Got a zuma zrf70 at home. Having trouble with it running at wide open throttle. It starts fine. Idles fine. Revs slowly to bout half way fine. if u give it a quick blurt of the throttle it bogs and if u give it full revs it dies. At 3/4 throttle it spits and sputters and slowly dies down.
Ive cleaned the mainjet and pilot jet. I can see light through them both so there clean. I tired the carby on our other zrf70 and it done the same as that rules out an plug, coil ect issues as it runs fine with its carby. Could float height be an issue? is the spit and sputtering a lean or rich jetting issue?
