Uldis - your right - but its not just the trackdays now its getting back here to do them and as Mark pointed out I just bought new 48’s …
Anyhow - I calmed down and looked into it further - the adjuster (on one of the fronts ) loses its clicks, after you go fully hard - so actually what happens is the setting stays fully hard then regardless of the adjuster position.
( fully hard means very little “sping” in the piston )
Gently tapping the end of the shock with a rubber mallet brings the clicks back to life and the adjustment … so I guess the gas is OK its the adjuster that seizes … which explains why I thought the ride was “funny” - one side fully hard the other at 12 clicks
The other front one has similar characteristics - the adjuster is very stiff and you cant always feel a click.
So all 4 are off and replaced with aluminium struts and I’ll drop them at Nitons on my way back to the tunnel on Tuesday …
Mine have been fine, but have not done that many miles. They do make a big difference though, and I would still get them irrespective of Andy’s problem.
