Title: Repairing A K75's Flat Rear Tire
Post by: Laitch on July 28, 2019, 04:06:50 AM
Ever repair a K75's flat, tubeless rear tire on a dirt road by yourself? Here's what will be helpful to get rolling again:
or
Rapid work is necessary. Get the water-applying system together next to the tire at the rear of the moto.If leakage is minimal, hit the road and get somewhere you can enjoy life while you're looking for a new tire and somebody to mount it, unless you have access to tire irons, zip ties and a high-pressure air compressor. Balancing can be done later.

That's tire repair—short form. Where do core and leg strength enter the picture? You'll need them when you realize that for reasons of gravity, or geological formation, you can't raise the moto onto the center stand. It could be the tire leaks too rapidly or that the ground is too soft. You'll need to tip the moto onto its right side so the wheel can be rotated or removed.

Here's where having the cases attached helps. A case will help to protect the rear indicator stem and help to lessen impact when the moto is lowered onto its right side. It will also serve as a fulcrum so you can rotate the wheel instead of needing to remove it.
The Internet is packed with videos of diminutive riders launching their motos into an upright position using the walk-backward technique. Most of the motos are cruisers with giant loop crashbars and handlebars the width of bull elk antlers and their seats were only about 18 inches from the ground before they were tipped anyway. Good luck with that.

Once the moto is upright, get a tire soon. The tire plug is probably not long for this world if it has been your first attempt at repair.

The alternative to these two methods of tire repair is to pay for AAA’s (or some other reliable provider's) motorcycle/recreational vehicle roadside assistance policy and call them up to deliver you unto salvation. That will give you 100 miles of free towing to the destination of your choice. You can call your parents, grandparents, peculiar uncle, repressed or uninhibited aunt, lover or lovers as the case may be, valet, guardian ad litem or lawyer for help arranging a salubrious outcome.

Today's ride brought these techniques to the forefront of my awareness. Order is out to American Moto Tire. Maybe I'll have it by Tuesday.

Excellent write up, as usual Laitch.
I carry repair plugs and a small 12V pump with me. Just hope that I never need them.

I have not so fond memories of repairing a flat on my Triumph in 90 degree heat. Tube and rim locks made it a bit more trouble.

Superb article, concise and authoritative. I give it 5.5 Monkey Nutz, only because it lacks notation if you're using strap-on's.
++ AAA, bonus is the A/C truck cab. Still carry repair kit, but it works better starting campfires with the plugs.

in my experience...

Check tire for roofing nail that used to reside on my garage floor
remove nail and plug hole (breaking fingernail before realizing pliers are in toolroll)
use all 3 CO2 cartridges to inflate to about 10psi
proceed slowly to a real air compressor

that 12v pump works great with a car battery but will drain your moto battery enough for a no start pretty quick, don't ask me how I know

I'll endeavor to memorize the tire repair outline in case I ever actually have to do that.

And Johnny -- you make tire repair look almost romantic in that idyllic landscape.  Why would anyone ever want to call AAA when you can meditate in the gravel under a blue sky!

Great pictorial. 10 more feet and you'd be working in the shade.

I have been incredibly lucky so far, but feel like I'm due.  I carry a stop and go tire kit and some of the worms along with a Honda labeled Slime compressor.

The new K100RS I just got has 18+ year old Metzlers on it that are going to be replaced.  I think I'll take an afternoon and punch some holes in them and see how the stuff I've been hauling around works to repair them.  Thinking about it, it's not a bad idea to practice doing tire repairs on a tire that's going to be replaced.  Glad this thread got me thinking about it.

What are the chances that a yahoo driving a beater while working through personal issues along a deserted back road by means of free-spirited acceleration coupled with ingestion of bath salt-laced Bulleit rye shots will notice a man wearing a dark shirt and dark pants bent over working on a dark moto in the shade?

I carry a light, reflective scream green mesh safety vest in my tankbag so I can shed my 10lb riding jacket and work in relative comfort and safety wearing it instead.

I'll endeavor to memorize the tire repair outline in case I ever actually have to do that.
Don't bother. Clearly, you have been anointed. Just give succor to those who must ream the living hell out of their tires to plug them. Shine your light upon them. Verily, carry spare batteries.
