Ahhhh I see I missed the Fork type under your title, doh!!!

100miles,    switch to plan B.

Go to halfords get a Valve Stem removal tool ( £4 area + some 7.5wt fork oil )

Let the air out then remove the valve core.

Add 5ml's of oil to lube the seal inside,  oil stays at the bottom to help keep the seal air tight to.

Put Valve Core back in.

Put air in forks   and go see if that makes it plusher,   I'm VERY sure this will improve your performance no end and no way they can see the valve's been played with.

Before you send it back if still required later,  just invert the bike with air in the fork,  wait 2mins for the oil to settle then open the valve this will push the new oil out so it looks totally un messed with

You can use normal fork oil to,  but thicker would be better,  expect to have to top up the fork oil every few months,  15wt would be better than 7.5.

You can order the Fox Float Fluid at the tftuned site a little tube of it would do,  be here for the weekend to be sure and all.

Can you put a link for him to some Klunk

Need to sort some float / RS Red Rum myself for my RS's feeling like they need topping up again,  which means the lowers are slowly filling up with oil also!!

Its a good plan,  should be cheap,  might pick some up shortly to sort the Reba's out,  thanks.

My RS Reba Air Side lower Circlip popped off mid ride,  did I :-

a)  walk home and put them in the post.

b)  get the small adjustable spanned out,  drop the lowers off mid trail and night and refit the circlip using 2 small allen keys as a circlip tool.

Hmmmm I wonder

9months on, still fine!!

They were yours to gamble with & you do have a degree of mechanical knowledge (what with dismantling everything you own to see if you can make it work better) - I'm guessing the OP is not that confident.

Why risk turning a small incident into a £500 fcuk up when it can be professionally sorted for free? It may be there is a known issue with the new Floats (like the old 'sticking down' RP3 problem) which will be resolved at the same time. 

Upon reading the line under the title that I missed,    I too agree and said send them back,  personally I'm too lazy to send them back and didn't want to walk home and yes I like taking things to bits

I had and couldn't solve the RP3 sticking issue   and BOY did I try   if I ever have another i will be replacing the seals with UK Spec seals before I ride it in cold conditions for sure.

I was tempted to screw my own valve into the negative chamber so I could bleed it when it happened,  but decided not to,  despite hating that crappy RP3

mojo sorted all and now the forks are silky smooth, just back from edale. They said that the cap shouldn't have popped out and so a seal must have been faulty. alls well that ends well! Still managed to snap a chain on rushup edge tho lol
