Has anyone used these valve stems? Thinking it would be a great way to upgrade to metal stems before adding FOBO or the like without dismounting the tire.
what keeps a standard valve stem in the rim? a couple notches in a rubber stem.
I've never seen those before but looks interesting.
I like 90 degree valve stems and still looking for a good INTERNAL tpms system that's not hooked up to a phone.
Compression fittings. I have no issues running valve cap style tpms on normal short rubber stems. How many people ran dice valve caps on long rubber stems as kids. Never heard of a failure and the tpms caps are not measurably heavier than the metal caps that come with balance beads kits.
Just one data point, I did have a rubber stem crack with the TPMS sensor on it on my '06. Lost front tire pressure on the highway. Luckily got pulled over before it was completely flat (TPMS warning was helpful). Since then, I've always used metal stems. My '16 has the metal T-stems with FOBO as installed by the previous owner. YRMV.
I had FOBO on straight stems for a while. Giant PITA! I can't imagine putting them on short or extra short ones. From my experience- do yourself a favor and get some Hawks Head Tee valves. They make dealing with the FOBO so much easier.
IMHO still a PITA. I prefer not removing the sensors at all. The added benefit is using the FOBO to show me the air pressure when airing up rather than using a separate pressure gauge.
To each his/her/its own, I'm not trying to convince anyone of anything.
I always use t valves. When I switched my (superb) Fobo over to my 2018 bike,
I ran the sensors on the rubber stems. They already had a noticeable lean after a few hundred miles. Rubber + sensors = no bueno.
I have not tried the Colby Valve Stems, but I see that Amazon sells them. Colby has no retailers in my state.
The big question for me is "Do they fit in my rims?" What size are the valve stem holes in the FJR rims?
Colby has an Emergency version (no tools) that could save the day if a regular valve stem fails in any way. I can see adding a set to the tool kit, even if it just "saves" another rider one day.
A buddy of mine lost a tire on his Goldwing because he installed FOBOs on rubber stems and the stem broke. The caveat is that he didn't use new stems.
I've tried to use the FOBO to set tire pressure but the refresh rate is too slow. It's much easier to use a pressure gauge.
I installed my sensors on T valves. Really works well.
The compression ones might be OK but that makes me nervous..... T-stems for me. Aluminum 83 degree OK also. Straight stems, no.
Story time... when I was in the auto biz, the workers would steal the aluminum caps off the (internal) TPMS sensors, then put them on their car for a little bling. After a while, if you needed to add some air to your tires, oops, they wouldn't come off..... brass and aluminum hate each other, lol. Anyway, my job was to get extra caps from the TPMS supplier........
Roger that
I'd love these *90 deg in American stainless or Yamaha quality aluminum.
My short straight rubber vucanized to brass stem, delaminated a year ago. Thankfully it happened in the driveway while doing my preflight inspection and tire pressure check. the whole brass core slipped right out of the rubber nipple... no riding that week.
Perhaps God was telling me to get a new nosewheel.
