Ok my 87 mojave I bought is really starting to piss me off. Here's my current problem. The bike will start out and idle fine. Then you'll run it up at 1/2 to full throttle for about a mile then the fuel will just stop. The bike still idles but when you hit the throttle it doesn't do anything. Then if you hold the throttle wide open for 20-40 seconds the fuel will come right back and act normal for about 10 minutes then do the same thing again. I've checked the petcock and fuel filter and there isn't any blockage. Does anyone know what the problem could be????
