The boy had a puncture. Slow leak from "nail" in new back tyre on Kisbee 50cc scooter.

He's gone and put some sort of tyre sealant in nit.

I have not repaired a tyre that's had any sort of this stuff in before.

Is it possible to repair after the application of goo? What should I expect when taking the tyre off?

Some goo.
I don't think it's particularly difficult to clean off, it's just messy and not something a tyre shop would want all over the floor.

Take nail out and leave stuff in. There is that small risk of it going flat but I have run a tyre with sealant in it to a bald finish. depends how big a puncture really but I swear by the stuff.

If you go to a shop they will tell you,
"Aw we canny get oor patches tae stick tae the inside o' the tire eftir ye pit sealint in tae it."

If it was Ultraseal then pull the nail out and ride on.

The tire should be OK. So long as it is a clean wound.
There 'could' be 'difficulties' if there are a lot of cords damaged. I don't know if there will be a steel belt in the tire but the wires of the steel belt 'can' keep the wound from healing properly.

But so long as the 'correct' prescribed amount of sealant for the tire size was injected the tire should be fine.

It is important that the correct amount was used or the tire cannot balance the sealant.

Ultraseal is manufactured for hi-speed use so that is one of the benefits.

I use it, no problems.

It is worth mentioning to tire people when you get new tires fitted. Embarassed

Dumb questioon, but on a moped, would it actually have a tubless tyre?
Plenty of lightweight 125's still have tubes.

Yes, it's a tubeless tyre. I fitted it about a month ago (just before the main bearing issue.... Sad ). It's probably done about 150 miles....

Pull it off, stick a tube in?
Only going to do 3o mph.....
Probably cheaper than a can of cloopyshit

I was thinking of cleaning it (or rather thinking of getting him to clean it) and then mending the puncture, since it's a decent tyre (Heidenau K58). To put a tube in is difficult due to the rim's shallow well, and the absence of valve hole.

I'm told the goo is "tyreweld", which according to a search "washes out of tyres easily after use", and is intended as a temporary fix.

Tireweld is a temporary fix to get you out of trouble. It will have to be repaired.
It is water soluble.
Nasty stuff.
If you can do he can do himself it's less embarrassing than arguing with tire people.
It is a bit of a cnut to was out. It's soluble but messy.

OK thanks. He'll be around tomorrow. I'll write up what happens....

He's got some "mushrooms" from a car boot sale, but no glue. Self-adhesive? Rubber solution? Evo-stik? Chewing gum? What's the glue for these things if they'er not self-adhesive?

New tyre is £37 delivered.

However, don't worry about goo. Deflate, remove, wash under tap and dry. Repair if you think it's worth the effort.

No I'm not "trolling". I've never used tyre mushrooms, and I (still) don't know what they're stuck on with. I'm assuming it's not ordinary rubber cement as used on inner tubes (but that'sas vague as your "tire" repair adhesive.

A brand name would be nice, then I can find out what the stuff is. Anyone?

Aww sorry for suggesting you were trolling. My bad Big Yin.

I didn't know your Google was broken.

PS I simply punched 'tire repair adhesive' into the search box.

It's OK. I went to the experts (National Tyres). They don't repair motorcycle tyres any more for a particular reason, but were good enough to show me the procedure and give me a tube of Rema "Tip Top" Special Cement BL (flammable).

It's defiitely not "rubber solution" as used tor patching inner tubes. It is a cold-vulcanising mixture of polymer compounds in a trichloroethylene solvent base.

N.T. also commented on tyre sealants. "Tyreweld" they are OK with, but "not OK" with sealants containing organic propellants.

If you care you could have a squint at the British Tire Manufacturers/Industry's guidelines on tire repairs.

If you are a worrier then you won't repair a bike tire. But I have repaired bike tires and not had any incidents.

I think one issue is being able to determine the extent of any damage.
Or more accurately, having the skill and knowledge to inspect and decide if damage is beyond repair and LOTS of damage is.
Primary cause of scrapping an injured tire is damage caused after the initial puncture when a tire is run flat and the fragile sidewall is crushed by the rim. The hammering effect of the road surface destroys the bonds between the tire construction layers.
Tires are complex machines.

But generally a nail hole can be plugged and forgotten if caught ASAP.

It depends, I have a couple of times (on a bike) after sudden deflations not far from home.
If it's well worn anyway changing it might be a good option.
It's not as impossible as you would think to go several miles, front or rear.

Depends on which Dictionary you use.....
I would have said side of the Atlantic but there's still a bit on the wrong side above the 42nd parallel that is rather confused.... When I was about 14, my Kanook step~ish bother, ended up writing his 'English' homework in Quebequese... which is even less like French than American is English... because he was fed up with the argument between his mother and his American 'English teacher' on this very word!?!!!!!!

We do in trials!!!!!! {occassionally} That's why we have bead clamps.
ISTR that Perelli tubless were the first to endorse a trials slick at atmospheric. If tubed, best to keep them over 2psi to stop them fretting,
