    Hi friends.
    Would anyone be able to tell me what should the compression
    ratio be on the new chines 80cc motor ?
    With Thanks. Vlad.

    The compression ratio is very low, on the order of 6:1.

    a little higher if you have a slant head engine

    Thanks friends for information on compression ratio but I'd like to ask little more on
    the subject.
    I'd imagine, once the motor starts loosing power, one will have to replace piston rings
    but I'd like to know the ratio in numbers, how low can compression go down before one
    have to replace rings ?
    Also " Skyliner70cc " pardon the ignorance but I'm not following the expression about
    " slant head engine " as all motors - chines 2 strokes - are in the slant when mounted
    but I'd appreciate if you'd explain what you mean by " slant head ".
    Thanks again. Vlad.

    some heads have the sparkplug at an angle...they are called 'slant-head'
