Thanks Bruce, some good info there.

I was looking for some combustion chamber compression figures from some people who may have tested there Victas before.

I tested my 125cc and found a figure of 62psi and my power torque was 75psi, and I agree a new set of rings etc may be needed, just trying to get a ball park figure before I go pulling it down.
