Tire Changing Woes - '78 GL1000

Postby lmcclure136 » Mon Jun 02, 2014 9:26 am



I love my GL 1000, and I try to be self-sufficient with it and love to work on it myself. I am really frustrated with a recent tire issue. The last time I put on a new rear tire (and tube), I had no problems. Well, it is that time again, and I ordered a tire, bought a new tube, and changed it out, only to have it leaking around the valve stem. Thinking I maybe had a bad tube, I tried another one, same problem. By the third, I tried to be extra, extra careful when mounting the tire, and wiggled the valve stem a little before tightening down the locking nut to make sure nothing was pinched. It held air, I took it for a short ride, and the next morning it was still fine. I took off yesterday for a longer rode, and got about an hour and a half out and my tire was flat. Airing it up, I had the same issue again! I can't see anywhere on the tire that I rode over anything, so I can only assume it has to do with the way I installed the tube. How can this be? Now it is sitting in the parking lot of a shop an hour and a half from home, and I was stranded on a Sunday with no place open and no extra tube with me. I am afraid to change it now, because I don't want to do the same thing again!

I am not a dummy, and I don't give up easily, but what am I doing wrong? I can start to buy tires locally and have a shop change them I guess, but it bothers me that I am doing something wrong again and again, and I never had this issue before. I am 55, so maybe I lost the necessary brain cells to do this job correctly. Any suggestions?

There were 2 things that caught me...When I installed the new stuff,the pry bar I used caught a piece of the tube and cut it...the second was a mis-positioned rubber strap that protects the tube from the spoke nuts in the rim...One of them punctured the tube...
I'd pull the tube out and air it up a bit...locate where it's leaking...You should be able to determine why as soon as you see it...
I also add a bit of air to the tube before I roll the last bead on the rim.Just enough to inflate the tube.. Roll the last bead on and then wiggle the tire till the stem aligns straight out then secure the nut...
Take a few tools,air pump and a patch kit...This could be done right where it sets..At least I'd do it. :D

Thanks for the tips. I will do a little inspecting and see where I am going wrong. I have the comstar wheels, so there aren't any spoke nuts to deal with anyway. When the tire won't hold air I am not able to get it on the center stand by myself to take off the wheel. I guess I need to carry something to roll it up on to raise up the back when the tire if flat so I can get it on the stand and change it on the road....I usually try to carry a tube, but I used my last one.

In a pinch I've used the bicycle patch kit.scuff it,apply the glue,hold pressure on the patch for a couple of minutes.
You'll know more as soon as you get the tube out and aired up.
You can tell if its been pinched or a metal burr punctured it.

If you have the Comstar wheels and dont have to deal with spokes, why are you using a tube at all? Are they not tubeless rims? 8-)

As I understand it, these rims will almost always not seal completely, and a tube is needed, even with a tubeless tire. I'm just following in the steps of the previous owner and Randaak's blog. I guess I could try it without at this point.

The early Comstar wheels are not designated as tubeless. Some folks have successfully used them as tubeless. (There may be a mod necessary to fit the valve stem. Memory at work here)

Just a wild guess, but is it possible the tire is slipping on the bead seat and putting stress on the tube? When you put the tire on next, put a telltale mark on the tire and on the rim right next to it. That way you'll know if the tire is slipping - which would no doubt put stress on the valve stem.

I know a lot of people who run them tubeless.

I am not one of those people and never will be.

Just something that has always made me say no.

Great information everyone. I got the bike home last night and pulled the wheel off. I'll work on it tonight and post an update. I think sticking with a tube is the best way to go, but I need to have confidence when I put it in there that I can ride more than an hour and a half, so I have to get this figured out. Taking it in to get it done won't help me the next time I am stuck on the side of the road on a Sunday!

I also reviewed a bunch of videos on youtube about tire changing, just to see if I see anything that I am doing/not doing is mentioned. I see a lot of use of baby powder on the tube and inside the tire. Any problem with that? I also wonder if the actual tube size, if it was a little large or small would impact this. Both the tubes I had came from the same shop, and perhaps the size wasn't quite right...which might account for binding or slipping...but I'm just speculating here.

I'll keep you all posted, and thanks for helping out!

You've got something in there between the tube and the tire. Just because it's leaking around the valve stem doesn't mean that is where the problem is. In fact, since the wheels can be used as tubeless, you could have a puncture anywhere on the tube and the only place it can leak out will be around the valve stem.

I got the tube out, and there were two teeny tiny little aluminum chips inside the tire, and two teeny tiny little holes in the tube on the outside where it comes into contact with the inside of the tread on the tire. All I can figure is that those two little chips cut into the tube during the two hours or so that I was riding and did their thing. I will be much, much more careful this time around! I'm going to mount it tonight and air it up and let it sit, and assuming everything holds, hopefully tomorrow night get it out for a test. Thanks for all the help and suggestions.

If you can run it tubeless on a rear that is the way to go. A flat on the road with a tube can be a pita with some tires that do not want to break off the bead. A tire plug is much faster.

The aluminum seems to be a fingerprint of the failure. And since you are now expert at breaking the bead your brand of tire seems fine for continuing to use a tube.

I agree with Wingadmin regarding marking the stem on the tire. As if a tire moves on the rim the stem may tear. But at least for your last leak, that was not the case.

Let us know any other lessons you come up with.

You might want to smooth out the inside of the rim with sand paper or scotch brite where your tire tools damaged it. A good idea anytime you change the tire. Then use something to protect the rim from damage from the tools.

Yes, I did smooth it out. I got the tire mounted and aired up last night. Time for a test ride tonight. I'm a little leery of going too far from home for a bit, but I feel better knowing what I am pretty sure happened last time, and that I resolved the issue. Fingers are crossed, and I am hoping for some good riding this weekend! Thanks for all the help!

I think I damaged the rim when I mounted the tire last time, as I found two tiny little aluminum chips in the tire that matched up with the two tiny holes in the tube. I have since smoothed out the rim and am hoping for the best as I venture out over the next couple of days...not too far from home.

I'm feeling pretty good about it, but I'll be listening for every little weird noise or change in handling for a while... It goes with the territory!
