header cover
 

my buddy just took off the cover on his 95EX and i wanted to know if this is a bad or good idea. he also took off the flat plastic piece that covers the fron grill on the inside of the engine. what do both these parts do?

RE: header cover
 

The grill one protects the radiator, you can cover that up with mesh if you wnat, i thnk that looks good.

That other piece is just a heat shield. It's always a good idea to protect your engine/parts from heat, but in all honesty its not necesarry. They usually just get in the way and rattle anyway.
