Anybody got any tips or advise on the best way to clean the carbon deposits off the head and piston-crown.

While I'm waiting for my new crankcases I need something to do!!

I would think media blasting. It is similar to bead blasting, but uses a plastic media. It is said to remove very little if any metal. I would still tape off the gasket (head) and skirt areas (piston).

I've seen people use wire wheels :), but would not advise that.


86TT225, 99WR, WR timing, throttle stop trimmed, air box lid removed, White Bros head pipe, silencer and air filter. Odometer and headlight removed. Moose hand and mud guards. YZ stock tank and IMS seat. Renthal Jimmy Button "highs" and Renthal Soft half waffle grips. AMA, SETRA.

A gasket scraper and a little elbow grease works well too.

I worked in a cylinder head shop where we used a high pressure hot water and baking soda to non-destructively clean cylinder heads.
Of course this requires complete disassembly,
but you were going to do that anyway, right?
Otherwise I would not even waste my time scratching around.
Any abrasive media will leave remnants in the head, beware...
I have learned this the hard way, bucket motors hate beadblasters...
