fishhead,
any info on how that setup was wired?
It's a Yamaha XS 650. I used an newer (electronic ignition) engine and wiring in in an older (1976) XS 650 and got rid of all the "weird" yamaha saftey stuff (clutch switch,kickstand switch, reserve lighting device,etc) that came with the newer wiring harness. Basically it is a stock electronic ignition wiring harness modified for use in this particular application.
The stock fuse box had 3 fuses and I added and extra fuse for the auxillary lights (with a relay). I had to "custom" wire alot of stuff like the handle bar controls. The right side control has an on/off for the lights (this is now the master switch- turns off all the lights) and the left side control(off a different Yamaha) has an on/off (was the master switch, now on/off only for the aux lights) and the high/low switch that operates, well, the high/low beam. Power to the left side light switches are turned on and off with the right side "master switch".
The fuse box originally sat on top of the battery, but the new fuse panel sits on the right side of the battery box under the side cover. The bike has a one off seat and the side cover is easier to remove than the seat is.
If you look to the rear of the fuse box (to the left in the picture) you'll see the rear master cylinder mounted to the frame (also hidden behind the side cover). It is actuated by a rod mounted to the stock brake pedal arrangement.
