Tubeless tyre valves?

[NTECUK]

If you don't want to muck about, do the tube idea.
All you have to remember is that you reduce the the ratting by the next group down.
Jobs a good un.

I thought you bought a project bike? One that also needed:

Exhaust painting.
Sidestand switch wires tidying.
Chain and sprockets (special 5 bolt pattern rear sprocket).
Rear hub.
Mirrors.
Air box.
Service.
Straight handlebars.
De-rusting.

Yeah, I've been and bought two inner tubes to use on the front, (for when I break the first)

One question though, on the valve stem on both inner tubes, there is a domed washer at the base then two nuts, the one I just took off had only a domed washer and a single nut.

The internet comes up with three main different approaches as to what they are for:

1-The domed washer only goes on the stem, the stem is passed through the wheel then either:
1A-one nut only is used to lightly to secure the stem in place, the other nut is spare
1B-one nut is used to lightly to secure the stem in place, the other but is used as a lock nut to keep either the other nut or the dust cap in place
2-The domed washer goes on the stem then one of the nuts is wound down over it to the bottom of the stem. The stem is then passed through the wheel then the other nut is used to secure the stem in place.


Any opinions?

I don't like you, anyway, shut up, you bought a Honda and can't even source a service kit

The tube domed washer. Pop the valve through rim, nut then 2 nd nut locking the first
The dome fits in the recess in the inside of the rim

Sorted.

Latest update in the saga:

So the rear tyre went on without an issue, and has been holding pressure for a few days now but the problem is with the front one, the tyre is a tubeless type, I was told I could run tubeless on these wheels so took a gamble, but now the tyre is off it seems more likely that the front is definitely a tubed type.

A few people and bike shop near me, that also sells these Chinese 125 motorbikes (and supported by several articles I have read) said to just run the front tyre with an inner tube even though it is a tubeless tyre.

It seems common census that you can do this as long as you downgrade the speed rating, or at least don't approach it, which it 93mph on this tyre... I have a feeling I'll be struggling to get 70mph so I am happy with this.

I got a couple of inner tubes, as I KNOW I'll end up pinching it if I only got the one. So I spent last night trying it out, but I just can't get the tyre to fit, there is about 1/4 of it that just does't seem to fit on to the bead, you can tell as the tyre wall isn't as high in that are as the rest of the tyre, at first I was thinking that maybe the tyre is just a little too small, but after several attempts, it is not always the same 1/4 of the tyre on both sides that won't seat, and also where the valve is the tyre is sitting a little too tall and you can see top of the bead.

At this point if you bend the tyre back you can see the edge of the inner tube so it looks like the inner tube is not completely in side the tyre at that point, but after lots of lubing and wrestling I got the inner tube within the tyre at the point and re inflated and it happens again. The tube is not twisted at any point, I have had my hand under one side of the tyre and had a good feel all around it and the tube is nice and smooth all around.

I might just give this one over to the garage that will be MOT'ing it, I've got the BlackBird booked in with him on Friday for the MOT also so will ask him then. I'm a bit gutted, I got the tubeless one on without any problems. All good experience too though. I'll be practicing with some spare wheels and old tyres I think.

And just for good measure, here are some pics I took of the rim last night (fnar fnar)

Try talc on the inside of the tyre as well as the tube.
Don't forget to only have the valve loosely located in the hole when inflating.
If you trap air between the tyre tube and rim. When you ride it that air can rapidly deflate and your on your arris

Cheers, I tried to have the valve as loose as poss when inflating but got to have it most of the way out or my adapter won't grip it and won't inflate it.

I need a new one anyway
