    I'm very sorry to hear about this. Let us know if we can help in any way.

    One thought, if the head was sand/bead blasted and grit got into the oil galley passages it could cause all kinds of problems. Hope this isn't the case but wanted to mention.

    As far as the oil is concern, I wouldn't worry.

    Good luck

      hi

      well here we go

      i took off head and confirmed No1 and 4 valves stuck. I had to tap the valve in ,to then get a grip on the bucket to take it out.
      I then took out the valve. Although it now goes in and out, it is a little tight the last few mm so it must be bent?

      A friend has helped with this part, I asked him to check the valve timing procedure, although I thought I did it 100% right I'm doubting my self now, may it jumped a tooth when putting in the top guide in between the sprockets. I don't know

      See if this makes any sense to you. When you line up the exhaust shaft and it is in the correct position and inlet NOT [ out by 1 tooth] would it be the inlets valves that would hit the pistons and bend. Does this sound possible ??????

      So can i get away with just getting 2 new inlet valves and still get to the rally on friday

      where can i get them in the UK? [ kent ] tuesday 06sept WED ???

      HELP HELP

      WISH I HAD TAKEN SOME PICS BEFORE I TOOK CAMS OFF

        One tooth out on a GS1000 and they run - not very well but they don't bend valves. Having said that it sounds like those valves are bent. You're going to have to pull them out and have a look. Are you sure you weren't 2 teeth out (easy done)?

        As those 2 are the only stickers I'd guess it was just 2 bent inlets. And you're lucky where you are. Robinsons will have them surely - and you can nip down the road. You'll almost certainly need a new head gasket as well; you might be lucky - but it will be luck, otherwise.

        If you can get the thing up here I can give you a hand one evening - nothing else confirmed booked in. I'm boogered Friday as it's Netley (too late for you then anyway).

        Edit: just saw your other post. If you were only 1 tooth out and those valves jammed I would be seriously worried that you have had some left over grit that has got in there. It's a grade A b*stard if the head isn't 100% cleaned and they are bloody difficult to clean as you have the blind oilways (behind the rocker cover caps) that make the job a tad tricky. Have a feel of the oil in those valve pockets - any grittiness at all and that what's happened.

          Okay, just saw your other thread again...

          From photos in your other thread you had tons of blast media down into the oil galley passages on the head. I'll bet that's why those buckets stuck. The oil passage was cross drilled from the side of the head and then plugged by Suzuki so it's very difficult to clean out all that crap after it gets into the galley.

          If that were my bike I'd pull the head all the way apart again, and then consider drilling out the galley plug and then tap it for a threaded plug. With the plug out you can then make sure the passages are fully clean and don't have any blast media still inside.

          Of course I don't know for a fact what the real problem was, but I do know it's really hard to clean out those passages once the grit gets inside.

            contact debben performance www.debben.co.uk or give robinsons foundry a call.... speak to michelle http://www.robinsonsfoundry.co.uk/ - there's very little these folk don't know regarding the parts for these bikes....

            i hate, with a passion, blasting engines. chemically dipped is the safest way by far as it leaves zero behind.... sorry, i don't mean to sound harsh but that stuff is a nightmare to clean out of head and cases...

            good luck m8...

              I thought had got all those blast beads out now i'm not sure

              after nessim said ''maybe the dust go stuck around buckets'' i can see that as a strong possibilty because in run fine untill I got on the road the only good thing might mean i had set timming right ..lol


              there is plenty of oil going to the head seems clear no crap in it ?


              s**t why did i bother with the head coating

              not sure what to do now

              robinsons have no stock said 3/4 days,,where do they get there stock?

              will try debben tommorrow

              hampshirehog do you have your own breakers/shop or the like??


              thanks vic

                I've got loads of old bits but I'm sure I haven't got any 1000 valves. If it ran right on start up you will have had the timing ok (they run like pants if you're a tooth out - you would notice). So you need to pull those valves and check for straightness. You might not need them.

