    Valve adjusting headaches

    New-to-me 1980 GS1000G. ( The Beast)
    The bike didn't run nearly as good as I thought it should, so I'm cleaning the RS36 carbs, and checking vale clearance.
    My headache is:
    A): intake 1 and 2 @ .005" and .006"
    Ex 1 at .002", ex 2 @ .007"
    I've never heard of the clearance so far out of spec, so I stopped where I was, for fear of "I must be doing something wrong". Could carbon buildup be the culprit? The plugs are really fouled. { well, 3 of 'em. }See pic below.
    B): the #1 in and ex buckets are floating in "very old" looking oil, and all other buckets have a nice coating of clean, new oil. I changed the oil before last ride (20 miles, also my first ride on this bike.) I can understand the puddles, esp. since it's the kickstand side, but why is it so old/dirty after a 20 mile ride?


    1980 GS1000G - The Beast - GOING... GOING... yup, it's gone. I'm bikeless !!! GAaaahh !!!
    1978 KZ1000C1 Police - GONE !
    1983 GPZ750, aka ZX750A1 - restored, fresh paint... Gave it back, it was a loaner !!!

          Dirty oil: maybe sludge in the oil pan contaminating the oil?

          Sooty spark plugs: rich mixture?

          Valve clearances: someone didn't adjust the shims properly?

            This bike was sitting for awhile, yeah?

            It just looks to me like the PO (or his mechanic) didn't know what they were doing. Get the proper shims (keep those old ones), clean the carbs, seal up the air/fuel intake path, and you should be good. Barring any carb tuning, of course, since it sounds like your setup is not stock.

            Not sure about the oil, it might be that some of the old oil just hasn't worked its way out of the head yet.

            Probably want to treat her to a new set of spark plugs as well, they will be easier to read as you go about tuning and plug chops and whatnot.

              Sooty spark plugs: rich mixture? I think the P.O. fiddled with the carbs without a clue, and there was a 90 deg kink in the fuel line.

              Valve clearances: someone didn't adjust the shims properly?
              I'm hoping it's that simple... Thanks

                ..., seal up the air/fuel intake path.. Already ordering intake O-rings from Mr Barr

                    If those are indeed Web cams then the clearance should be .004"- .006".

                      I was going to guess that maybe the last 'mechanic' was confusing INCH and METRIC numbers and was shooting for 0.003 to 0.008".

                      I had not noticed the "Web cams" reference in his sig. Good catch.

                        Really ? Thanks ! I had a hunch they needed different clearance, but couldn't find it in writing, so I stopped thinking about it.
                        The readings I got make a lot more sense now.
                        ( again, see my previous posting ! )

                        Awful nice of Web to put the info on the end where you can see it...

                          And seeing how these are dated "9 94", I'm starting to realize the P.O. did NO maintenance at all. And rode the %^&* outta it for 20 years.

                            Those are drop in cams that can be used on a stock engine.
