I'd like to know the answer to this question on this two year old thread as well.
I have a 2010 FE570 converted to a snowbike. Bike was running great until yesterday. Noticed that the mount point on the right shroud had come out of the mount and the top of the air filter was slightly exposed. Night riding the evening previous the snow was coming over the top of the bike, but I did not see the slight gap in the shroud exposing the top right edge of the filter. The following day, warmer and sunny went riding again. At the top of the 2500 foot road climb, the bikes FI codes started blinking 9 times for the manifold error. Then the bike cut out, had difficulty restarting and ran rough. Got it down off the hill with the FI light solid the whole time, trailered it out.
Today I started it on the trailer, but giving it gas it would cut out. Took off the seat and inspected the air box. A small amount of milky fluid sitting in the cup holder below the filter. The filter felt damp to the touch. The whole time the 9 blink code kept going off every 3-5 seconds. With the air filter off I gassed the engine and the FI light stayed on solid. Finally put it inside my enclosed trailer and tried starting it again. The bike started, then cut out when I gave it gas and now won't restart at all.
I am wondering if wet melting snow got on the filter and somehow moisture is in the engine.
1. What EXACTLY does the manifold light mean? Where should I start looking for that problem?
2. Can you drain the gas and run HEET in a FI Husaberg?
3. ANY other thoughts or suggestions? I am 10K into this Timbersled and I am deadlined 4 rides into the season
