I have a 1340 Evo that will idle but when given throttle will bog out and stall.
I Have replaced the diaphram slide assembly ,the accelerator pump diaphram and the vacuum switch.
Have also adjusted the float and got a new pin. On top of that all also tried adjusting the fuel to air ratio with no results. After all of this took the carburetor off my friends bike and put it on mine then it ran like it should.
