Do you have a flame arrestor? If yes, it is possible there might be a leak and the water is getting to the flame arrestor. Run the engine on the flush and check for water leaks at both the head & the exhaust. Sometimes the heads can crack or there might be a small pin hole in the rubber exhaust boot causing water to get to the flame arrestor. You might want to check your engine compression as well....just in case.

Kaz you may have a leak in those heads. Dry them up good and check them out again. Make sure the water fittings are sealed well on the head. Could be the water is coming from somewhere else. If you have outer wears put them on the arrestors for now until you solve the leak issue.

Kaz it should be no problem to go back to the stock head. Sorry but I am not up on the controllers so I can't give you any advice where to set it, somebody will jump in and help.
