    Setting valve adjustment on 16 valve engines

    I am doing a valve adjustment on my '03 K1200GT and looks like I'll need to replace some of the "Cam Followers." Anyone have some of these "Cam Buckets" left after selling your bike? I'd be interested buying them. Thanks; Steve

    The moderator will probably ask you to place a Want To Buy ad in the Marketplace.
    Here's the link http://marketplace.bmwmoa.org/?tabid=137

    Another good place is i-BMW. http://www.i-bmw.com/index.php?

    I looked at your ad; you're going about it wrong. There are way too many sizes to just buy used ones hoping you get something you can use. I have a bunch I could sell you but they'd probably be useless.

    You need to figure out which sizes you need. Measure the clearances, remove the buckets that need to be adjusted and get their sizes. Then you can determine the bucket sizes you need to find. Chances are your buckets for a particular cam only vary by one size (the line boring is pretty well done) and you'll need one size thinner. For instance, that means that if most of the buckets on your exhaust cam are 2.85mm, you'll need a few 2.80s. Buying a bunch of 2.95s from me would be a waste (but it would let me unload useless stock).

    As soon as I can get the cams out and measure the followers I have, I plan to edit my wanted ad with the sizes I need. Just a lot else going on this time of year, so haven't gotten that done yet. Thanks for the tip!
    Got the cams out and need 2 shims, both 2.750 mm; part number 327666047. Have updated my "want ad" too. If you have that size, let me know. Thanks All!

    The size is etched on the inside. It's good practice to measure anyway, but it's extremely unlikely that you will find one to be mismarked. If you don't have a micrometer that will reach in there, don't sweat it. Just go by the marking.

    As I recall, the recommendation for the chain guide service/replacement is now 32,000 miles. They did not have this guide, to my knowledge, until around 2010. By which time I was well over 100,000 miles.......

    No; I sold one of those jobs in 2008 and it wasn't a new thing then. In fact it was already considered unnecessary that soon.

    BMW calls for the replacement of the Chain Tensioning Rail every 36,000 miles but most owners do not replace it that early.
    We had around 90,000 miles on our 2003 K1200RSs when we traded and they still had the original rails.

    so a slight valve "float tic" - i'd guess weak springs - my e30's do it too - so its change T chain & rails when i change clutch - heck if i live that long - thanks all merry HOHO

    You set valves with a "gap". That means it goes from zero contact to some contact. That can produce a slight "tic". With Airheads quiet valves meant the gap was too small or non existent. With later models not so much but I consider slight valve noise to be normal.

    Check the gaps. If in spec, ride the thing. If not, correct the gap.

    bike sat for 10 yrs (before i got it) springs on 1 or 2 valves might have been fully open - - may have taken abit of the "spring" out of them -is what i thought. i only happens w/ no eng pressure "eng float" no acceleration no deceleration
    low throttle 50 mph - just "floating along" about the same time the clutch rattles a bit ie: no stress on eng or drive train. i dont run the snot out of it - chipped, better injectors & pump , e 3 plugs, k&n - its WAY faster than i need, dyno'd at 168 @ rear wheel. and now it gets 48 around twn & 51 hwy -
    i was just wondering - now i know-- typical BMW - if it aint making a sm bit of noise - it aint running -
    thanks folks - merry x mass & happy holidays
    bmw forever e30, e28 & k12gt

    That's a huge increase on a K1200 brick engine.
