 Just wondering what thought were on using synthetic oil after break in.

SYNTHETIC IS THE ONLY WAY TO GO, THE ENGINES RUN HIGH RPM ALL THE TIME, AND CAMS HAVE NO BEARINGS THEY RUN IN THE HEAD CASINGS, I USE AMSOIL 20/50 MOTORCYCLE IT WET CLUTCH APRV AND I THE THE BEST OIL OUT THERE, WHAT EVER YOU DO DONT GO CHEAP ON THE OIL.

What model are you using?
The Cforce 400,500, Z500,U500 can use any Synthetic oil just find a good weight for your area.
The Cforce 800, Z800 and U800 us a wet style clutch and Need to use a Jaso ma1 or ma2 These oils have no extra friction modifiers added and will not cause slipping.
