Not on my AK. But I did put 83 deg stems on my CTX1300 and 90 deg stems on my 2013 Burgman 650.
The issue putting them on the AK is that you will loose the factory TPMS. The tire pressure sensor/sender is part of the valve stem on the inside of the rim. Attached to the metal stems that are OEM.
Take those off and you loose the display on the dash for tire pressure.
You can add an aftermarket system but that would be a separate indicator. Those are best mounted using a metal T stem that has a straight up valve for the TPMS sensor and a right angle valve to add/remove pressure. I know a lot of riders who do that on other bikes... just not on the AK.
For my AK I have a 1/4 inch NTP air chuck with a quick disconnect fitting for my compressor at home like is used at many tire shops. The NTP air chuck is more versatile than the wand air chuck I also have and I use it more often on everything.
When I go traveling I carry a mini air compressor anyway that has a 90 deg chuck on the hose so never need to stop where the hoses might not be easy to work with.
For some air hoses at gas stations and other places while on the road there are right angle adapters that be TEMPORARILY put on the stock straight valve stem just for adding air... but don't leave those attached to avoid stress on the stem.
