Developed a slow leak from just one rear spoke on my two year old KTM 890 Adventure. The gasket looks perfect. However, I suspect slight separation at the air valve grommet on the tubules bladder. Really impossible to detect cause of leak. Was yours a catastrophic failure of the bladder at the grommet ( valve stem )? Any idea what cause separation of the metal grommet from gasket? So I am going with Outex tubeless system. Thanks for sharing.
I lost air rapidly out on the trail, and the tire went off the bead and ripped the tire gasket. So it’s really hard to tell what happened. I have 50,000 kms on that gasket so it was probably due. I’ll check out Outex! Thanks for watching.
As you know that KTM tubules gasket is tight as a drum skin and takes a gorilla to pry the beaded edges out of that groove. Moreover, the air valve is independent of tire. I am inclined to believe the rubber gasket bladder failed first. If you don't mind, I'd like to post this on one of the KTM 790 Adv. wheel and tire thread to share.@@adventurod
