Hey guys, Im new and have been scouring TT for a while now and Im having trouble finding some info on the "timing" of the AP on my new '09 WR450F. I did what the servce manual said: threw a 3mm dowl under the float, turned the AP adjustment screw all the way in, checked for play on the linkage, then pushed lightly on the linkage while turning the screw back out till there was no more play. The bike is still boggy on the bottom end. Im at 5300' altitude and I just threw an '09 YZ450F pipe on it, modified the throttle stop and pulled the good ole grey wire. The bike still boggs. She has stock jetting but I figure that would be fine seing how it comes tuned for sea level and Im at a mile high. I was thinking of doing the Boysen quick shot aswell, does anyone run one of these? Any help would be great. Thanks in advance!
