I have a Chinese telescopic H4 HID retrofit kit. It has served me well for as long as I've had it (almost 2 years). Here's my installation saga complete with beam pattern pictures
I did have some problems with one or the other of the HID capsules not firing up at start-up occasionally, but that was resolved with my custom time delay circuit farkle, which delays the headlights from coming on for 10 seconds after the engine starts.
The beam pattern problems with the high beam are not caused by the HID retrofit. It is a function of the Yamaha headlight reflectors that is actually also present with the halogen lamps installed, but because the intensity of the HIDs is that much greater, it makes the drop off to darkness that much more noticeable.
I have played around with using a fixed low beam in one side and a telescopic one in the other, and for night time riding that is a good compromise. In the bright daylight, however, I do want to run with both bulbs in high beam. So my next modification will be to add a switch to allow me to enable and disable the right side telescoping solenoid. When disabled it will have to send it the correct signal (voltage) to hold the solenoid in the low position.
