Need help identifying this motor.

[Guest]

I got this gs750 a few months ago and have been working on it some, fixing what the previous owner messed up. He had to get a new title for it and the title says 1983 but there are other parts on it, carbs, 4 to 1, etc. Haven't had any luck looking up the Vin or engine number on any websites. Can someone please help me determine the year and engine model? I need to know before I get into ordering parts what my Avenue should be. The engine number is GS75X-106909 and I'll attach a picture. Hope someone can help. I wanna put gs1100e cams in and upgrade from the Mac exhaust, tune the carbs and a sprocket kit and chain for a little hotter street able bike.

That is an L model, 80-82 750 motor, unless there was an L model in 83. If you want to make it a better bike, put an 1100 motor in it.

Gotta LOVE the sticky tires.

Thanks Ray. I was thinking thats what it was but couldn't tell. I don't have quite the money to put a new motor in the way I wanna. I'm just gunna build the one I have and save some money. I have a machine shop and everything i need to do the work. I want to keep the 750 platform.

Ok but keep in mind that is the WORST engine Suzuki ever made & notorious for eating rod bearings. I know, I used to road race one. The 1100 engine will save you much headache down the line.

Dang really? I thought it was one of the best? Then again I have read a lot about how the cost cutting techniques they implemented around this time started turning their bikes into complete ****. I figure if I'm going to get into the engine I could replace some things anyways. I'f I can find a 1000 for a decent price I'll definitely reconsider but for now I gotta run what I brung.

I didn't think Suzuki made a 750 "L" with the 16 valve motor??

Possibly just not down there Hillsy?
Common enough here though.

Yeah - fair call.

I don't think Suzuki even sold the L models in Oz - all the ones I've seen down here have been imports.

Wait what? 16 valve?

The motor in the pic the OP posted is a 16 valve motor.

OH ok, thanks. Really that's all I was needing to figure out, but judging from what I'm hearing about this motor I don't think I'm going to be doing any real engine mods. I'd hate to spend $1500 on motor work just to drop a bearing and have to start all over again.

Especially when you can find 1100 motors for less than that.

Well everything I'm seeing says there was no L motor in 81, 82, 83. It would have to be an E to be a 16 valve. which still doesnt help me

Edit: It was the GSX that had a 16V head

I don't know where you're looking but I can't seem to find an 1100 anywhere for less that I could get a whole bike. Those engines aren't exactly a hot commodity and most people don't wanna give em up!
