My WR450 stalls often at partial throttle, like when just about to pull away from the lights or when negotiating a really tight offroad section.

What's the most likely cause / solution?

The plug colour when running off idle is pretty dark brown. At anything other than partial throttle there's no drama.

Also, would installing a PMB silent insert be a possible cause of this?

Mine had similar issues and it turned out to be the accel pump diaphragm.

I'm sure it's a carb issue- you just need to track it down.
