    What squish clearance would be optimum with unleaded fuel?
    Just checked mine and it is 0.95mm - 1.05mm or around 0.039",seems big to me,but I am used to running Avgas.

    Hi Adrian , thats about right with a stock head volume. I run VHM heads with a lower squish of .75 but a larger volume head of 11.8cc. You will be fine. If you want to run avgas speak to Chris Barrat as he converted his 125 with a head from Ian Emberton for the MGP last year.
