perce Posted September 18, 2005 Report Share Posted September 18, 2005 most likely it's coming out of the spokes Quote Link to comment Share on other sites More sharing options...
badass76 Posted September 18, 2005 Author Report Share Posted September 18, 2005 (edited) how can i tell if it is a tubeless rear? Edited September 18, 2005 by badass76 Quote Link to comment Share on other sites More sharing options...
lewis_gasgas Posted September 18, 2005 Report Share Posted September 18, 2005 Usually they say on the tyre if they are tubeless or not but someone could have plonked a innertube in it ? Like PERCE says its probably your spokes have you tightened them ? If not could try some sealer stuff. Quote Link to comment Share on other sites More sharing options...
bikespace Posted September 19, 2005 Report Share Posted September 19, 2005 Lick your finger and try to cover up the valve with it (nice), just to see if you've got a leak there. Otherwise, get it in the bath and watch for the bubbles. Good one to do while the other half is out Quote Link to comment Share on other sites More sharing options...
toofasttim Posted September 19, 2005 Report Share Posted September 19, 2005 Another possibility is that there's some grit between the bead and the rim. Quote Link to comment Share on other sites More sharing options...

How slow is very slow - does the tyre stay up during a trial but go flat when sitting in the shed during the week? If this is the case why wory about it, 5 minutes with a footpump on the morning of a trial and you are sorted - just a thought! Find the source of the leak and fix it when you either turn the tyre or fit a new one. Edited September 19, 2005 by g4321 Quote Link to comment Share on other sites More sharing options...
alan bechard Posted September 19, 2005 Report Share Posted September 19, 2005 I do not mean to insult but guessing from your post, you may not be overly experienced with this. So, maybe start back a bit further. You should have a tubeless tire in the back, look at the valve stem, is it bolted in? Look at www.rypusa.com for the tech manuals and look at the pictures of changing a rear tire, does your stem look like that? What I do too find leaks on tires, whether it is a mower, trailer, truck or bike, is I have a spray bottle that has soap and water mixture in it. I think you guys call it Fairy liguid, we would call it Dawn, or Joy. The soap that is used to wash your dishes in the sink. Anyway, a good squirt of that in about a one quart or liter spray bottle and spray it all over your rear wheel wherever it could possibly leak, valve stem, bead area, spokes, tread, sidewalls. Pay particular attention to any area's that may have been repaired in the past (dog turds) Let this solution sit for a while and it will blow little bubbles and make a little white "cloud" where your leak is. Then, depending upon what is leaking, and if you are tubed or tubeless will determine your next course of action. Quote Link to comment Share on other sites More sharing options...
jools Posted September 19, 2005 Report Share Posted September 19, 2005 Gas Gas are notorious for air to leek through the spokes as perce said. Tighten your spokes up, or their is a strong possibility that 1 may have snapped. some people put tubes in tubeless tyres, and if you pump it up, it can be quite obvious if your not sure because it rounds off the profile. other than that check for flat spots in the rim etc that could disturb the bead.

alan bechard Posted September 19, 2005 Report Share Posted September 19, 2005 Because I am just dying too know, and I have already been told I am incapable, just how does tightening up your spokes cause them too stop leaking.....????? Have you guys passing on this worldly advise actually done any of these? Or is this just a case of, my mind is made up, don't confuse me with facts?

trials lad Posted September 19, 2005 Report Share Posted September 19, 2005 Why are gas gas notorious for leaking spokes? they use the same rims as betas,shercos, and scorpas Btw why dont all the other bike makes use the same rim as the montesa's? as there miles better in the wasy that they dont need rim tapes and you can change a spoke without pulling the tyre off Quote Link to comment Share on other sites More sharing options...
