Hey, Fellas! Court and I are working on our bikes, both 80SGs, and there are some very interesting differences in the carbs. Court has posted some questions, but I now have some data re: my jet sizes etc.
They are the newer carb body, in fact carbs 2 and 3 have "3U900 E9Z2" stamped on them. They have the plastic floats, newer drain bowls, original metal needle valve/seat combination.
Court's carbs have viton tips and wire keepers on his needle valves, so we figure his carbs have been rebuilt.
My carbs 1-4 are all the same:
Main jets 137.5 (same as 79 SF)
Pilot Jets 45 (can't find any year with them)
Air pilot jets 185 (80 SG specs)
I have been searching all kinds of combinations, and have yet to find that setup.
The bike ran strong when last running.*
My question: Is it possible this is all factory, or has someone been playing with the setup? I am running the standard airbox, btw.
Thanks for any help/ideas.
