The rim sealing band over the spokes probably got dislodged or damaged. It MUST sit in the groove perfectly and seal along the side grooves. It must have no holes!

Take it back apart and have a look! These things are critical.

:D

And yes, it does!

Take out valve and rim tape, clean rim tape in soapy water, thoroughly clean the rim, apply grease over the spoke ends and a very small ammount(too much and the tape will not seat correctly) to rim where tape sits. Reassemble, the tape will locate in the grooves easily and as long as the rim tape was in good condition it will not leak.

Only seven? There is a learning curve to these things.

Next problem you may encounter is a corroded valve stem whwn you disassemble to clean things. If it is screwed, order a new rim band with incorporated valve from the Tryalshop. Hopefully your rim cleans up ok and is not too badly corroded to seal in the lip areas on both sides of the groove! :D

As a temporary fix make sure all the spokes are tightened then apply a little rubber solution(that stuff you fix patches to inner tubes with), at the bottom of each spoke. Doesn't stop it entirely but it does slow it enough for it not to be too much of a problem until you get a new tyre and can fix it permanently.

If you have that 3mm spacer in the valve stem where it goes throu the rubber, you can take it out so that the inner washer around the stem seals tighter. Just do not overtighten the outer nut!

Once again, the fit of the rubber against the outside of the groove is the most critical.

I use a dab of DC111 silecon paste on the nipples to keep water out and help prevent corrosion. And a a professional tire lube on the band and tire, although a heavy mix of dish soap will work. Slick as snot! The band will just fall into the groove, almost, ck every cm of it for a perfect seal! :D

my valve stem has to be quite tight(tighter than i want it to be) or it will leak. i dont know what you mean by the 3mm spacer or where it is. there are 2 rubber things on my valve stem, one on the inside and the other on the out side. the rim tape is centered but still leaks from a few spokes. i believe this to be because of the valve stem. the rubber thing on the inside of the rim is much smaller than the original valve stem's. i believe the old valve stem was a 2007 year model and the one i have is a new 08 type. i believe the inner rubber thingy is letting a bit of air past under the rim tape.

There is a close up pic of what I call a normal valve stem HERE

I have no ider what GasGas is currently using, but the band with integrated stem from Tryalsshop or BRX may be your best bet. I hate them things anyway! :thumbup:

Actually, that will probably be my next spares purchase as well, just so I do not have to go through what you are now!

GasGas has a new integrated stem/rim strap that is one-piece and the part # is BT551502808.

I rebuild both wheels on my '07 in the spring, and even had second thoughts about the rimband. My stem was heavily corroded and had to go. The hole in the band was iffy (this is from factory) and even though I had a new band on hand did not use it. The new band has a hole punched that is tighter than a ducks ass. You need to stretch it to get the stem through.

Anyway, even with everything in pretty good shape, I had to go back and remove the spacer thing to get a good seal. Morale of this story is that if things are not perfect, they will not seal, yet there are options.

Lazy peeps just stuff a tube in them! Whatever works for you! Oh well! :thumbup:
