I have one in my saddlebag, it's still a pain in the ***. There is no easy way to get a chuck on the valve without removing the saddlebag and rolling the bike around to get the valve in the right spot.

There is no great solution that I am aware of. Just take the bag off and get down on the ground and do it - it's not that hard. Personally I think the extension is harder to screw on vs simply adding air. And the 90 degree stems scare the **** out of me because the centrifugal force imposed on that is huge. Even if it's metal, the grommet holding it in is rubber. I always use the shortest stem possible.

Guessing , yes or no on this one would be just as bad as an oil thread or the best place to put your gas cap while filling .

Thanks for your thoughts on the 90's . I forgot to have them put on when I had my tires done , bought one to put on at the next tire change , but you sure got me second guessing here . The 28 spoke rim is a pita , but I'd rather not worry about it and deal with extra effort it takes .

On the physics of it, the centrifugal force may be high, but the moment arm from the rim connection center line to the tip of the 90deg would be very small.
So, worth the risk or not???
Maybe I won't and just stay the course as I have for years...
Thanks Nevada for the input...

Interesting thought on the 90deg... I had pondered going to those at future tire change... Hhmmm

My Harley dealer installed a short 45 degree valve stem on my rear. Works great, but I still need to get on the ground to check air. Not sure what this has to do with the speedo issue the OP is complaining about.
PS.. lots of other vehicles have bend stems and seem to make it down the highway just fine.

Angled stems are a killer I tell ya.
