My 1977 GS750 is complete!

[Bobbys 94]

FB purchase for $200 a few months ago. Apparently, it was owned by someone that took very good care of this bike until about 1986 when they removed all the engine side covers and carb covers to get them coated. Something must have happened after they where removed because they where left off until I purchased it a few months ago after 38 years of sitting without the covers installed. I don't know the whole story I'm just assuming what may have happened. The original owner past about 30 years ago and his wife gave this bike to her deceased husbands best friend about 15 years ago.
The picture below is the one I saw on FB market place. I asked the guy I bought it from if he'd tried to sell it before and he said no one wanted it because the engine and transmission were not connected anymore internally! Notice that there's NO clutch assembly shown in the picture, the part that connects the engine to the tranny. By the way, he had the clutch assembly in a tote in his shed.

OOhhh, resurrection of old memories. My 1st "REAL" bike was a "77" GS750 (the faster red one), a neighbor had the blue. I can only imagine the hr.'s you've invested. Now sit back & enjoy the benefits... Thanks for rescuing it... Great job.

"I" my friend, deg to biffer with you on the faster color in the 77 GS750 line up. And thank you for the compliments on my labor, it was as much fun as I've had in a while. Looking forward to my next in line.

Thank you Big Block

Thank you. I've owned and rode many bikes in my 70 years of life and this GS750 and my 80 model GS550 have been the only two that I can see anything in my mirrors without distortion. Great bikes and when people figure that out you won't be able to find a "Good Bones" bike for cheap anymore.

The GS750 was my second Suzuki and first 4-cylinder. First bike I did engine performance modifications on -big bored to 819cc using stock 1.0mm o/s GS425 pistons and rings for a 3mm over-bore. Loved that bike.

Excellent restoration, Bobby!
Glad that it ended up in your mitts because the VAST majority of the buyers would have scrapped it or parted it out.
You should enter that beauty for "Bike of the Month" consideration.

$200 spent on the 77 GS750 on FB. Approx. 200 hours of my free labor and about $850 in parts and pieces. The list is as follows:

Rebuilt components include

Both calipers
Both master cylinders
Front forks
Swingarm
4-VM26 carburetors (K&L Kits)
All fuel pipes between carbs
Oil pan removed and cleaned (I highly recommend this on older machines)

Replaced components are as follows:

Spark plugs
Battery and cables
Petcock
All fuel lines
Air filter
Front brake hoses
F & R brake pads
F & R tires, tubes and rim strips, Dunlop tires
F & R wheel bearings and seals
All outer engine covers and gaskets
Stator assembly + added Dyna S ignition
Carb covers and bowls with gaskets
Clutch friction plates
Shift shaft seal
Oil and filter changed twice within 6 miles
No master link chain and both sprockets. (a bear to install a freshly painted swingarm)

As I've said before, You have to do this because you're passionate about it. 200 hours of labor that if you had to pay for is about 20k.
This machine in concours condition might bring 4k, maybe.

My cash out of pocket is about $1,050 and I would/will do it again in a heartbeat.

Notice in the pic the condition of the exhaust when I first saw it in the guys shed. Completely covered in surface rust.

 

[Bobbys 94]

Now look at the final result of my cleaning the surface rust off. The entire exhaust was covered in surface rust.

 

[Bobbys 94]

Picture below is the "Miricale" stuff used to clean the surface rust. It was designed to clean surface imperfections off of blued gun parts. I use it all the time restoring pre WW2 Winchester Lever guns. Doesn't harm the original bluing on the old firearm.
I use it along with WD40 and elbow grease.
Note that I soaked the exhaust in WD40 for a couple weeks before trying to remove the surface rust.

"If the rust has penetrated the chrome down to the metal, this stuff will Not fix that"

Steel wool and or scotchbrite will leave scratches on the chrome, this stuff does not.

Nice find and beautiful restoration.

Thanks for the heads-upon that product. Never heard of it.
Have used 0000 steel wool and Autosol with decent results. Might give this one a try.
