The two big bolts that attaches the air cleaner housing to the heads. Those should hollow

 

Thanks, I'll have a look at them..

 

You should consider buying a service manual.

 

Boy, talk about an overly complicated design just to vent crankcase pressure. Thanks for posting that!

 

check the two breather tubes coming off of the rocker boxes they might be clogged

 

You're welcome - did you find the cause and get it sorted?

 

Nope and I've looked and checked everthing. All seems to be as it should. I haven't and don't want to go into the rocker boxes..

 

That's the only way to definitively check the rocker box breather system. Gotta raise the upper cover and unbolt the breathers. It's an 08 it has the older style plastic breathers.

 

whatever did you did out!?
