gs1000 cylinders

[Guest]

Are all years/ models of GS1000 cylinders the same? On my 1980 GS1000G I have a ring of rust on 1 cylinder that will not clean up without going oversize. My plan is to buy a set of jugs off Ebay with damaged fins and pull the sleeve and put in my cylinder. Also the sleeves do come out with heat yes?

The cylinder will come out with heat although I personally don't like the idea of changing a liner from one cylinder to another. If you are going to go through all the work, changing them - making sure all the liners are flush with the cylinders when they cool - just spend a few extra bucks or the extra time necessary to find a good deal on a set of decent cylinders and install those instead of dinking around.

Per Alpha Sports the 1980 GS1000G cylinders fit...

1979 SUZUKI GS1000LN *
1979 SUZUKI GS1000SN *
1980 SUZUKI GS1000ET *
1980 SUZUKI GS1000GLT
1980 SUZUKI GS1000GT
1980 SUZUKI GS1000ST *
1981 SUZUKI GS1000GLX
1981 SUZUKI GS1000GX

I'm not so certain the chain drive* models are the same as the shaft drive models. In fact I'm almost positive they aren't the same so to be safe stick with the cylinders from a shaft drive bike.

Thanks for the info. I'm so upside down in this damn thing any way I can save money right now without compromising my project is how it has to be.

The cylinder liners are matched to the aluminum cylinder with a color code, much like crank bearings are color coded in some sort of size reference. If, for example, you take a liner out of a yellow coded cylinder it may not fit in a red cylinder. I'm not sure how the colors are referenced, but I'd caution against trying to move liners around.

oval holes are worse than rusty holes.
hone your old stuff and give it a shot.
you would be shocked at what will work.

Man , I put a nasty gouge in my #3 cylinder from a rogue lower oil ring when my dumb ass tried reassembling the first time. I honed it a bit more a stuck it back together (with the best looking old one). It still makes 110psi! Granted its a bit lop-sided from its neighbors and made carb balancing a pain but it still runs like a raped ape....

I was not aware of the cylinder matching, I guess I'll just have to suck it up and buy good to go setup. My cylinder unfortunately has a ring that was rusted in it from sitting, as such the piston rings will be wiping over a ridge in the bore which I am sure will cause heavy wear or possible ring breakage. I have honed out .002" but the ridge is still there, seems fruitless to continue with this cylinder seeing the cost of gaskets is more than a good jug would be. I thought bringing an old Goldwing back to life was expensive, seems cheap compared to what this one has cost me...

Can you post a picture of the rust ring? I ask because I had a 1000 GS motor I got from a junkyard and the #2 had sitting ware in it, the rust ring was about 3/4 inch tall and a couple of inches long. I honed it and put new rings in it. Got 120 psi cranking out of it and raced that motor for well over a year with no issues.
