Cylinder heads are gloss black. The engine cases are not painted, they come from the factory in their cast aluminum color. The left/right engine covers are painted to match the rims, what Honda used to call "silver cloud" and which is now next to impossible to find unless you want to spend big $$$. If you aren't building a 100 point restoration, Duplicolor makes some silver paint which is pretty close to original, if you can find it. I think it was called "steel wheels" WP 318. Or just go to your local Honda dealer and get a can of what they are currently using on the CRF models.
