I have searched and been unable to find a source for a black straight metal valve stem. (that is in stock)
Many sources for offset stems.

Any suggestions appreciated.
Thx
-Steve
 
I very much appreciate the quick reply.
Plse school me. Your suggestions, and all the others I found that match my criteria on Amazon are marked for automotive use, not motorcycle. I presume the mounting hole is a different size ?
-Steve
I think cars and most motorcycles have a 11.5 mm hole, but you should verify...
Some motorcycles have an 8.3 mm hole.

As far as I know, an automotive stem should work. (I'm sure someone will correct me if I am wrong.)
 
The oft quoted size for FJR is 11.3mm mounting hole.

Hoping for confirmation that an automotive 11.5mm stem will work.

I would be surprised if 0.2mm (1.7%) would matter (I doubt there is that much precision in the manufacture). Worst case scenario is to SLIGHTLY ream out the hole in the rim.
 
I DEFINITELY prefer an angled (90 degree) because any air chuck will work. The long straight hose ends at some gas stations are nearly, if not completely, impossible to use... discs get in the way on the front and the large hub and pipes on the rear.
And I point the stem straight to the side AND to the side of your dominate hand. I'm a righty so I put the rear pointing toward the disc side (so it's easy when you are behind the bike) and the front stem points toward the gear shift side (so I use my right hand when in front of the bike facing toward the rear). Call me crazy, but EVERY bike I have done this on a side job, and every time a friend would check my own pressures, the customer says, "OMG, I can't belief how much better and easier that is". Every Single One. Worth a try IMHO.
I use this type: https://www.ebay.com/itm/125355993727?itmmeta=01HW5KJC3ZMR08XRP2HGHHYYT5&hash=item1d2fccaa7f:g:hXYAAOSwTEdinsDR&itmprp=enc:AQAJAAAA8EFb76ahsiEBDbC5jJ3cJGmQq2DVjTPpxtrZa53dyKYux9u/rwy2JvS9n6sQ8LBLxFnqmhvSTeNrRpr6iD7ZOkAbVv2CBmHw0XCgzZvVv6FwzkR7jk3ArGTM++S2qk00wc+/vfYFnYsWx945YW+JlryLbwdZ/EwQ8NiouVlYdzRlbkTGd2f9HYck94rERmXJ1giE59abMs9RIxg0l+z4Vr3nh2wuwOuV6nrC4+JGxsRxVqLyoy7Pe40XTPG+92trosXpl7+QFF3lPo2BdF3OoC8Nhsi5q/s5A2NBSWp0/fUaJL1o7cJXKqNQYeWCPn25IA==|tkp:Bk9SR4jCybPhYw
NOT these because you don't need the length (and the leverage of them with a side force puts too much side pressure on the sealing surface: https://www.ebay.com/itm/112041570329?itmmeta=01HW5KJC3Z0SJNXS5ND1GXN5BZ&hash=item1a1632b019:g:UfEAAOSwMmBVn-yK&itmprp=enc:AQAJAAAA0ADodnhQZToW+Ki6ZA0jlXqqRxQibuDhxapy9xn0IicmGXjl+8p62gFlhigDdB84GtGRAxreENlWTE1udlTGGkPTFF9O3swHSHuUPvBqI1XBWcfYHNRq3/g53tbpuA0k3PAP/qfHlv5JPgTSaRYquCcvuZbnje8lzzXdU5drZh07+5f0vRxqx59dCnAQHlq+LYG9MCy6bFNXheZ5jva9by3mVTRnXCVJMR0IwidFJ1ivF7an36Y0oLdWTaeoXEQzd6jihlcDgmD1BiJGuuGdIM8=|tkp:BlBMUIjCybPhYw

Just to close the circle, this valve stem fits just fine.

90 degree stems are certainly useful, but not with (at least my) external TPMS sensors (frt wheel).
-Steve
These ones should work. Have the 90° for air fill and the placement of the TPMS sensor (on the end) won't put undue pressure on the seal causing a leak. (Don't look as good as the ones you bought, though.)

Nor are they black. . . . . .

-Steve
I have not seen those T-valves in anything other than chrome or nickel plated material. I suppose one could use a little black enamel on them if you really wanted to be able to adjust pressures without removing the sensors. (I like the look of the short black ones better anyway.)
 
Try CYCLEMAX.com They sell mainly to big Goldwing owners, but I bought several of these for a decent price. I think they also have angled and straight stems too.

I am looking to put TPMS on my 2011. I found an inexpensive receiver that hooks up to the bike (so no batteries) and has a voltmeter and USB outlet as a bonus (may be total crap, but worth a try for around $30 CAD).

If I want to use the stem-mounted sensors, it would probably be a good idea to ditch my right-angle stems in case the extra weight of the sensors induces a leak. I don't especially care for the look of the T-valve stems although they are practical. Thinking about the shorty stems (in silver) similar to the ones linked by @sapest . Found some on Amazon - very inexpensive...

I plan on going this route in the near future. Internal TPMS sensors with the 89 degree valve stems like I have on every one of my bikes. Only minor downside is only silver so I will paint them black myself.

I don't doubt that the internal sensors are better - especially if you are relying on temperature readings. The external sensors are easier for tire changes and easier to replace the batteries if needed but straight stems are recommended because the sensor weight can make for too much uneven pressure on the seal causing leaks. (Besides, I like the idea of the unit I linked having the TPMS, a voltmeter and a USB charger. Also no batteries in the head unit to replace.) Might be utter crap, but only one way to find out. The T valve stems are convenient for adding air without removing the sensors but I am not a big fan of the appearance.

Ok, if you insist (Admin, maybe split this off?)
Make your life much easier living with external TPMS sensors.
I bought a set of thin metric wrenches and cut them in half to use with the sensor jam nut, particularly the pain-in-butt frt one. The battery powered inflator turns another painful process into much less work.
