Brought this '77 Suzuki GS750B home 5 years ago... stock aside from a MAC GS1100 exhaust that hung way too low, and a 78 humped seat. Carbs not rejetted, battery shot, Kendall Challenger 110/90-18 looked to have had endless burnouts done to it... clunky 630 chain about wore out, bearings needing overhaul, carbs dirty with bad orings, rattle can paint job, weeping head gasket @ typical cam chain tunnel @ front... $725 & still ran like mad when opened up!
1st season on it was late August through Dec 1st, by which time I was really out-riding the tires and front 295mm single piston brake...
Slowly over 5 years, only stock things left were the frame, wiring harness, handlebar controls, rear master cylinder, and battery box! It is still somewhat stock cosmeticallyappearing, as I've used numerous parts off of other Suzuki models as very thought out upgrades, but the bike is vastly improved...

Im forgetting a lot...
Built for Apallachian hills & mountains twisties, corner burner, 50 lbs lighter than stock... I love the twisties of SE Ohio, Kentucky, & West Virginia! Bike out handles a lot of newer bikes. My ninja 600 buddy is the only one really able to hang, even surpasses ZRX1100's with $$$ tires...
