250-500cc 2014 WR300 with Baja Designs problems

I put the Baja Designs LED headlight on my 2014 WR300, they also sold me a "DC acc kit" it comes with a Reg/Rec, a small battery, and a switch. I hooked it all up and... The bike runs great with the lights on, but like crap with the lights off. Anyone have any Ideas?

sounds like a miss wiring problem on a switch or the switch activates a mode that create a load (big one) on the regulator (could be miss wired there)

with all info you give now I suspect a wiring problem

check your ground
most motorcycles use the frame as a ground and the issue is paint
check your connections at the coil, the engine mount bolts and headlight ground wires

I replaced the battery with a large cap and that fixed it.
