How best to remove carbon from PV components?
Hey folks,
I'm just going some PV assembly maintenance for the first time. How does one best remove carbon deposits from the exhaust transfer port valves? A wire wheel in a bench grinder? Oven cleaner? A hard scraper? As near as I can tell after a first inspection, it would be carbon building up on the valves and interfering with the cyclinder that would muck-up the mechanism, yes? Thanks. Dale |

Even a small shop sandblaster,carefully.

Get it bead blasted not sand blasted. Bead blasting is more gentle and won't remove metal. It will be done in minutes. Then polish the crap out of everything if you so desire to slow future buildup.

My 2000 XC/EC300 has not required any power valve maintenance. No carbon build-up ever. I have removed the parts and hosed them with brake cleaner twice. I love that engine. I have yet to open the '05, but I probably will this summer. I love that engine.

A wire wheel on bench grinder works well.

Contact cleaner to get the spooge off, and then as Eric said a wire wheel. Nice thing about the GG PV is its all steel, so you can't hurt it with the wire wheel.

Yes, brake cleaner did a great job of removing the oily buildup, and a wire wheel in the chuck of my drill made a quick job of removing the carbon from the steel port valves.
Thanks for your help and ideas. Dale |

Power Tune spray from your local marine dealer. Will break down any deposit including rust.

best i have used
straight up brake fluid.....it will eat chrome off of plated pipes or what ever it touches...if youve ever seen the street bikes that have it on them it trashes whatever it is left sitting on ,,swing arm,paint, chrome,..get the econo bottle at wal mart and dip your silencer core in it for couple days then clean it off...all carbon broken up and gone .
