I was toying with the idea of a switch to the coil so it cuts the main spark and puts neat fuel down the exhaust but i think the look of the flame is shite although big. I think the flamer kit is fine and produces big yet nice yellow/ orange flames
Its a pain in the arse when you have to dip the clutch rev the tits out of it flick the switch and pump the throttle just to get a blue flame that sounds like a bunsen burner and in my experience in another s12 of using this method its a pain in the arse
Normal flamer kit, flick ya switch and back of the throttle

BOOM
Here is the kit i have:
