Cleaning the engine, transmission and final drive
I don't want to take things apart anymore than I have to so, any kind of media blasting is out.
Anybody have any tips as to a solvent, cleaner or degreaser which may work better than mineral sprits? St.

Re: Cleaning the engine, transmission and final drive
I am just amazed at the amount of grime and crud built up in 36 years of riding in all kinds of weather, snow included. What I could see, I kept under constant control but it is the hidden stuff I am now becoming aware of. In an ideal situation, I would continue to strip things down and soda blast them. Since I am not doing a show bike restoration, I don't want to get that carried away. Powder coat and chrome will cost me enough not to mention seals, bearings and replacement electrical wiring. I still have not found anyone in my area to do paint. St.

Re: Cleaning the engine, transmission and final drive
I scrubbed off an inch layer of grease, road grime and dirt. Have been looking for something to get rid of the gray, decided in my case to let it stay. At least it is uniform in color now.
Short of media blasting or soda blasting none which are candidates for me at this time, I don't really know of any chemical which will restore the cases back to original shine. At least not anything I would want to handle or apply.
In my case, I used mineral spirit parts washer, S100, WD40 and Brake cleaner, with a combination of nylon brush and brass brush. Lots of elbow grease and a pressure washer helped. (I know, pressure washers can inject water Into engines, mine is open for rinse out with solvent so water is a problem.)
Maybe at 300K miles, I will soda blast everything when I do the next overhaul. LOL, fat chance of that happening. St.

The problem on my side is that the grey gets worse quite quick and turns into white powder... talking a matter of half days...srankin wrote: ↑Tue Sep 22, 2020 8:01 amAh yes, the gray oxidation, and pitting, I have the same thing on my RT, 36 years of riding in rain, snow, and road salt have not been kind.

Re: Cleaning the engine, transmission and final drive
Generally after I bead blast something I paint it with a clear paint. It holds up for a bit, pretty much after that, I use engine degreaser regularly to keep the engine clean. Perhaps after cleaning you could use a very light oil to coat the parts?
Oh I am sure there are others who will howl about bead blasting, as it has been said it tears up the surface much too much. I have never tried any other kind of media such as walnut.
Unfortunately, the new look does not always stay looking new if we ride in all kinds of weather. I also have salt applied to the roads in the winter to prevent ice. This is the worst thing to deal with. St.
