| Apeks regs are 02 compatible, and the standard service kit is used regardless of 02 state.
As mentioned the main diffrence is the grease used, some shops use 02 compatble for all some dont.
At 50% it is debatable whether they need to be reserviced, and comes down to how you feel about it.
Personally I service my apeks regs once every 4 years or so, with a new kit, and use 02 compatible on o2 fittings, silicaon on everything else. This is partly because I'm a cheapskate and partly because I have 6 regs, 8 cylinders and if I followed all the rules it would cost me a fortune. |
