I was wonder has anyone try to use 90 degree extension on AK550 or any wheels?

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.

I forgot about the TPS. What do you think about 90 degree extension?

Got them on both my machines. Makes topping up the air sooo much easier!

You might be able to get away with using small 90 deg extensions on metal stems like on the AK. Still puts extra stress sideways on the stem but being metal stems they might not have issues for a very long time. If used on rubber stems you will have issues with the rubber breaking down due to the stress. Nothing ruins a ride like having a stem fail resulting in sudden loss of air in the tires. Still best to only use extensions while filling the tires and not while riding just in case. So definitely get a 90 deg extension that you can remove for riding and put on while filling the tires. Just my opinion/recommendation.
