    I sent my 121VR pistons and sleeves for resizing. I should receive them shortly.

    Anyone tried that kind of service?

    Are there any pros?
    Or is this just because it's worn?

    Rays is the best!

    But when I was racing Gas Truck I would just buy a new sleeve and piston (Dynamite 12Spd)

    i've got a gallon and a half on 1 b4 it went out (os speed mag head version)the other is nearing the 2 gallon mark and starting to feel like it starting to go, i already have 2 pinches on both motors so they are getting close to getting a fresh set of pistons and sleeves, ill do a complete rebuild piston and sleeves and conrods ill also check the ceramic bearings but will likely replace them for peace of mind .
