2002 YZ250 bogs at full throttle

Recommended Posts

I need some help.  Rebuilt top end, just rebuilt entire carb.  Rides great at low (1/4 -1/2) throttle.  Once you pin it it stumbles and bogs right down.  Not an issue for me because I never ride wide out, but would like to get it figured out.  Stock rebuild kit, bike has aftermarket fatty pipe. Inputs please.

Bogs down like its drowning I guess. I tried to attach a video here to no avail. Stock rebuild with 178 main jet, 50 pilot, clip set at 2 per fact specs. I just found a rec online by fmf saying the stock jets are fine, also advised clip at third. I cant imagine it would run that poorly from just that though.
