I haven't yet found way how to assembly hids without getting serious trouble with bikes speedo.
I know the problem you mean, the lamp flashes and the clocks go blank. With my first hid install (h4 hi/lo) I had this when I first switched on the ignition and after that, every time I had left the main beam on when the ignition was off. If I left it on low beam it was okay. I think it was something to do with the solenoid for high beam allowing the capacitors in the ballast to discharge. After a while it started tripping the clocks all the time.
With the new ballast it is back to only tripping when left on high beam.
The ballast is mounted on the back of the alloy plate with velcro but I don't believe it is down to mounting it too close as I had it mounted there without any problems using a second battery to power the light. This suggests it is likely to be a spike going through the wiring. I might try a car radio rf suppressor on the lamp wiring.
