    Break in help and oil ?

    Guys I'm rebuilding my GPR and I will be using new cylinders that have been replated and new pistons.

    1st ? how should i break this baby in? (what oil and how long ect)?

    2nd ? I went to the Klotz web site and saw that there is a Benol (castor) oil which show virtualy now wear in the tech sheet. What oil is best for my ported motor? Klotz, Amsoil? ??? Yamalube 2R?

    Thank you
    Mike

    No need to run straight Castor oil...too dirty. Any of those other oils are great...Klotz R50, Klotz Supertechniplate (contains 20% castor bean), Amsoil Dominator, or Yami 2R. Break it in by varying the throttle for the first tank. Keep full throttle pulls to only a few seconds also. Second tank, drive it how you want. If you are running oil injection, i usually run a half tank of gas with a 50:1 premix just to be sure the system is primed. If you are running premix, I usually mix 32:1 first tank, 40:1 after that.

    If you want to use the Klotz BeNOL make sure you stick with it since it will NOT mix with other manufactures oils.
