My Reba forks aren't fully locking out with the Poploc. I suspect that the oil levels my be low or miss matched in the fork legs. I checked out the Sram video on You Tube and saw they used a big syringe to inject the correct volume of oil.
Whereabouts can I fing such a syringe? Where is the best place (cheapest) to get fork oil. I have three sets of similar forks, so I might as well try and service the others too.

it is worth buying good oil imo. cheap oils don't have the anti foaming agents in. silkolene fork oil is well regarded.
syringe off ebay
Would a motor factors stock silkolene oil?
If you email me your address then I will post a couple of syringes out for just the postage cost.
I accidently bought a box of them from Ebay last year (Sterile Turemo 50ml ones....a hundred of the buggers!).
Keep meaning to buy some silicone tubing and sell them as brake bleeding kits!
local vet will sell you a syringe
A motor factors will probably have fork oil- a motorcycle shop will have.

Thanks for the help on this folks.
I've recently serviced my Reba's and after much research I used Redline Lightweight in the damper and Mobil 1 0W-40W fully synthetic in the lowers of both legs and the top of the air side. A thicker oil is recommended for the top of the air side such as gear oil, Float Fluid or Redrum but all is fine with mine. I also replaced the o-rings with the £8.75 kit off ebay and got syringes from ebay.

I use rock oil off crc for £8, 500ml. A motorcycle shop may stock rock oil, as I got 1l for £7. Silkolene is over expensive and not as good as it used to be.
Mrs_oab gets a supply of 50 each quarter from the NHS, so far her pleads to stop giving her so many are unheeded, so I have plentiful supply - I was wondering if to head over to ebay with them....
I'd say Nealy has it covered right there! And a big PLUS to that evilhomersimpson on ebay with the o-ring kit: works for most RS forks I have and is a real nice guy to deal with / answer questions.
Only thing I'll add is dont try and use anything apart from shock oil in the damper(if you have to top up/ change it). Normal oil turns to mayonaise. I just use what CRC have at the appropriate weight. Works perfect.
And I've never used engine oil in the lowers - but I cant see why not.

Definitely only use suspension fluid in the damper or open bath forks. Also you can pretty much disregard the stated oil weight on the bottle as different brands of the same stated weight will be different viscosities. Rockshox 5W oil is 16.1 cSt @40C so you want something close to that, Redline is very good stuff and their Lightweight is 18.4 cSt @40C so that's close enough for me but you can mix fluids to get a specific viscosity. See here for loads of info http://www.peterverdone.com/wiki/index.php?title=Suspension_Fluid
The oil in the lowers of a semi-bath/sealed damper fork is only for lubrication so you don't [i]have[/i] to use suspension fluid. See page 14 of this PDF ( http://www.enduroforkseals.com/sitebuildercontent/sitebuilderfiles/pike_dual_air3.pdf) which recommends fully synthetic motor oil in the lowers. Also here are a couple other of threads discussing using engine oil ( http://forums.mtbr.com/shocks-suspension/mobil-1-5w-30-correct-715257.html & http://forums.mtbr.com/shocks-suspension/better-clinging-oil-than-foxs-red-green-oil-701950.html) and why it is better than suspension fluid for lubrication, basically it's slippier and clings to parts better.
I've got a pair of '08 Reba 29er 80mm travel forks that have started bottoming out with a clunk about 30mm down into their travel.
Does this sound like it might be put right by a standard DIY service along the lines of [url= http://www.bikeradar.com/gear/article/workshop-how-to-service-rockshox-reba-suspension-forks-23142/ ]this bike radar service guide from google?[/url]
Also, it seems to suggest only one type of oil, rock shox redrum/pitstop, is needed. Yet all the chat on here is about 5w and 15 oil as well. Am I missing something blindingly obvious or will the redrum/pitstop stuff suffice?
I doubt that service (lower leg only) will sort out your problem as I think you'll need service the damper and air piston too which are inside the stanchions. This requires circlip pliers and a 24mm socket plus the O-Ring kit but is pretty easy.
Redrum/pitstop oil is fine for the lowers as is any 15W fork oil or good quality synthetic engine oil (not extended life) because it is only for lubrication. The 5W suspension oil is for inside the damper in the right leg stanchion.
OK I am now in the miserable throes of a DIY fork service following [url=http://] http://www.sram.com/sites/default/files/techdocs/tm_my08_e1.pdf [/url]
I am at step five, covered in escaped oil, and the air (left) side fork is resisting all manner of taps with mallets and removal with fingers so I can't get the lowers off. Any suggestions?
Have you unscrewed the bolts enough?
Give the shaft a proper whack but cover it with a block of wood or use a soft mallet. If the shaft is already pushed flush with the bottom of the lowers then hold the crown and pull down sharply with the fork brace
OK, got past this bit, hadn't loosened the bolt enough. 😳
Latest ballsup is when trying to service the damper, removed circlip and the kinetic energy in it saw it shoot off the pliers, ping off the wall and disappear somewhere in the room.
An hour of turning the room upside down and it's still MIA.
Are circlips generic things or is the one that was in my forks likely to be some special rock shox only circlip?
I'm fairly certain it'll be a standard size although don't know what it is.
OK, so I finished the service of my Rebas after a bit of trial and error, described above.
I followed the rock shox tech document instructions [url= http://www.sram.com/sites/default/files/techdocs/tm_my102.pdf?bcsi_scan_FC8B19B84F4BB9EE=intMOu/bpEBsdHGazW6Y5rv8y9tYAAAAlkQ6FA==:1 ]Here[/url]
I replaced the all the O rings, foam rings and topped up the oil with the recommended weights and volumes, and pumped up the air chambers to the recommended weight.
Having put the forks back together again, the original fault appears to be fixed - there is no horrible clunking, bottoming-out noise, and I'm definitely getting more travel. I'm still not getting 80mm - there is now only about 65mm of stanchion showing above the tops of the lowers, and going by the O ring I put on the stanchion I'm only getting about 55-60mm of travel out of the 80mm I'd expect.
Any ideas as to what I've done wrong and how to put it right if have to open 'em up again?
