Since BMW have abandoned me after the warranty period expired and my pleading got me no where ......."We don't have any issues with the HP2 forks sir", "Then why have you happily replaced mine 4 times if there's no problem?" etc......I've had to dive in and try and sort them myself.
Even though I noticed play after only 1500 miles it's been over 10,000 miles since my forks were replaced, and the steering was getting somewhat erratic
to say the least.
As I wasn't sure of the extent of the wear (legs and sliders or just the bushes?) I just bought one set of bushes and seal and decided to try on the loosest fork - the RHS.
I managed the job with no special tools, and found no visible wear to the forks, and replacing the bushes has taken up all the slack (yet to test ride though
). A surprisingly simple cure.
Only took a couple of hours to do, and slowed by the fact that filling new oil is a seperate operation, the fork being rebuilt and put back on the bike (to tighten up the lower drain bolt thingy) before being taken off again to refill.
BTW the old oil was in a very poor state - very dirty, with signs of water ingress
I think I'll be looking at a 6000 mile change interval from now on.
Altogether a very productive afternoons work.
I'll have to do the LHS now

There's a suspension specialist near me who tunes SM race bikes. He stripped the forks completely, got the legs rechromed, rather than the fancier and weaker coating they come with and replaced the seals etc. This cost £400... They now feel a lot better than originals.
