Update:
Got it all cleaned up. Carbs are ready to be put back together and bench synced. Found a set of side covers in the attic.
Going to try to revive the carb boots this weekend. Have another set in the closet, but they aren't particularly soft either. Got the tank sitting full of white vinegar, has already loosened all the rust from the inside. Needs to rebuild petcock though.
Ordered a TON of part from 4 into 1. Also bought a 4 into 1 yoshi replica from Chris at motogpwerks
He said if I keep the stock air box I should up 2 sizes in the mains. Sound about right?
Parts on the way:
Clutch, stator, transmission, cam tensioner, and oil pan gaskets
New Honda mirrors left and right
Solid state regulator/rectifier
Pro Motion Cable Set
Brake Master Cylinder Diaphragm
Gas tank rubber holder
Exhaust gaskets
Fuel line
Rim Strips and Tubes
Brand new caliper body, piston, and bleeder valve (going to fix the original for a dual disc down the road)
and other various tidbits...
