2011 yz250f bog

Recommended Posts

Only have about 5 hours on bike. When i first bought it noticed a bog when throttle is blipped open. 1/8-1/2 throttle. Just installed R&D racing power bowl 2 and adjustable fuel mixture screw. Have only ridden bike in cold weather(30-40 degrees so the stock jetting may be perfect for warmer weather). Not too sure where to go from here, jetting is not one of my strong points.

2011 YZ250F

Main jet #180

Jet needle clip postion NDJR-4

Pilot Jet #45

Fuel Screw 1-3/4 turns out

Leak jet set at 2 1/4 turns out (#70 stock)

Elevation sea level-800ft.

Temp currently is 40-50 degrees here in MA (coming into spring will soon be 50-70, and summer 60-90 degrees)

I dont want to just start adjusting without some experienced input. Any advice would be greatly appreciated.

Lift up the subframe, with engine off, whack the throttle and notice the apump fuel stream in the bell of the carb.

It should last .8-1.2 sec and shoot all the way into the head.

If it does not shoot far enough, you leak is too small. Turn the adjustable leak screw in.

If it hits the slide, turn the linkage screw under the throttle wheel cover clockwise. If it is way behind the slide lifting, turn it counter clockwise.

If it doesn't squirt at all, you have a clogged nozzle.

Never judge bog on a stationary bike, only when riding.
