Default New cam Grind for Raptor

I was gonna go with a Web 685 but I decided to try something different than any other person has.

The specs on my new web cam are:

IN lift .386 and 273 deg. @.050
EX lift .365 and 276 deg. @.050

It is close to a stage II on lift but has more duration than a 685. What do you guys think?

Have you gotten the chance to ride it with the new cam? Or is it just a test cam that you haven't gotten the chance to try out.

I should be getting it in the mail today! I'm going to Sand Mt. next weelend to try it out. I'm gonna call the shop that has a dyno in my area and see if I can't get it in there to jet it before I go.

I like increased duration and on a ported motor the increased time will make good use of the increased flow from the head. Like to hear more after test run.

I'll post results when I take it to the dyno or just go riding at the mountain.

Should do well for what you want, more top end but you'll lose some bottom I think.

I'll be watching for a ride report.[img]i/expressions/face-icon-small-cool.gif[/img]
