Yeah, that's strange indeed. There is no battery in the system? I suppose the only reason for the small battery in the US XT350 is/was the various state law inspection requirements that say some of the equipment must operate with the engine off. Your horn must not work with the bike not running then, right? I looked back a bit in the thread because I thought you had described it earlier and I just don't remember - was this the way the bike was wired stock, or were you looking for that info a while back?
