Do that for maybe 5 minutes. If you want - put a floor fan on a crate and blow some air onto your engine while you do this - but its not absolutely needed.

The water will turn to steam and clean the carbon out of the head, piston, cylinder ridge, valves and seats. This trick has been known at least since WWII when mechanics noted the pristine innards of fighter engines that had battle boost (water injection) to get a few extra HP from their motors. It works.

great trick and it will work very efficientlly when done as described. but if you squirt in water as a solid. then you will have a problem. i have stopped carbon knock in older cars this way for years.

My understanding is that the '04 and up heads are a higher flow head. I think you'd be better off cleaning up what you've got rather than go for a lower flowing head in the earlier model heads.

Read this with the understanding that I am NOT an expert on heads. Hopefully Dan from NRHS will chime in soon. If not, I'd suggest PM'ing him before spending money on the '02 heads.

That's only true of the 1200 heads. Rubber mount 883 heads are the same as the pre-rubber mounts when it comes to the chamber and ports and valve diameters.

Thinkin about it it does make sense, I always wondered how the water injection worked on the old planes, I guess it just helps cool the air and maybe provide some more compression in the engine. I'll keep that trick in minde hopefully it'll come in handy. for now I've already taken the heads off and removed 95% of it by hand
