Those of you with a 220 I have a little message for you... You need to check something out on them that is potentially dangerous. The battery vent and other tubes are routed dangerously close to the exhaust system. The battery vent was touching my exhaust when I stopped for a few minutes and when it burns it emits a deadly invisible gas. I didn't know what was going on because all the sudden my lungs starting burning and I could not breath at all. I thought I was gonna pass out or something I thought there was somethign wrong with me, not the quad. I only knew what it was when I got off the 220 and saw a little stream of light colored smoke coming from under the quad. Once it gets into the air it is invisible like I said earlier and is EXTREMELY dangerous gas. If I were you I would check to make sure your battery vent hose is properly routed away from the exhaust.
