[Ducati] Cleaning out carbon buildup

[Rich Roberts]

Any good solvent like brake cleaner etc  and a ss wire toothbrush style brush is what I use and elbow grease takes a bit but it gets it all off eventually. I do valves and pistons this way. Valves you can scratch it off with about anything hard edged , brass is not going to damage a thing and most soft steels with an edge will scrape the crap off with no problems. and not damage valve in any way as they are pretty hard. Even the aluminum piston is fine with a nice fine ss stiff brush.  A wire wheel on bench grinder works well for valves as well. For stubborn valve stuff I have used the edge on a 6 inch pocket rule scraping and it did the trick. You have to be creative sometimes, nothing magical that I know of that is simply spray on and off it comes.

and combustion chambers on a 2 valve head? I have the heads off and wanted
to clean everything up, lap the valves, and do a thorough inspection.

Thanks!
