    Hi, I just picked up a cd owners manuel for my brothers 2005 r 1200 gs . I hope to do his valve adjustment to save him some $. I do all my own maintenance over the years but never on a BMW.
    My questions on doing a valve adjustment are > Is there a easier way to make sure the bike is at TDC than sticking a special tool in some hole, if not the manual really doesn't say much and is there only one hole , in other words when I move to the other side am I using the same hole or is there one on that side also??
    The valve adjustment seems straight forward but then it says to Set the valves actuated by a common rocker arm to exactly the same setting but doesn't show where ( no photo of this being done ). If the inlet valve is .15 that would mean the rocker would be the same ?? and .3 for the exhaust. And what kind of an adjustment is this rocker arm ? ( locknut like the valves ?? ) this is what this section looks like. Thanks for all feedback !!!!!!!!! is there easier write up to follow or video made by somebody from this group. Thanks agin !!

    Get the write up by Jim VonBaden. Excellent, with pictures. Also the write up in the hall of wisdom by JonJen and company - another excellent source. Lot's written on the subject. Good luck.

    Jim's write up is excellent, you won't go wrong with it.

    However.

    Setting up TDC need not be a hair splitting proposition, close is good enough.

    What I have done.

    With pulgs removed and having engaged 6th gear I rotate the engine to where I see the intake valves closing, which means that TDC compression is coming up (where you, ideally, want to set the valve lash). I put a screw driver, or a long soda straw, in the plug hole and work the rear wheel, gently, until I feel the piston come up and then fractionally decend--you can go back and sneak up as often as you want, but make sure that you stop moving the engine after moving the rear wheel only in the forward direction, this insures that the can chain slack is out of the equation. You can safely set the valves at this point. Don't forget you are setting the maximum clearance so you can check your work by measuring again when, say, the exhaust valves are at, or near, maximum open.

    I am a fan of the hash mark on the cam, but anywhere between 2:55 or 3:05 is as good as 3 O'clock, given that 3 O'clock can be somewhat subjective.

    Best wishes, you'll do great!

    When the exhaust valves are at, or near, full open the intakes should be at, or near, full clearance (lash). Similarly when the intakes are at, or near, full open the exhausts will be at, or near, full clearance (lash).

    The point being that if you set the lash correctly it will be the maximum measurable at any given point during the cam cycle while the tappet is on the cam's base circle. The base circle can be as much as 180+ degrees of cam, or 360+ degrees of crankshaft rotation.

    Hope this helps.

    TDC is nice. All you really have to do is have the rocker on the base circle of the cam. Anywhere on the base circle will do. It&#8217;s just an internal combustion four stroke engine. The principle is the same.

    Measure the gap between the valve stem and the flat on the bottom of the adjuster.

    Just curious, why do we need to remove the spark plug for valve clearance?

    Any expert here care to share on this?

    It/they are removed so it is easier to rotate the rear wheel in gear. Otherwise, the engine's compression makes it almost impossible with the plugs in.

    Remove them and observe them...they tell volumes about what is going on in your combustion chambers.

    A regular socket will get stuck in the plug "hole". You need a thin walled deep well socket..... You can get 'em at most auto parts stores. ---- But, maybe not in Singapore! I havent been there since 85. Is Change Alley still hopin'?

    I remember some pretty exoctic stuff from my visit. The best part was when an old man told my fortune. He was at the end of an alley, had a little mobile fluttering in the wind and had a few candles lit on a very low table. A couple of other fortune tellers were there as well but NO LOCALS (mostly Malay, Chinese etc - people who didnt speak any english etc). My interpreter told me that the locals wouldnt go near these people becasue they didnt want to know their futures. They really believed these people are seers. ANyway, the dude couldnt speak any english. My interpreter said it was $5 Sing for the dude to read my palm. I paid up and he told me some very interesting things about myself which he couldnto have known from the way i was dressed (jeans and a polo - no watch no ring). He nailed my occupation and specialty. He told me I would be married in a year (I thought him nuts for that) and several other cool things. Then, my interpreter asked me if i wanted dude to read my forehead - only $5 Sing more..... Hell yes, in for a penny, in for a pound! So, dude read my forehead - I'd heard of palm readers all my life. But, foreheads?

    Anyway, that event is etched in my mind vividly today. It looked to me l like i was in the middle of a scene from some James Bond movie - it had that exotic, mysterious and almost dangerous sort of feel too it.

    The folks in Singapore were very, very nice to me. At 6' 6" I towered over my hosts who called me Rambo.... Rambo was big at that time and the folks in SIngapore were not to chummy with the Vietnamese if i understood correctly. SO, Rambo was a good nick name not an epithet.

    I remember pepper crab, sing ice tea, cuttle fish balls and huge deep fried grouper served on a banana leaf and eaten family style with a whole group of folks from the office. I remember going over to Sentosa (sp?) and walking among the old coastal defense works and admiring the beauty of the place in general.

    I also remember that there were a great many small work/delivery type trucks with yellow lights on top. The locals told me that these lights would come on if the driver was speeding... Seemed like they were all flashing. I suppose this meant the police didnt need radar as each drivers vehicle told on him.

    Durian is good. Smells like a sewer but tastes great. The fruit peddlers were everywhere and everything on their wagon was awesome.

    Two other things stick out in my mind: The misery of a neck tie- never wear a neck tie in Singapore - the only thing its good for is to wipe the sweat off your forehead. The other is a large bottle of Carlsberg beer, some (what I think was chicken) satay and peanut sauce on a table along the various side walks.:dutch
