Tu be or not Tube. That is the question.

what about running tubeless in an older (79) with mag wheels? has anyone done it?

i have no problems with my tires now...i'm assuming they're tubed. i'm just curious though.

The first bike I used tubeless tires on that weren't stamped tubeless was a "79" GS 1000 S. Never a problem. I would like to hear from anyone who has tried tubeless on wheels not stamped tubeless and had a problem. Wondering what kind of problems it could cause. I'm surely not an expert, but I have a feeling that the idea that a wheel should be mounted with a tube unless the wheel is stamped tubeless is a myth, sort of like the myth that when rotating the radial tires on a car, you shouldn't reverse the rotation cause it would mess up the belts.

It could well be a myth, and I'll join you in your desire to find out how true that is, or how mythical. I will not, however, be the guinea pig to find out. Let someone else experiment. :wink:

Tubes or no tubes

Tubes or no tubes

I asked this very question about a month ago.

1978 gs1000E with mag wheels

Up until now I have always kept the tubes in.

The general consensus here was not to keep the tubes in,
so this time I went without the tubes.

If you scroll down or use search you can read the replies to my
posts.

Took the bike out yesterday for a good 100 mile ride, felt fine.

OK, here is the lowdown on using, or not using tubes in wheels not marked tubeless.
when they first came out with the cast wheels, they had problems with the wheels leaking air out due to porousness of the metal used at the time, not all of the wheels leaked, but enough did to be a problem.
this is why Honda used the com-star wheels, that are made up out of stamped metal and not cast, Honda wasn't confidant with casting technology at the time.
the majority of pre-82 Suzuki cast wheels don't leak enough to be a problem and can run without tubes, I don't have tubes in my 80 1000g and my bike holds air better than my new car!

some other makes of bikes had more problems with their wheels leaking, Acura has even had problems with oil leaking through the block of their early V6's!!
Suzuki started to use a different technique of casting wheels in 82 and cured the air leak problem, though a occasional casting error still does pop up from time to time.
 
Thanks focus, great imfo. I've searched everywhere I could think of trying to find facts like this, but I found nothing. Did the place this imfo came from happen to tell why an "80" 1100 E would have a tubeless rim on one end but not on the other? Matter of fact, my "83" 1100 E has the original wheels on it. The rear is stamped "tubeless" but the front is not. This really seems odd, since the casting change came in "82". It still seems strange that any motorcycle mfg. would put tubeless on one end, but not on the other end, Suzuki did it for at least 4 years, yet in these same 4 years some of the exact same model bikes had tubeless on both ends. Great imfo, but still rather confusing.
 
it gave a margin of safety to keep using a tube in the front wheel.
early cast wheels were magnesium aluminum mix and were somewhat brittle, it was safer to put a tube in to protect against sudden deflation if a big hole was hit and cracked the wheel

Nick hit the nail on the head. The rear is stamped "tubeless" and the rear is not. It's a 1980 GS850L (shaftie).

Thanks,

Is it odd you can run tubeless on one end? Cars require on e or the other all the way around usually :?:
