2011 pro 800 with a Silber turbo sled ran good all day on the way back home it started bogging and died when I let off the gas. It wouldn't restart with out holding the throttle down. When it did restart it wouldn't build up any RPMs, smoking like crazy, running horrible the dash and air fuel gauge had no display however the head lights/tail lights and silber control box are working. I've check all connections and haven't found anything loose. Anybody have any ideas for me? I was looking at checking the voltage regulator?
