    Question Best way to fix slow rear tyre leak

    Dropping around 5 psi overnight.
    Had a puncture repaired at motorcycle shop about 6 months ago. Middle of rear tyre on Suzuki Bandit been holding pressure fine since until a few days ago.

    Should I bite the bullet and take it back to the bike shop or would a tyre pando fix such a small leak on a tubeless tyre?

    Thoughts appreciated.

    I'd be taking it back and explaining what has happened.
    6 Months is a long time in a tyres life, kerbs, rocks, cagers and their cars, you know, could have been anything, may not even be a hole in the repaired place.
    Go on, go back there,give them the chance to check it out and make a good call.

    Don't screw around with your life. 5psi overnmeans a bigger problem.

    How old is the valve stem, is it an old valve core? I've had many issues over the years of old stems and valves being disturbed and not reseating later slow leaking.

    Of course a quick spritz with soapy water in a spray bottle should tell you if its bubbling around the repair, the base of the stem or the valve core. I've even had valves leak when the cap is screwed down tight, depressing the valve just slightly when the wheel spins. Old valve don't cost much to replace with new. Old stems can perish and crack and given the age of Bandits now do you remember last time the valve stems were replaced? Press it from side to side when spraying soapy water on it. Just a suggestion.

    At least with knowledge of what is happening and where, you can direct the tyre tech to the problem.

    Thanks for the replies and humour guys. I'll take it back to the bike shop and get them to check it out. Cheers

    Wheel spikes Repeatedly breaking sound barrier has same effect too. Sometimes they match reasonably frequency of valve stem and pulses it open.
    Usually you’ll see contrails forming in your rear view mirrors when this happens along with windows breaking in motorists cars in slow lane.

    Extremely rare, requires a mismatch of a long valve core not seated in tight enough and a rubber cap with a moulding nipple on the inside in just the wrong place.

    Its just one unusual item to tick off a process of elimination. I have had so many slow leaks on newly fitted tyres its infuriating, so now I insist on, and pay for new valve stems and valve cores any time they are disturbed. It raises eyebrows when I do ask for it to be done, but DILLIGAF, its my $ on the line. Slow leaks trash a tyre in no time. This is something I started doing when I was earning income as a bike courier (back when such a thing existed pre email and faxes) and time out of the day was money never to be recovered. I'd work through a set of tyres every six weeks or so.

    What a load of garbage!

    Everyone knows its the 5G radiation altering the temper of the spring in the valve core.

    You could get it looked at, but be prepared to buy a new tyre.

    With rubber snap in valve stems it is tyre industry best practice to replace them each time a tyre is fitted

    You'd think right?

    Should start a poll, new tyres or tyres removed for repairs, has it been returned with same valve stem in situ? Bet there is a better than 50/50 fail rate.
