    Crank Failure and Amsoil

    I just want to get some feedback gpr guys and girls. Spare two mins of your time and let me know what gpr, what kind of oil, injection or premix, how many hours of use with that oil, and if you had a crank failure, what kind.

    Example:

    2001 GPR 1200 / Klotz r-50 / Premix 40:1 / 51 hours / crank bearing went after 32

    2007 gpr 1300 / Amsoil interceptor / injection / 39 hours / no crank problems

    Just wanting to get some info. Also if you dont have a gpr you can still list. This will just give me a broader range.

    Thank you guys and girls for your time.

    Regards

    2000 GP1200R / unported / Amsoil interceptor / premix 40:1 / 180 hours / no crank problems (trued&welded crank)

    I did a 50 hour inspection and 100 hour top end re-ring, and a 150 hour inspection, excellent results.
    Powervalves were clean, excellent pistonwash, a bit on the fat side.
