well, I checked the code, its 44 for the 'bank sensor', which I did in fact remove. Is it anything other than an average tip sensor (to kill the bike if it's not upright)? any reason besides the obvious "kills the bike in a crash" to keep it? The bike's RPMs are a little unstable too, but I'm about to reset the TPS to see if that helps. still no luck finding where that breather plugs in :( Thanks guys!
