probably this is too late ... but currently want to upgrade to HID on the bike.
This seems to be the user manual from DDM. probably applicable to install their kit. I have not got mine yet, did not know that it ships from china.
Looking to install this once received *dunno how long*.

By the way, from the fz6r manual, we can have 35W or 55W bulb.
In fact, on Fz6r accessories from yamaha website, it offers PIAA bulb that rated at 55W such on below url ... I wonder if the DDM 55W HID can be used on the bike. I purchase only 35W though, not sure about the heat from 55W which may risk to damage the plastic housing.
