results of my Ducati/Mikuni day...these much improved, I project will be fully functional. Have yet to "rerack" them.
Some orings were near crystallized (original?) I believe these were never fully serviced in their 25 year lifespan.
EVERY oring, seal, circuit, float system, fuel pathway.....all have been renewed/replaced/addressed. Jetting tweaks and setup per owners specific wants/needs. As old as they are, they'll now go another 25!
Somehow, I think Jennings would give a nod of approval! And @
Ram Jet too?
