anyone got a spec sheet for a 2011 Pro? I'm putting new pistons in and a head, anyone got the torque specs for the head bolts, and the specs for the cylinders and piston sizes?

pistons
bought Wiseco 85mm pistons, have a buddy that runs a small engine shop, as soon as I get the pistons he will send them with the cylinders to a machine shop to have them fit properly (including the rings). Everyone I talked to recommended Wiseco or Wossner thoughts?

Wiseco piston get a bad reputation from the past. The forged piston grew to fast, or the clearence to tight and they seized. The alloy the use now does not expand as much, and with proper clearence they will be fine.
I wouldn't let them go more than 1500-2000 miles without a teardown and check.

Break in?
any break in tips for new pistons? Other than double oil and and take it a little easy I thought I might get some aviation fuel (100 octane low lead)
