450R Timing. Does the exaust cam need to be retarted?

[Narly R]

On the new yfz450r does the exaust cam need to be retarted like on the original 450s? Thanks

Nope. A lot of guys are dropping in an 06-08 YFZ intake cam and are leaving the intake/exhaust cam timing stock. Aside from going with aftermarket cams, that's about it.
