember.
