Done that, just no options that I can find in the 130/90/18 that I can come across other than the Kenda challenger and the shinko 230 tour master
How wide is your rear wheel? In order to run a 130 the wheel needs to be at least 2.50 wide.
Yeah, I say the Kendas suck in the rain. They also suck in the dry. A few others here have experienced these things, and the word is pretty uniform that they're only useful as rim protectors.
Anyway, the Shinko 230 is an outstanding tire in all conditions and crazy cheap. Just not very long-lived.
Also, exactly what bike are we discussing here, what rear wheel are you using, and what bike did it come from?
Stock on the 1978 GS1100E was an 17" cast wheel 2.5 inches wide wearing a 4.50-17. That converts most closely to 120/90-17 in modern sizes, but there are only one or two options in that size. Most folks run 130/90-17 just fine; it's easily available in a variety of brands.
So if you have an 18" rear or some other bike, let's sort out what you have before we pick a tire.
Yup. And even if it's 2.50 wide, 120/90-18 would probably work a little better and would give you a LOT of good choices.
If you're using some even wider wheel you found somewhere, then 130/80-18 would also give you a lot more good choices.

I have a 1978 GS1000 with lester mag wheels 19 in front and 18 in rear, the rimes a 2.75 wide I believe. I was referring to this particular rear wheel not having much options for tires. I currently have a 130/80/18 on the rear. May go shinko 230's

Its a lester mag 18 i believe 2.75 wide
In that case you should be fine with a 130/80-18, which opens up a wide range of options; 130/90-18 is pretty rare. You could also use a 120/90-18 if you want to quicken the steering a bit, although the front tire has a bigger effect on that.
This is a pretty decent chart, although you have to scroll pretty far to get to the rear wheels:

Some tire manufacturers have tire spec charts online giving recommended rim width ranges.

appreciate the response, I have considered 120 on the rear, but it just seems hard for me to want to go smaller, what front would you consider running? right now I have a 90/90, but looking to go to a 100/90/19, would you seen any benefit to going to a 100/80/19? I am all for making the steering quicker, coming off a sportbike, I am trying to make this thing handle as good as it can for what it is.
How wide is your front wheel?
I'd lean toward the 100/90-19; that's well-known to work very well on that bike and darn near every GS for that matter. The 90/90 was mostly used on the smaller models, and restricts your tire choices quite a bit.
Many GS models did end up wearing 110/90-19 fronts over time for reasons unknown (probably just what some shop needed to get rid of...), but the difference in handling between a 110 and a 100 is dramatic; the 100/90-19 handles far, far better and the 110 turns a GS into a pig.
That said, I'm not at all sure what the difference might be between a 100/90-19 and a 100/80-19. The Shinkos are certainly cheap enough to experiment, but unless the front wheel is significantly wider than stock, I doubt it would improve things.

What he says.
I thought I'd scored a bargain at a local autojumble when I walked away with two front tyres for a pittance. Brand new Dunlops but just slightly oversized.
Humph. Being a stubborn sort I got the mileage out of the first one and gave the second one away.
The understeering was... interesting.
I got used to it but I certainly didn't want to repeat it, so the next tyre on that bike was a proper size.
