Just bought last week 04 GS ADV, like it a lot so far. First question is, the high beam head light was not working at first thought it was burned out, but after taking it out and started to look around found a wire came on plugged. Works know, but the light is of one never seen before, the Clymer calls for a H1 bulb but its not, started to check around and found it is a high dollar one, don't know the size. The pictures show what it looks like, and don't know how to get the black wires out of the rubber boot it goes through, in the picture with out cutting it. So my questions are what type of bulb, how to get the wires through boot and can you change it to a H1. And also it has a one piece seat, can a two piece seat fit on it from other R1150GS. Thanks.
