    gpr advice

    hey guys first post, although ive been using greenhulk for how-to info for a long time, now i have a real problem i need some sound advice on ,and here goes, i have 2001 gpr i ride recreational but lets face it who doesent like to go fast, anyways last spring i droped a powervalve on no 1 cyl i had the powervalve repaired and went on my way about 10 hrs ride time later i lose all compression in no 1, pulled it apart and i burned a hole thru the top and side of the piston apperantly from heat caused by deep scratches on the cyl and piston, ihave since sent cyl to millinem tech for a redo and now the comes the question do i just rebuild this cyl or do i rebuild all 3? compression when powervalve broke was 105,110,105 but the other 2 cyls look good still...thanks

    carb rebuild
    cat removal/ d plate
    new top end depending on hours
