Alright, let’s talk about this 1981 Suzuki GS750L motorcycle, you know, the one everyone’s been yapping about. I ain’t no expert, mind you, but I’ve heard a thing or two, and I’ll tell ya what I know.

First off, this here bike, it’s a Suzuki. Suzuki, that’s the name, like the cars, but this one’s got two wheels, not four. And it’s a GS750L. Now, what’s that mean? Well, the “GS” part, that’s like sayin’ it’s a regular street bike, nothin’ fancy, just somethin’ to get ya from here to there. And the “750”, well, that’s how big the engine is, kinda like how you got a big pot and a small pot, this one’s a 750 pot.
This 1981 model, they call it a “custom styled” bike. That means it’s got them high handlebars, ya know, the ones that make ya sit up straight like a king, and a comfy seat, not one of them hard, skinny things that’ll make your backside sore. It’s got a four-cylinder engine, that means it’s got four of them…thingamajigs…inside that make it go. And it’s a four-stroke, which I guess is better than a two-stroke, though I couldn’t tell ya why.
Now, some folks are all fired up about these “engine codes.” They wanna know all the little numbers and letters that tell ya exactly what’s inside that engine. Me? I don’t care much for that. But if you’re one of them code-crackers, you gotta look at the VIN number. That’s like the bike’s secret code, tells ya everything about it. Somewhere in that mess of numbers and letters, there’s a code that says what kind of bike it is and when they made it.
- They say this engine’s got somethin’ called DOHC. Don’t ask me what that means, sounds fancy though.
- And it’s got four valves for each of them…cylinder things. More valves, more power, I guess.
- Some folks say it’s got titanium valves, that fancy metal they use for spaceships and such. Makes ‘em strong, I reckon.
They made these bikes back in ’79 and ’80 too, but this here one’s from ’81. Same kinda bike, mostly, but maybe a little different here and there. They got this fancy liquid-cooled thing, keeps the engine from gettin’ too hot. And they got these holes that connect between the cylinders, somethin’ about ventilation. Sounds like they’re breathin’ better, which I guess is good for an engine.
Now, some folks are lookin’ for a service manual. That’s like a book that tells ya how to fix the thing when it breaks, which, let’s be honest, it probably will. Finding one of them books, well, that can be a chore. You gotta look around, ask around, maybe go online, though I ain’t too good with that computer stuff.
Some fellas, they like to argue about whether this engine has eight valves or sixteen. Well, like I said, it’s got four valves per cylinder, and there’s four cylinders, so you do the math. Sixteen, I reckon, but who am I to say? I just ride ‘em, I don’t build ‘em.
And if you’re lookin’ to fix the valves, you’ll need these shim things. Little metal pieces, I guess. Gotta get the right size, or you’ll mess things up for sure. What size? Don’t ask me, I ain’t got a clue.
So, that’s the lowdown on this 1981 Suzuki GS750L, as best as I can tell ya. It’s a good bike, a strong bike, a bike that’ll get ya where you need to go. Just keep it oiled up, keep the gas tank full, and don’t go ridin’ it like a crazy fool. And if somethin’ breaks, well, find yourself a good mechanic, ’cause I ain’t fixin’ it for ya.
Remember to always check your local laws and regulations regarding motorcycle operation and maintenance. Safety first, folks!
