Gents the best motor cleaner is........?

petrol and gurnie 

If you have a silver motor, like me, wash it down with household grade kero and a clean paintbrush, hose it off, then use s100, then dry with a leaf blower. Works for me.

I just done my black motor. First I mixed CT18 truckwash with water in a sprayer@ 50/50 then washed it off with a pressure washer then I dryed the engine with air compressor.
Then left it in the sun for an hour just to make certain it was dry then sprayed harley engine brightner on it as per instructions. Left it for an hour then started bike and when for a run.
Was very impressed with the result. DON'T SPRAY ON HOT ENGINE

C-18 is the Best