                If it is grit you have a problem. Have you got a pressure washer you can fire down all those oilways? I've just sorted an OIF Triumph for a guy that had been blasted and the washer worked. Soak it in water with added washing powder (Daz, Ariel etc) which breaks down the oil / surface tension etc first.

                  grit grit grit [chris at barneys bikes was right don't do head ]
                  now my eyes have been opened there's lots of it

                  o well at least i know the vavle timming was right
                  please make it clear how to clean out oil ways under cam journals and drilling out plug

                    You could start growing spuds in there. You have to get all that crap out and it is a bugger.

                    2 methods, neither 100% so no guarantees.

                    1. Blast the hell down the cam journal oilways with a high pressure washer - use the soak in washing powder trick. You might get lucky but you're guessing (you can't see an can only tell from the lack of grit coming out in your washings.

                    or

                    2. If you look sideways on at you head you will see 2 plugs at the end of where the cams run. These are where Suzuki drilled the oil ways and then blocked them off afterwards (they didn't have drill that went round corners). If you remove these plugs you will be straight in to the oil ways. Get the washer in there.

                    You'll have to drill the plugs out and either weld the hole back or you may be able to tap a thread and run short bolt in there.

                      I'd say either drill out the galley plugs and thread for pipe plugs, or soak the entire head in some solvent to degrease, followed by repeated flushing of the passages with high pressure water.

                      The cross drilled passages dump into the cam chain tunnel, so if you have push water in though the outer stud passages (you need to plug one end) then the water will come out the cam tunnel.

                      I did this exact thing when cleaning the head on my 1000. Got blasting grit into various places it shouldn't and then flushed it out with degreaser and water.

                      Here in the states they have a cleaner known as Simple Green. I flooded the passages with this stuff SEVERAL TIMES, followed by using bottle brushed down the passages in the cams (very small) and water, water, and more water. Took me at least two or three secessions before I was confident the passages were clean. It might be easier to just drill out those plugs.

                      BTW, I have loads of spare valves, but obviously, they won't get there by the end of the week. Let me know if I can help.

                        thanks hamlshiredog and nessismgood advice ,

                        is there a picture some where showing exact layout of oil ways ???

                        please confirm
                        i believe oil comes up 1 outer stud on both sides ,
                        then splits ..and all goes back down the cam chain tunnel
                        1 to feed the bottom of the bucket area and then [big passage ]
                        2 to feed where the cam journelsare under the caps [small passage ]

                        but on mine it looks like its just the big passage which is the easyer one to clean out ,or so i thought

                        my camshafts are still perfect no signs of grit

                          i believe robinsons get stock from the netherlands but could be wrong. pretty sure europes main suzuki distribution is done from there... 3-4 days isn't that bad new new parts on such an old bike tbh. debben is always good to try but may take a while to answer their phone ... or you could try the god of tuning in the uk, roger upperton http://www.uppertonracing.com/ , again, he may take a while to answer the phone but persist!.... best way to clean out that head imo is to get it ultrasonically cleaned and explain the issue with it.... the cleaner tank should be big enough to turn the head around, upside down, on it's end to get the media out.... horrible stuff

                            I don't recall the exact oil flow path but if you look close at the ends of the head, there are actually 8 different plugs pressed inside to close off oil passages that were drilled. The larger passages are to send oil from one cam bearing to the next, but I'd need to study the head to understand what the smaller passages do.

                            At any rate, good luck with getting the grit all cleaned out. It CAN be done. Soaking in a degreaser is critical because the grit will not flush out if it's all gooped up and stuck to the inside of the passages. Degrease really well, followed by lots of flushing. Ultrasonic will do nothing to flush the grit out but it may help degrease so do what you feel is best.

                              without wishing to start a contest on whats right or wrong but i've seen tanks that are clean to start, media blasted heads go in, and a layer of silt on the bottom when they're taken out.... that combimed with a cleaning agent will completely degrease and get rid of a huge portion of what's stuck in there.... the reason i mentioned turning it etc will also assist for obvious reasons...

                                Ultrasonic cleaning is a fine suggestion, however I believe it needs to be followed up by flushing of the passages because the grit isn't going to flow out by of those galley passages all by itself. Ultrasonic cleaning will have the added benefit of removing the grease without damaging the paint (I think).
