hi guys ,,, its like this,,, i recently removed my old front tubeless tyre 100/90x19,,, which had been on there for 8 years ... it was starting to decay,,,, it didn,t look good,,, so i purchased a new bridgestone V100/90x19,,, which when pumped up would like thinner ,,,which is what i wanted .. ,,the rim is embossed ,,, tubeless ,, so i put the tyre on in the correct direction, and used soapy water around the tyre and rim ,, ,,but it still keeps going down,, ............i,ve pumped it up regularly 8-8 times and after about 1 hour it starts to go flat haven,t even ridden it yet ,,ant help would be great regards oldgrumpy... sorry its a 1980 gs1000e

Get a tube.
AFAIK there is no such bike as an '80 GS1000E, maybe its a 79 or an 1100E?

Tire valve stem is probably your problem. I had the same thing happen to me. I now put new one in when I replace my tires.

Yes, There is an 80 GS 1000

Grumpy - I'm guessing the rim has some old tire stuck on the bead, so you may have to scrub that off to get it to seat

You can't find a spot where it's leaking after you pump it up?

This stuff should fix it. It had worked for me several times. Don't put too much in though. Take the wheel off, put a small amount in, just enough so it'll run around inside the tire, then pump up the tire and tilt it in all directions specially around the bead.
If you put too much in it will unbalance the tire and then you can't get it out again without removing the tire!

Spray some dish soap and water around to see where it's leaking.

I would suspect the valve stem or like B T said crud and debris on the rim. I had the same problem on my 650g. I changed the stem and it still leaked. Took the tire off and cleaned and sanded the rim with 220 grit sand paper till it was real nice and smmoth where the bead meets the rim. No problems for the past 3 years. Cheer up!

I agree with getting a tube.
But you might want to rethink about the fact there isn't a '80 GS1000E.
They looked like this. Slotted disks, non-stepped seat, CV carbs, newer hand controls. Think the front brake reservoir is different also. Beautiful bike isn't it?

rims also can corrode and causes a leak at the bead. My GS750E got progressively worse with leaking till I pulled the tire and scrubbed down the corrosion to get a clean seal.

[JEEPRUSTY]

I too have suffered the ignominy of corrosion.
Pop off the tire and scrub the rim clean.
replace the whole valve stem as well cos its damn near time.

I agree on a redo. It is a brand new tyre, something went wrong on the install. Time to start over from the beginning.

Hey that looks an awful lot like my 1980 GS1000E.
Have you checked with the soapy water to find where the tire is leaking? I would guess valve, bit it could also be the seal at the rim. We can all guess but only you can find out.
