Virtually eliminates the possibility of getting the gasket out of place.

    When the exhaust valves are closed so the rocker/adjusters are "up", the adjusters interfere with the forward lip of the cover, making removal a "Chinese puzzle" as DirtFlier describes it.
    Thanks for the tip! I put it in my notes....

    Which COG National were you at, Chris? I've been at several of them, starting in 2000 when I went to Cedar Breaks and Mountain Home, but didn't make it to Natural Bridge. After that one I went to Klamath Falls, OR; Montrose, CO; Centralia, WA; Fortuna, NC; Hill City, SD; Frisco, CO; and Tomah, WI. if you were at those, we may have met before we met at Spearfish (in '12?).

    Never went to one, but I heard the stories of wild women and hard liquor!

    Re: Checking the valves

    Dumb question.....

    per the 06 Manual - both cold

    intake - 0.006 in (0.15mm) +/- .001 - So the clearance can be .005 to .007 ?

    Exhaust - 0.008 in (0.20mm) +/- .001 ...and here the clearance can be .007 to.009?

    Correct.
    Always good to make sure you're doing it right.
    It is too much trouble to do it over.

    Re: Checking the valves

    Did the first check the other day.....at about 2200 miles....the rear cyl. intake was was tighter than the exhaust....the front cyl was perfect......

    Observations..... the rear valve cover can be removed without removing the throttle body...not so for the front...adjusting the front cyl tappets is gonna be a real pain...

    Re: Checking the valves

    It's a common mistake for mechanical newbies to NOT have the cylinder being adjusted on TDC compression. I'm old school so I usually turn the crankshaft through several revolutions counting to myself...."intake-compression-power-exhaust"...then start looking for the marks as I approach TF or TR. Many thanks to Mr Watkins my Auto Shop teacher from high school when we still had wood burning cars!

    Doing away with shop classes in jr high (middle school) and high school was and still is a crime!

    ps. in regards to the throttle bodies, I remove them but leave all the wires & cables connected, then place the unit on the side side of frame. And If you've never done it previously, the band clamp for the front throttle body is a real joy because of space and being blocked from view.

    Re: Checking the valves

    Always look for the intake valves to go down and once they begin their upward journey, look for the timing mark.... gets TDC every time.
