    I need raised top pistons, the 250 combustion chambers are rather large.

    They look to be similar to the cb125T widths?
    in my defense Rootes blowers make power at low revs anyway.

    F5, that's rubbish. Get your facts right. They suggest only 5900 rpm...

    I have a stack of FZR bits. Let me know if you want anything. Is there a possibility of running a cut down FZR head? I have 2 heads with various damage, and cams etc. How many revs will the bottom end handle?

    i think original one was one piece but there are aftemaeket three piece.?
    i think std sleeves they can fit 400 pistons it might still smoke but it will go better...

    Thankyou, I have a half head here but rules call for air cooled, unfortunately. Good thing is E85 is not banned.
