2006 WR450 with YZ throttle stop sticking WOT

Recommended Posts

Hello gents, I've read through similar posts on this topic but I'm still stuck.  I've bought a used '06 WR 450, and most of the free mods have already been done, except a very short screw was used to fill the throttle stop screw hole.  Twisting the throttle wide open led the throttle to sticking as the ap pump cam goes past the lobe and gets stuck.  In another post about this, they were convinced that the lobe had been shifted on the shaft, but the cut-outs in the lobe where the pin is inserted are still lined up on mine.  Everything appears to be correct, but with the new YZ screw that I ordered the AP pump cam is still getting stuck on the backside of the cam lobe.  What am I missing?  Thanks.

Hello again.  I fixed the issue by bending the tip of the ap pump lever to be a little bit straighter, which prevents it from catching on the backside of the lobe.  Maybe it got bent from previous tinkering, I'm not sure.
