I think it is def a electrical prob. Bike starts on first kick n idles perfect but if i hit the throttle it revs 4 a sec then cuts out like the spark stops . It doesnt sound like lack of air or fuel. I can tap it very lightly and get it reving a lil but if i hold it at any throttl pos. it cuts out till i let go of the throttle ne helpm will be great i just bought this bike n redid the top end and havent been able to rip it up yet
