tube or tubeless tyres for 1980 Suzuki's?

[Baatfam]

I found the same or very nearly the same valves on Amazon that Bob posted above from NAPA. I'm probably overthinking all of it, like I usually do. But I do not want to drill the hole larger. We'll see how it goes.

You shouldn't have to, if you get the one Brian suggested, with a 5/16" pilot. (Or 8mm)
Stock, the hole in mine was slightly larger than 8mm, so the one I bought with a 9mm pilot worked.
Note: I didn't drill it larger, I just let the 9mm pilot clearance the hole a bit.

The measurement of the flat area I took may be a little off (14.5mm. needs to be 16mm). I'll wait until I have the new valve and see if the rubber fits in the recess before doing anything more drastic.

If you find the NAPA one, I can verify it will work...

Wont have that in uk but anyway all I/we need is a m8*16mm
counterbore bit IF my rim needs it to fit a tubeless tyre.
As for valves they have plenty in tyre places
as would only do it in an emergency [unless
as some say it is possible ...]

Getting the tyre off I might give it a go as I
need a new tyre right now.
I have asked this question before on another thread years ago
and discovered the levers to carry with on
long adventures. never bought em or used em mind.
I'll have to find that thread and the levers type


the bottom line is I would prob use that aerosol
gunge to fix tube or tubeless tyres if in peril
on the spanish deserts ...... and get to a town.
As I rode through the plains or spain in the rain
i thought if i get a puncture I'm screwed.

I attach pic of one of my break downs in 2016,
some of you may remember. this was in amsterdam
and with the assistance of this forum in real time
managed to get going again in 7days....
7 days in amsterdam . what a place to break down !

Thanks Bob, looks just like this one I ordered from Amazon. If it's not, I'll hit up NAPA.

I notice you don't get a lock nut with the Amazon one...

Looks like you're right. I can just pick up another nut same size as other, right? nothing special about it?

Funny, the more I try to do as much of this from home as possible, the more likely I seem to be to have to go to some store anyway. The good hardware store with the good loose hardware selection in my town is in the same plaza as NAPA.

The nut on the old tube should/might be the same.

Brilliant.

Funnily enough, the picture with on the NAPA site for valve 90-426 is the same picture used on the Amazon listing I bought, showing only one nut. Will see what comes from Amazon - (tomorrow, maybe?)

Hmmm....Indeed it does. Ha....The one I measured came from a sealed package. (When I bought mine local, they only had two, so I bought them both.)

 

[ukjules]

Who cares about valves..... ?
I despair.

Back to the Yamaha site.

 

[Rich82GS750TZ]

Jules,
I apologize if I've hijacked your thread with my own issue, but it is all related to your initial post, I think. And I believe a lot of good info has been presented here that will hopefully help some in the future.

Best.

Got my tire remounted today onto my freshly de-corroded wheel. The valve I bought fit perfectly, only came with one nut, so I used the one from the old tube for a lock nut. The tire installation was more difficult than I thought it would be. I had the tire’s beads squeezed all around with giant zip ties as suggested by some videos. I think this actually hurt me rather than helped. As toward the end (of me swearing and sweating with the tire 3/4 of the way on), only after the last two zip ties broke, allowing one bead, then the other to slip over the rim, was I able to finally get it on. Maybe the zip tie thing works for some tires/wheels. Didn’t work for me. Found a set of 3 rim protectors and a Gallon of lube on Amazon for cheap, worth every penny. I also could not have gotten this done without the 24” tire iron I picked up at HF to supplement the 2-10” irons I already had.

Anyway, it’s on. I did not get the satisfying pops of the beads seating on filling with air. Even filled it to 7O psi. Then reinstalled the valve in the stem and settle it to about 50. I’ll check in another hour before mounting back on the bike, then reset to running psi. Just to check, wiping the bead area with more lube yielded no bubbles, so that’s good. If no pops, are the beads really seated? I did use an actual tire lube/bead sealer.

 

[Baatfam]

Nice! Good to see....

 

[bwringer]

No, the beads don't usually "pop" when the bead seats on conversions. They just sort of ooze into place.

Weird about the number of nuts -- the Napa valve stems in my stash with the same part number look identical, but they have two nuts plus that domed washer. I just installed a couple a few weeks ago.I used a thin wrench to hold one and torque the other a bit, and applied a drop of Loctite green (low strength wicking) thread locker for that cozy belt and suspenders feeling.

 

[ukjules]

It seems I need some humble pie .... as only now in my
dumb a%s ignorance do I realise I need to
make this conversion happen and by a valve .....

So its tyre off.
check rim. (read this thread)
drill rim with one of those drill bits
buy one of them valves
and new tubeless tyre .....

 

[ukjules]

A nice pie that was.

Front wheel off asap (by dealer )for new tubeless avon road rider.
I need to convert rim !!!!!!!

1) remove tyre and take pic of rim (for my own benefit but will post)
2) need m8*16mm counterbore drill bit to convert valve hole.
q) this I assume to expand original hole and make nice
flat area for valve seat to not leak.

q) I am in uk. can any expert with time on his hands
find the drill bit on ebay or amazon - as can get that next day ?
I cant quite get which one to use ?

q) when got the drill bit it is just a simple matter
of drilling out hole a bit (to 8/8.35mm) and making a flat area on
inside of rim (16mm ish)

A 1/4 slice of the humble pie to anyone ....... who can help.

 

[ukjules]

is this the sort of thing ?

https://www.ebay.co.uk/itm/HSS-End-...-/393045537610?_trksid=p2349624.m46890.l49292
but only has 13.4mm flat area when drilled?

 

[ukjules]

The only one I have found is
https://www.ebay.co.uk/itm/M8-x-15m...SelectionMarkerStart~!!~OMSelectionMarkerEnd~

someone said on here this is fine bar not being
16mm (it is 15mm) .
surely the valve will fit ok on 15mm ?

looking at one of my wheels I seem to have a
tubeless valve on a wheel, which hasnt been
coutberbored modified.

 

[ukjules]

Arghhh I'll stick a tube in it as it is meant to be.
Too much hassle p^%$&ng about.

My only concern was due to the massive
rides I do around europe ..... if I didnt
do this I would even think of this as a question
worth asking.

I'll carry tube sealant spray and
rely on the AA (break down people).

avon road rider with tube it is.
