We had planned to do some light maintenance and finish with the inspection, but…
things haven’t been going smoothly lately, really (‘ω’)
Since the bike is getting older, some issues are inevitable, but… I’d like things to go more smoothly, you know?
I’ve been cutting back on work quite a bit lately, so I’m barely managing to keep up… or maybe not, it’s hard to say.
We finished up the top and bottom, so it looks really clean now.
That sediment-like carbon stuff… what is that anyway? It’s really gross.
We drained the fuel and checked inside with an endoscope…
And wow… it was incredibly clean. It looked brand new—I was surprised! The tank’s condition was great. We’ll wax the inside of the tank too.
We’ll use a genuine Mikuni float valve from the GSX1100S.
We confirmed the actual oil level and we’re done (‘ω’)ノ
It’s good to check anything that’s listed in the manual.
We use Yoshimura 877-260-1207 fuel hose as our go-to.
We remove the plugs and crank it over properly to prepare.
The plugs were completely clean, so we’ll reuse them as is.
We’ll sync the carburetors and that wraps it up.
The battery is a Pro Select AGM gel battery for the GS1000—here’s the one we used.
It’s a good idea to label it with the replacement date.
The main ground on bikes from this era has an interesting structure, or rather… honestly it’s not great.
In modern bikes (mostly), the harness ground branches directly from the main ground.
But on the GS1000 and similar bikes, the battery main ground and harness ground are separate, which is a bit of a hassle.
Can you see it? The black and white wire. Those thin wires are grounded to the frame (steel) all over the place.
Actually, this can cause problems sometimes. It’s more reliable to ground everything to the aluminum (engine) if possible.
We reinforced it with something a bit thicker—maybe 1.25 SQ?
Ideally we’d remake the main ground, but for now we’re just getting by…
We changed the engine oil to Shell Advance Ultra 15W-50.
We changed the brake fluid to Golden Cruiser DOT4.
It shoots out with a pop, so we added a float.
Maintenance becomes super efficient!
It looks almost stock, but there’s subtle work done on it—a sophisticated build.
Those gourd-shaped Brembo brakes still look so cool—just watch out for cracks (‘ω’)ノ
Next up is the inspection and test ride to finish!
