Finally I have the bike assembled and was able to try it with the engine running. When I use the full beams it does it only randomly, maybe 2 times out of 10. But when I use the passing button it does it all the time. However I didn't get a chance to check the battery yet. Only thing I noticed is that when I put it on the charger it starts to charge and in 5 seconds it switches to maintenance / trickle charge. So I guess the battery isn't holding the charge. Interesting thing is I started the bike with it a couple times and it always starts on first try without any trouble ... is it possible that the starter pulls less from the battery than the high beam halogens?

Hi, any news? I seem to have the same issue with full beams ...
