I have a standard and run a 80/100 but it will require replacing the bulb socket. Napa makes a high temp one that is easy.
I ran a 100/110 for a while, wothout mods.... but it went thru bulbs. I am back to a 55/65 or whatever is the stock H4 numbers. I added small lights in odd places on my Valk with custom mounting. It makes my bike look DIFFERENT, and I think that gets me noticed.
I have a SilverStar Ultra in there now too, and I think that helps as well.
My IS REALLY puts out the high beams though. I am not sure what's in it... but man-o-man, compared to the STD it's a FLAME thrower. and my STD ain't a slouch when it comes to light output.
