    Just curious, has HD identified the specific bikes that were/are effected? or is it still a (EDIT) shoot from 2007 up through 2010?

    Ride safe and have fun.

    I don't have any inside information to support my theory but everything I have read seems to indicate 2008 and up "96"' cranks are better. As long as you don't go crazy with big bores or down shifting into 1st gear at 50 MPH by mistake, you will be OK. From what I read, if you go really big bore with any HD 96 crank, you should tig weld the crank pin just for the added protection.

    And since HD changed the run-out spec to .012", I would not expect to see a year or serial number spread of engines affected..

    Thanks, Hoople. My bike was manufactured in 10/08 so I'm hoping all were resolved or improved by then.

    Ride safe and have fun.

    The problematic years of the crank issues are from 2003-2006, from what time has shown us.
