You don't say how many miles on the motor, if any, since rebuild... With the lack of pertinent information, I'd have to guess that Its either a bad head gasket or the rings are gone.

Check this post for the specs.

Hope you can read this. I couldn't get it any bigger

Check PCV valving to the intake manifold most often the diaphragm is broken which allows extreme vacuum to be applied to the crankcase.Will cause many codes relating to lean fuel mixture bad map readings fuel trims way off. With the engine idling remove the oil fill cap and note the vacuum. It should be very slight.;almost undetectable. I know there are specs relation to in/hg but if you don't have the tester the spec is unusable. Replacing the valve is difficult/expensive. I have replaced many and they never get easier.

ok , the valve is easy to test and clean but is only 10% of the path.

my bark test works.
i remove the EGR valve see 2 ports there. (twin holes)
one is vacuum side, (intake) the other is exh. side.
i plug the vacuum side, and start engine
this is what i call the bark test. if the exh port barks load ,it may be good. if dead, or weak, it is, fix that now. clean path.
if that works ok , i then check the vacuum path port of carbon blockage. i rod it out with a flex cable.ask
the electric side test are below.

that is the FSM. burn it to cd, and run the setup'

have you add anything or adjusted anything? spray some soapy water at the intake seals while the bike is running (idling) if the idle changes you have intake seal leak and if you have added an new air filter other than stock you may be running to lean and need to rejet

2006 specs:

intake valve clearance 0.10-0.15mm
exhaust valve clearance 0.17-0.22mm

Hi,
Your valve clearances should be:
Intake .08-.12 mm (.003-.005 in)
Exhaust .12-.16 mm (.005-.006 in)
I usually start all gaps in the middle of given specs, then fine tune from there.
Hope this helps

Measure the exhaust back pressure. Do you have an old O2 sensor? If so just break the ends off of it so that just the tube is left sticking thru the center. Install it in one of the O2 ports and hook a vacuum/pressure guage to it. Should read les than 1 psi at idle and no more than 3 to 4 psi at WOT.
