    VXR/S stock compression.

    Hi greenhulkersCan anyone tell me what the stock compression (psi) is on their machines? I realise all results will vary slightly. Just after a ball park reading. Not after what's in the service manual.It's to assist with benchmarking.

    Yeah, mines all good. I just never had the opportunity to take a stock compression reading before the mods.

    They all differ slightly but I would expect 140ish...any other readings guys? Ill just average them.
