79 XS1100 special - tire replacement - are these tube or tubeless type wheels?

[OldGreyBeast]

Hi all,

I'm finally replacing the 80s tires on my XS1100 with some new ones. The front tire that was on it had a tube in there. These wheels don't /look/ like tube type wheels but googling it I get mixed results. Are these meant to have a tube?

I tried to get a picture for you, but I cannot get one you can see. Inside one of the spokes you’ll find “SUITABLE FOR TUBELESS TIRES” cast or stamped into the metal in large print. Yamaha XS bikes started getting the tubeless wheels in 1979 as I recall. Not marked? They came with tubes. Somewhere in this forum the subject has been discussed in depth and detail.

The original tires on a '79 Special were tubeless.

If the rims are original, you can see the word "tubeless" cast into the wheel.

Ok it does say tubeless on the wheel. The valve stem hole seems to be much thicker/deeper than the modern ones. Is there a special valve stem for these?

Have you had any luck with fabricating those rubber parts we asked about a while back?

Hah, now it makes sense! Down in the specs it clearly says Is universal fit: No It's no wonder I couldn't find one that worked!
