FOUND A SOLUTION Removing Carbon Deposits

You need alot finer than that. Get glass measured in microns not grit.
And at least 80-90 PSI

one-millionth of a metre (or one-thousandth of a millimetre, 0.001 mm, or about 0.000039 inch)

Where in the world do you get glass bead measured in microns?

The LAST time you run it before taking it apart,
with the bike warmed up,AND RUNNING, REV it up,
spray water from a spray bottle into the carbs.
Works best with pods you can take off first.

The water flashes into high pressure steam ,
Cleans piston tops , valves and ex. ports to almost like new,,,,,,,,
Well not quite ,but almost no scraping after tare down

PS. an old racers trick is to paint the piston tops with a thin coat of VHT .
you just get a very thin layer of carbon and it cleans up much easier next time.

that makes total sense. boiling water removes gunk from carbs really well, so why wouldn't it work on an engine? gonna have to remember that trick.

Oven cleaner, zip strip, old style Permatex spray gasket remover takes off carbon.

There was a thread, years ago, about squirting water into a running engine.

I've had really good luck with soda blasting. I like the peace of mind, not having to worry if I cleaned all the media out. Just a few glass beads could wreak havoc on their way to the oil filter.

If your turbo has water injection the pistons, ports, chambers and valves look like new when you have to take it apart........ but yes if I have carbon to remove I use a powdered glass bead :S (used till it's dust) :woohoo:

Micron, Mil, somethin like that? This place has 10 different grades of it. Heck, a 50 pound bag, lasts me 5 years. So it's been awhile. And It is close to home. Pick it up at the door.

Blasting Abrasives

ALUMINUM OXIDE - Hardness 9; Size range- 16-240 grit; Shape: angular. Aluminum oxide is our most popular cleaning blast media. We only offer virgin quality material which contain none of the many impurities found in reclaimed or reprocessed Alox (also known as Aluminum Oxide.). Aluminum Oxide conforms to all major Industrial and government standards including, MIL A21380B and ANSI B74. 12-1982. White Aluminum Oxide is also available. Specially treated for removal of Iron and is used where surface contamination is unacceptable: cleaning and deburring electrical circuit boards.

SILICON CARBIDE - Hardness 9; Size range: 16-240 grit; Shape: angular. Silicon Carbide is an extremely hard sharp grain that is more friable than aluminum oxide. For use in blasting of extremely hard materials including cemented carbides.

GARNET - Hardness: 7.5; Size Range - 5 sizes from 16 to 100 grit; Shape: Blocky particles. This natural mined material is fast cleaning and is an excellent alternative to sand and coal slag (black beauty). It is not as effective as Aluminum Oxide on difficult applications. Garnet is used widely in waterjet cutting and has a higher Iron content than Alox while sizing is on the "loose" side. Sold usually in bulk containers, but bags are available.

GLASS BEADS - Glass beads are formulated from chemically inert soda-lime glass to produce a metallurgically clean surface for parts and equipment. The beads are spheres of uniform size and hardness to impact the surface of the part. Metal Preparations glass beads meet OSHA standards for cleaning operations and release no free silica or toxins that may harm workers or the environment. Breakdown of glass beads is generally caused by fracture and does not contaminate workpieces. Another advantage of using glass beads is the disposability, spent glass is environmentally friendly as compared to chemical cleaning methods. Normally this simplifies the disposal which results in reduced cost and required paperwork. Glass beads are often used for stress relief. Metal Preparations has available mil-spec (MIL-G-9954A) glass beads at absolutely no extra charge.

Hey 4, I knew you would like that, were on the same page!.
Speaking of unsafe, I had an unsafe Kawi KZ dirt drag bike years ago.
I added beer and other stuff to it, then had a blast! And I lived to tell about it.
I posted the pic a couple of years ago. You want the unsafe details, I'll share them.
Nothing bad or out of line. Actually quite koool!

Crushed shell media (like walnut) works well for inside the engine parts where you don't want abrasives left over in the engine.
It might take longer BUT its safe as heck , you cant hurt parts , all it will do is clean the part,
Also it might work in a blaster without having to change the nozzle .

Plus its bio.

I tried ALUMINUM OXIDE in the cabinet.

Forget it.

Just a friggen mess with a black residue all over the inside of cabinet. Im going to use soda or glass and if it needs more than that.....going to my bud Craig to do it.

My compressor is about 20 to 30 psi from getting the job done. I need 100 psi, but my compressor can only do 75 psi constantly takes way to long to get stuff done.

Do you need a different gun or tip to use soda?

Do you need a different gun or tip to use soda?

Yes ,,, much smaller tip (nozzle) same gun.
BUT a smaller nozzle means LESS CFM
So a not quit big enough compressor might keep up with it.
