!978 GS750 FB market place purchased for $500. Came with the carbs (Carbs are JUNK) and stock airbox and filter. Been sitting outside for some time now. Mileage on the speedo is 16,423. Gas tank looks great inside. I believe it's got good bones to work with.

That's a '77, wire wheels and single disk - registered in '78. Looks in really good shape. You're going to have some fun there!

Manufacturers tag on the neck says 8 of 78. Kinda late in the year to be a 77 but then again, I'm no expert.

A PO prolly switched out the wheels... there's little else different from '77-'79.

"78" had both "E" (cast wheels) and "standard" (spoke wheel) models. Paint has me confused, thought "78" paint was either maroon or dark blue for the spoked wheel models. Not sure about the red on Bobby's bike.

Better add black to those colors!

Hard to remember that long ago but for sure one spoked wheel color was blue, a neighbor down the road still has the one he bought new, while I was with him, and almost sure he had the option of maroon. Thinking maybe the "E" model was in black... You're straining my memory.

You may be thinking of the '78 GS1000C colors??? They were available in blue and maroon, along with the black GS1000E "skunk".

I checked the garage and the '78 GS750E is still black!

Sorry, I just edited post # 6

The carbs were junk and this is what I found in the clutch basket!! No water in the oil but this bike was last clutched in 1992 and has been sitting outside ever sense.

I'm ready for the challenge, a little more needed than expected.

Keep your head up...and keep pushing forward. The early 2V 750 engine is supremely durable, and once you sort though the teething problems, you will be rewarded...

That's looks like a good project right there, congrats!

Yeah Ed, after close inspection of the engine, it doesn't look like it's ever been apart. Oil pan is coming off in the next bit and we'll see what that looks like. The clutch was stuck in the compressed position so the springs had been compressed for about 30 years. Springs were 1mm (.035) out of service spec. (too short) $18 and problem solved.
After I get the engine running I will do a complete tear down and resto on the GS. I love this stuff.

What you're looking at is "I Have To Take the Engine Apart"

No metal but a lot of water and microbes that can live in water. Something didn't look right in #4 so I took the head off to see what didn't look right.
#1 and 4 pistons were down for 30 years and more condensation build up in those 2 cyls, but I should be able to correct it with the proper hone.
This bike has had maybe 4 oil changes in the last 46 years.
