Repairing a tubed tire along side the road is a PITA. The process is the same as on a bicycle but with larger spoons. Same patches will work.
It can be done without removing the wheel from the bike (try it on your bicycle) it isn't easy.
Laying the bike on it's side is a lot easier than trying to do it with the bike standing. It also makes it possible to remove the wheel if you have to.

 

This is worth a look.

It depends on how much you ride & how bullet proof you want to be, I had 150K on spoke rims without a flat. I did say had, I got 2 flats within 2 weeks last year, the first one I used my towing ins & was able to borrow a car to get a spare wheel & tire I had at home. That wasn't too bad since that tire was almost worn out, happened again about 10 days later & that time it ate up a brand new tire, I now have mags on my bike. There are a couple of places that can seal spoke rims, supposedly for life, but it isn't cheap. I can't imagine trying to do a tube repair on the side of the road withonly tools that you can carry in your saddlebags.

 

Flats scare the crap outta me.
When I was a kid, me and my girl were riding a full dressed 750 Hondamatic. Not a huge bike by any means, but darn big at 65 mph with a blowout. I tried like crazy to keep it up and couldn't. Didn't help that it blew just as I set the cruise and was taking my hands off the handlebars.
I went skidding down the asphalt on my side and my girl sorta rode on top of me. By the time I stopped, I had road rash from my ankle to my waist and from my wrist to my shoulder. My girlfriend had a little patch of it on her forearm.
We were very lucky. No helmets, but at least we were wearing long pants and not shorts like a lot of them wear. The bike was totaled.
If you're going to ride, it's just something you have to get over. For months after that, I could swear that the front end on my new bike wobbled, but it didn't.
No one ever figured out why that tire blew out. It was a new tire. But one thing I never did was worry much about them. I'd check tread depth when I was thinking about it and had them changed when they needed changed. I NEVER bothered to check air pressure, alignment, wheel runout, etc, etc. And all that will cause problems if out of spec. Afterward, I checked tires and wheels meticulously and have yet to have another blowout. I'm still **** about it.
Not a single word of my post will help with your question about tube repairs. I guess I just relay my story so you all will take them tires seriously. It's life or death.

 

I blew out the rear on my Road Couch a couple of weeks ago. I was within 1 or 2 miles of the house so I just limped it home. Road in second gear as slow as I could go. That was one squishy ride. Hard to keep it on the road. I pulled over and checked when I first realized something was wrong. The tire was still fully on the rim, otherwise I wouldn't have tried riding with a flat. Still not too smart but stupid is as stupid does. I don't think I damaged the rim since the new tire rides smooth. I wouldn't want to go very far like that.

As far as recommendations for a repair kit go, your best bet is probably towing insurance. I change my own tires and even with a tire changing fixture, it ain't a whole lot of fun. Lots of extra tools required including a way to reinflate the tire.

 

Since you have the Slime compressor..... just buy the Slime sealant for tubed motorcycle tires. http://www.slime.com/shop/tire-sealant/

That will get you to a shop to have a new tube put in.

 

I don't see anywhere that it can be used in a tubed tire, near the bottom it says "can be used in a tubeless motorcycle tire".

 

I used it on my wife's Dyna once, and it got her 80 miles to a shop for a tube replacement.

That's a different link. I'm glad it worked for you & your wife, it might work some of the time, but since a tube often rips after being punctured it won't work every time. It would still be good to carry, you might get lucky, I would ride very cautiously till it was replaced.

 

On a bagger, you might be able to get the right angle to insert it in the front tire, but the rear tire, you'd be SOL.
