    GS500E rebuild, 1989 style

    Thank you, can I get a forum badge for that? :D Indeed, there's still time in this day, I might post more!

    GS500E rebuild, 1989 style

    Back to Woodcutter's engine. It's very clear this engine has a lot higher mileage to it, this chain guide will have to be replaced. Also this balancer bearing ain't fresh anymore. And just like bandit's engine, I will be removing the valves. Most definitely these were leaking a bit...

    GS500E rebuild, 1989 style

    As I said earlier, the Katana front wheels require spacers to make the narrow wheel work inside the wide USD front forks. It took some effort but I have acquired all necessary information to be able to draw up these spaces in FreeCAD. ParameterKatana (GSX600F/750F)GSX-R750 K1GSX-R750 SRAD...

    GS500E rebuild, 1989 style

    Let's start on Woodcutter's engine: Nasty bussiness. Two broken exhaust bolts...great... Loads of sawdust all over. There's a weird pink color on the valves. And, after an hour or 2, this is the result: To be continued.

    GS500E rebuild, 1989 style

    And we continue. I've started on the head, removing the valves. It's all quite nasty. this will require some cleaning later on. Removing valves one by one. Et voila: A valve only its mother can love. This valve, even its mother...anyway, you'll get the drift: That's it for...

    GS500E rebuild, 1989 style

    Now, as these bikes are stripped to their last bolt already, and stored in boxes, there are no interesting photos to be made of the state they are in, so I'll start with details. I've been disassembling the engines to prep them for paint, and to get a feel for the state of the engines (need to...

    GS500E rebuild, 1989 style

    Hi guys, I've been working on 2 GS500e's that I am building up to be the best looking GS500e's out there (in my opinion;)). I've been keeping track of the progress on a forum in my native tongue but I figured I'd start a thread here as well. You might remember me from the GS400/500 GR650...

    GS400/500 Gr650 Hybrid engine

    Very nicely done! I don't even consider it "build", it's purely for looks. This GS500E is gonna be a fun backroad bike, nothing serious about it. But I understand your sentiment, to be honest, the whole thing was an experiment, I wanted to see what this idea would look like. I have run into...

    GS400/500 Gr650 Hybrid engine

    A small update on the GS500 guys, mostly as a proof that I'm still alive and working on this, and as a distraction from the fact that NOTHING has happened with the hybrid engine of late. I promise, progress will be made this year, I just want to get this GS500 out of the way first :). I did a...

    Thats a good plan, Can I follow your progress somewhere?

    GS400/500 Gr650 Hybrid engine

    True, but that issue is mitigated with custom pistons. Hence, why I said "if you are going to source custom pistons". I take it, "custom pistons" means having them made by CP Carillo or equivalent.

    GS400/500 Gr650 Hybrid engine

    Welcome! The stock GS500e pistons should fit that motor, or do you plan to increase C/R ratio as well with custom pistons? It's a real PITA that the exhaust exit angle is different on the GS500 heads, otherwise you could have used those. If you are going to source custom pistons, might as well...

    GS400/500 Gr650 Hybrid engine

    Small update. I received the parts I ordered. I got SKF IR 28x32x20 bearing races, they will have to be modified. Two oil feed holes will need to be drilled, as shown in the drawing below. It's hard to measure accurately but they should be spaced 88 degrees apart from each other. Diameter of...

    GS400/500 Gr650 Hybrid engine

    The stud spacing has already been modified on the crankcase Chuck!, maybe one day I'll restore all the photo's in this topic but for now take my word for it. It involves machining aluminium plugs that are screwed into the stud holes using the strongest epoxy glue one can find and then...

    GS400/500 Gr650 Hybrid engine

    Progress! During the last couple of days I took the time to create some tools to press both the GS400 crankshaft and the GS1000 crankshaft apart. I made some exciting discoveries. See the drawings below for what you need to make to press it apart. And here is the final product with the...

    1981 Suzuki GS650G - dies under load when throttled past ~1/3

    Your remarks regarding the weird pilot screw, replaced screws, possibly replaced boots makes me think chances are high the PO has messed up a carb rebuild. I still think you should start with a proper compression test and then move on to a full carb rebuild. stop messing about and do it once...

    GS400/500 Gr650 Hybrid engine

    I have looked through multiple catalogues to find fitting rods for the GS400 crank, no luck. I also have a preference to use OEM Suzuki parts, hence the GS1000 rods. I managed to find a GS1000 crank for about 110 euros, which will yield me 4 rods, 6 bearings, 8 rod washers. Figuring it's not...

    Valve shimming and tuning (GS450E)

    Good stuff, have you managed to put the bike together in the meantime? I'm based in the Netherlands and have a lot of shims on hand, postage within Europe is just 15 euros I believe. About the popping...do you have stock airbox installed? The OEM CV carbs do not work well with pod filters and...

    1981 Suzuki GS650G - dies under load when throttled past ~1/3

    You've done a great job troubleshooting the issue so far. Assuming the ignition is really alright, I'd say do a compression check first before you spend hours and hours fixing the carbs. Do a test in cold and warm condition. If compression tests OK then I'd say there is something wrong with...
