What wattage bulbs are you running? I used to have a CR500 bike with an e-line and I was always told it only puts out about 180 watts. I had two halogen lights on it and I had a 55 watt bulb in the driving light and a 100 watt in the pencil beam. The e-line handled it no problem.
Already said it, but I have to say it again, awesome quad!
