WR450 Valve Timing

1 post in this topic

I'm trying to build a Virtual 4-Stroke model of a WR450 engine to be used in a restricted format in an FSAE car.

My main problem at the moment is that I won't get my hands on the engine for a few months so I have to get all dimensions etc. from other sources. :cry: I've managed to get just about everything I need except the open and close angles of the valves in degrees of crank rotation. I've been trawling through the forums and seen plenty about advancing and retarding the cams but haven't come across any numbers for the stock configuration. Does anybody know these? If anyone has the YZ450 timing I wouldn't mind getting this too.

Cheers

Tal
