i have a new 05 crf250r and on the right side of the
of the engine underneath where it says unicam there
is a hole where it looks like a bolt should be. the manual
shows nothing. i don't remember if my 04 had this.
i have gone riding once so far and no problems. is this
hole normal?

It's a drain hole from the spark plug hole on the top of the head.

I think your looking at where the smog stuff goes on the Ca models.

yep, it's a weep hole from the top of the plug. Just looks funny when you finally notice it.

here's a pic of the hole i think you're talking about:



and as stated it is the drain for the spark plug cavity.
