Just trying to consolidate some info from different threads and make sure I've got it right. For the HID setup, the low beam is the High Intensity Discharge type and the high beam is halogen. Mike103's tip is to improve the high beam for white/bright with the modified PIAA H11. I'm not clear on over taxing the system if you run spots with the HID on high beam.
Mike103's second tip to modify the spring allows for more adjustment.
For the spots, someone was going to try HD Part# 68208-04A and someone else suggested trying GE Siverstar bulbs. I don't think they have come back with results.
I tried the HD halogen spots on 2005 bike and actually preferred the stock bulbs. I was not successful in getting info on the Silverstar bulbs, but I'm interested in feedback from others.
To clarify my earlier post, if you have not rewired the spots to be on when the high beam is on
and powered off of the same circuit as the rest of the lights, you should have no trouble burning the PIAA H11. The spots are, I believe 27 watts each, totalling 54 watts. The PIAAs draw 55 watts (stock bulb is 35), but is still within 1 watt of what the system is designed for as long as the spots go off when the high beam is switched on.
It is a different story if one has wired the spots onto another circiut. In that case, there should be no problem with the addl. wattage of the PIAA and burning the spots all at the same time.
The HID bulb is wired completely independently from the headlamp circuit and has it's own fuse, so there is absolutely no problem with the HID setup.
For those without an HID headlamp, I believe you should be able to safely burn two PIAA H11 bulbs with the stock headlamp housing (provided you modify the bulb to fit in an H8 hole - one in the high beam hole and one in the low beam hole. The only question might be whether the plastic diffuser in the low beam can stand the heat generation of the PIAA. But I'd bet that it would be okay.
