Best way to fix slow rear tyre leak

[Kiwi Bandit]

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.

Buy some pair on special. 1200 responds to new tyre to be lively

Pandos are only ever a 'get you home' measure.

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.

I've never had a slow rear tyre. What's that like?

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

Jeepers! I'd never considered that.

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.

why? there's people out there who go through several tyres a year, there's many other rubber components on the bike that doesn't get the same treatment, like fork seals.
How much of this is because the valve is likely to be tired, how much is profit driven and how much of it is so you 'look like' you are being thorough?

I do my own tyres on my bikes, only replace the valve stem or valve itself if necessary. Haven't had a valve go bad in years, but have had the odd slow leak due to an object in the tyre itself.

As for tyre industry practice :sweatdrop

[F5 Dave]

On the missus car I've had a couple of valves that would leak alarmingly if deflected while checking pressure. That's certainly not ideal and were changed.

I don't disagree regards the other rubbers.

I do my tyres my way, not the tyre tech's way, coz its my $ and my neck on the line. If thats not agreeable to them, I just quietly move on to a workshop that wants my custom. Have been known to walk away and do it myself on a few occasions.

Not trying to tell anyone else what they should do but.

(edit: just thought I would say Palmerston North dealer workshops are very very good with tyre mounting without slow leaks. 100% success rate so far over 6 pairs purchased)

I think you'd lose, I doubt it's even be 1%, I see it every week working in the car tyre industry, rubber snap in valves are a wear item, on a motorcycle where the tyre mileages are way less than a car you would most likely be able to get away with every 3 or 4th tyre change but I'd replace them every time
