    Depends - the GTR 1000 was notorious at one time for blocked oil feeds to the cams. A friend had one go that way, and after he turned his considerable expertise to it, the repaired engine did another 100K. That was a known fault though, and I've heard nothing similar about these GS1150 lumps, so if the wear pictured is due to razzing it in hot conditions with cheap oil, the whole thing might be knackered.

      BiomedDR - that's my worry. I think I need to pass this project onto someone with deeper pockets and more engineering skills.

        Grimly - this bike came from the hot part of the US and the PO stuck this massive oil cooler on it:



        which is twice as big as standard. You might be forgiven for thinking there were temperature problems and indeed I do wonder what the bottom end might be like. There were some rumbles which can be heard here at around 2:24 - it doesn't sound too good:

          I had a set of brand new Webcams that developed similar damage after extended stator testing. I was doing the Series v.s. Shunt R/R comparison. Beyond the lobe dame there was cam bearing damage to the saddles. I used some 800 grit emery cloth and carefully worked the saddles. Was the paper so you don't get abrasive everywhere and wipe it out good after. The low spots will help oiling and not a concern.

          Buying old cams is a crap shoot. But having old followers and a fresh cam is not good either. You need good to excellent condition followers and a new cam. Get adjustable sprockets and degree the cam in.

          You will be happy when done.

            You could give a company called Cylinder Head Engineering in Fareham a ring. They do / did this sort of stuff but I haven't been down there for a few years now so don't know if they're still going. They used to have a website but that's now gone (which makes me think they may not still be there) but if you google the name the company details still pop up.

              that oil cooler is about as useful as pockets in underwear
              coolers reply on air flowing through them, the fins on that one have been flatted most likely by a high preasure washer

                You've got LCP right across the road from you, right next to the merc garage, take it in there and see what they say.

                Don't say can't, as anything is possible with time and effort, but, if you don't have time things get tougher and require more effort.

                  That clanking at 2:24 sounds more like normal clankshaft clanking when the carbs aren't dialled in right. Honestly, a bag of spanners sounds more melodious than any roller-bearing crank if it's out of tune.
                  From what I see, it's been a long time since the centre stand was on that (did it ever have one?) and it's quite possible that's a contributory factor - revving it up on the sidestand, at drunken off-base parties out in the boonies. Who knows what's been done to it...

                    Sound like a good excuse to sit with a couple of bottles of beer and a flat head screwdriver; straighten them out. Or Not, but the beer is still good idea.

                      Looks like there is some white glue or caulking in there as well. Beer is good but in this case, a whiskey might be called for.

                              Serious Metal Chunks Found in Sump

                              With the damage I have already seen to the top end of this motor, it was suggested that I remove the sump / oil pan and see what what is there. Shocking. But with a caveat. I have checked the clutch and pistons and they are all peachy (good). In fact the pistons are hardly scored at all.

                              I am thinking (praying) that this might be the residue of a previous engine failure. OR where else could these chunks have come from? We are talking serious bits of metal here:

                              (for the whole picture set see my blog here: GS1150 Metal Chunks)





                              The bigger pieces (aluminium):





                              Smaller pieces are steel:



                              All of the smaller pieces have this grooving on them:





                              Clutch and pistons are good:





                              Help!!!
