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.

... good luck on selling the bike mate ... although why you would want to part with it is beyond me ... i almost cried when i had to give up my ZXR.
