I don't personally own one but I'm trying to find this manual which I'm having my doubts it exists due to all the specific 1975 carb, engine, parts manuals that seem to make one big shop manual I'm guessing ? What I'm really after is the exact jetting specs for the 75 SST F/A 340 Mikuni carbs as installed at the factory. The 1975 carb manual shows all the jets with SnoJet part # that doesn't help me out very much.
