Ill be damned if i can find this anywhere else so, what is the 'normal' compression for a zxr250c that has done about 25000 kms? I was selling it and a buyer got a comp test done that said that it was about 95 psi across all four pots which i thought was getting fairly low and therfore the cam chain and/or sims need work. The bike shop on the other hand said that it was fairly normal. I have found that the compression ratio is suppose to be 12.2 so that x air pressure = around 180psi so please tell me to stop wasting my pennies and 95ish is ok.
