Question about 2003 Yamaha YZ 250
My yz250 will run and idle. But everytime I put a load on the motor or open the throtal it cuts out on me. I have pulled the whole carb apart and rejetted and everything I can think of. It has compressio. I don't know what else to do but need my bike running right
check crank seal (air side)
check correct fuel flow

Pull the fuel hose at the carburetor and place the hose end in a small clean can or bottle. Turn on fuel tap--should get thin stream of fuel. If it just drips, the trouble is probably a plugged fuel screen above the bowl of the fuel tap. Remove the screen and soak in carburetor cleaner, then replace and recheck fuel flow. Worst case--replace the fuel tap (drain the tank first).
