Default Grey engine turning Yellow

I've serached and seen some posts about how to clean and remove the yellowing from the grill of the engine. Im not sure which method works best and im skeptical to others. If my engine continues to yellow, what would be another resolution to that problem? Could I in the furtue plan to get it chromed to cover the yellow? will the yellowing lead to rust in the future? Is it heat related (If my bike is running lean what do I have to do to correct it)? and its really just the left side...Where the horn is located. it yellows more inside the slits of the grill and stuff? any input from anyone will be appreciated thank you.

here is a link from the other Harley forum I use with pictures.

Could be quite a few reasons why this is happening, I could make suggestions like others have, although, you will need to do what's best in your individual situation.

Lots of factors to consider and without seeing the bike firsthand it would all be speculation.

Take it to the dealer, or a detailer and see what they have to say about it.

Sounds like a chemical reaction. Do you live near a chemical plant or refinery of any type?

From the looks of the pics, I suspect its road grime getting baked on the heads. Had the same thing happen to mine. So I painted the motor barbecue black.

Try that S100 spray bike wash. It will remove the carbon from the inside of your exhaust pipes so I'm sure it will take care of that. Follow the instructions.
