Hi, I'm on my second tank of breaking in my Zeda Stage 2 engine, the bike has been running okay so far. Recently I noticed at higher rpm's the bike starts to make a whooshing noise that I haven't heard before, and whenever I come down off the throttle after running at higher rpm's for 10-15 seconds, the bike runs really choppy until its back lower. Also the last ride I took the bike started like misfiring? It was almost like turning itself on and off again then I pulled the clutch in and it died. I let it cool down for 5 mins and it started right up. Is my bike overheating? Is the noise from too advanced ignition timing? The bike isn't really running how it should at high rpm, and I know it's still breaking in, but this doesn't seem normal.
