Does Suzuki’s subdued charm shine through? GS750 Inspection – Engine Oil/Fluid Change – Tachometer Gear Oil Leak and More

This color scheme is my favorite among the GS750 lineup.
The thin blue and gold lines on the black tank are gorgeous.

I wish Suzuki would bring back bikes with this kind of aesthetic.
Are they moving away from neo-classic?

Since it’s just an inspection and light work, I’ll wrap this up quickly.

Engine oil is Shell Advance ONLY.

Recently I’ve been mixing 15W-50 with 10W-40 to adjust it as needed.
You wouldn’t notice the difference…

I’m also changing the oil filter, of course (*´ω`*)

Since I go to Izu Sky often, I’ll change the fluid.

If the fluid in the tank looks dirty, watch out.
It might mean it hasn’t been changed in quite a while.

This one is very clean, so I’m relieved!

Let’s fix the tachometer gear oil leak.

Both the Z and GS have mechanical tachometers that are really cool!
Since this work was requested quite a while ago, the parts are already in stock.
I just need to clean it and reassemble.

I wet-blasted it and replaced the oil seals and O-rings.
I’ve packed fluorine grease in the spots where we don’t want seeping but do want lubrication.

If it’s just seeping, no oil will actually leak out (*´ω`*)
I’ve also raised the shift lever by about 2mm as requested and adjusted it.
After charging the battery, I’ll take it for a test ride and we’re done!
