I put a right angle one on, and it got smacked by the cvt body, and so, it can't be 90 degrees out like shown in the pic, but 45 degrees only, which puts it up close to a spoke, so causing issues, as I had to bend it at a crazy angle to get the air pipe adapter on, and splitting the rubber valve resulted, so I removed them again.
Just my experience on my xc500.
