Mine just started leaking (a tiny bit TBH) on the spring side after a day at Laggan.
I have an ongoing issue with the 2-step air managing to transfer pressure from +ve side to -ve side where it gets trapped, which makes them drop down to shorter travel (134mm at the mo, on the long setting!)
Give TF Tuned a bell. Their technicians are all ‘wired for sound’, so they can answer calls and give out advice whilst still working on jobs – they are happy to advise.
I called them and they were very helpful. I’ll be ordering a U-Turn coil conversion kit soon, as advised by them.
