Can it be done? Or new wheels is the only solution? Thanks

Yes.

Either guy some Stans or Joes rim strips and some sealant or butcher a 20" tube to fit and fill with Art Latex.

I've done a few sets with Stan's standard kits.

Sounds good guys! A friend of mine has his 4th puncture on an equal amount of rides so he is a bit fed up, just not ready to splash on a new pair of wheels yet!

Eclipse (DT) kit works well on a 317 for me.

20" tube poverty job did it for me

+1 for the Eclipse kit on a 317 (and a 717): has been fine for me too, for 12 months (no punctures either).

317 with tape recommended by reggiegasket, worked very well, thanks reggie.

Then tape twice over the cut out valve (I use threaded ones you can screw on) cut hole to let air in and jobs a good un.

I have done the gaffa tape method, but to just be able to wack on tape, keeping wheel in frame makes the job so much faster and easier. It sits well below the rim bead hooks, even at the valve, which I cut quite narrow. 20" tube method is easier to do, but makes changing tyres a faff.

A tubeless valve and some Duck tape did it for me.

Clean n easy.

anyone know of anywhere else that sells that tape?

i can't even see the link – ebay banned from work!

If you do punture or burp a tyre using the tape method, how quick is it to sling a normal tube in if you are racing for example?
