Hey guys, I currently got a vl that runs fantastic on fuel, but when i switch it over to lpg or start it on lpg, it idles like a pig, batt light comes on and then stalls. when I accelerate it just coughs and splatters everywhere. ideas what it is? not too savvy on lpg diagnosis.

check your water/coolant, mixer might be freezing up. if your mixer is frozen, poor some water over it. Also are you flicking it to gas instantly, or letting it burn the fuel 1st before flicking over to gas? Hope this helps
