Just picked up a 2008 gas gas 250. Delighted to see old owner had kindly fitted a new X11. Gutted then to see that he had also drilled the rim and fitted a rim lock and tube. I'm guessing he had leaky rim tape and couldn't be bothered to fix it. I want to go back to tubeless as I find tubed tyres a real faff. But I'm left with a hole in the rim. I could try a chemical metal repair (pb weld) but I'm wondering if rim flex would just ping it off ? Or I could put a 2nd valve in the hole to replace the rim lock. Any suggestions ?

Also where do you find the rim tape for tubless rear wheels which hasn't got the built in valve? Seems dapht to spend £25 on a built in valve and rim tape if I then have to put another hole in I for the second valve.

I would buy the correct rim tape for trial tyres and plug the hole in your wheel.

 

There are special plugs available for rim holes.

Well I never. I had no idea rim plugs existed. Cant seem to buy them in the UK. Anybody know where I can get them from here ?

The wedge ring will seal the air in the tyre. You can plug the extra holes with anything. It just has to keep the water out to avoid corrosion under the wedge ring. Neutral cure silicone rubber would do the job

Or. spotlessly clean the rim, then use a thick bead of Tiger Seal to seal the spokes.

Yes I saw that. They are not in the UK. I'm not paying £20.00 postage for a plug costing £3.00. Cant see any uk sellers

I put another tubeless valve in mine, many years ago

 

The tapes with valves are much better.

As above seal hole with silicone to keep out dirt
