    pk 100 or is it?

    Post by MH 13 on Mon Jun 25, 2012 8:58 am

    right i came to replace these piston rings on the pk100 today, took the barrell off and cleaned the piston up to find it marked '49',

    then the piston rings i had to replace them with were bigger than the ones i took off, so am i right in thinking this is not a 100 and actually a 50cc?

    im guessing iv got 57mm rings instead of 55mm, can anyone shed some light on this?

    they sound like pk125 piston rings you have there , so that could be a pk 125 piston you have or a 50 , check what is stamped on the main cyclinder m8

    I think youve been sent the wrong rings dude

    55mm is standard 125cc
    57mm is 130cc

    Yours should be 49.5mm - 50mm

    Get some vernier calipers on the bore and piston mate
