        The cam's were painted. This is after a few revolutions *even with plenty of assembly lube*
        I wiped it off just to take the pic, No way I would I ever rotate these brand new cam's without lube
        looks dry but blame my camera and poor lighting.

        I hope the starter can handle the new cam's and springs.

          That is a sweet engine build.I'd like to do a big bore and 4v head on my GS500E when I do FI.I'm still researching what larger pistons and cylinders I can use in my engine case.may have to open up the case a little.FYI,I think the 06+ crankshaft is an upgrade.If I ever do build a big bore engine for my bike is getting the full balance and blueprint job.I have a local MC shop that will do any work I want done,if I got the $$$.I could see me spending $1000 on a big bore engine.

            It doesn't take long to add up!

            And then there are all the little details that pop up.

            There's so many things to compensate for !

            Whats up with the crank? I didn't know there was an update!


            1000, ha thats a start :P I've lost count, I just want to wrap it up at this point.

            think 2-350 for pistons.
            same for cam's
            then head work
            gaskets
            tweaking
            tooling
            valves
            machining

            Its a long process with allot of for-thought needed



            The stock 500 jug can go up to 77mm with 2.5mm left to make it a 527, But that's max. Next is to get a 1266 or 13... sleeves and have your block bored to fit them. Then you can go to 82mm and be at 600cc's.

              Man even though I have no idea about any of this stuff... it makes me drool

              That thing oughta be a real beast once it's together!

              Maybe pre-empt the starter issue and give it a rebuild with fresh brushes now and clean up the commutator?

                Good info.What 1266 or 13?That confused me.Thanks.

                Dgyver on GSTwins did a 78mm bore on one of his race engines.He sold the bike and don't know if it held together.It had a couple runs on it.The cylinders were paper thin.I saw that engine.He was running flat slide carbs on it I think.

                  1266 or 1327cc engine's have larger sleeves installed because the original sleeves would be too thin.

                  Those sleeves can also be used in our 4-500 blocks if we bore them out the same way the guys with 1100's do.


                  I saw that post a while back, never herd anymore of it though. FCR 37's are what Ray recommended for my build. I'm looking but for now I'm sticking with the CV's.

                    I'm looking for a good source for brushes. Got any ideas?

                      An automotive electrical supply house should have something in the right size, or at least close enough to work.

                        Should be able to get them from http://www.oldbikebarn.com/ or http://www.partsnmore.com/ .You could try a local auto electric rebuilding shop.Something may cross reference with another make/model.

                          Thinking about just brushes and shave them down to what I need.

                          Is anyone making a brushless starter ? Like the type used in RC car's.

                            The DynA knockoff rev limiter showed up today. Looks ok, obvious to me now how its different. Also under the cover everything is potted Except for 3 wires going in and out of the epoxy.
                            I measured them and they are going to the 1 k pot that you set the limit on.

                            The min is 6000 and max is 12000, very simple wiring. So I was going to set it up with either a remote dial or set it up with a second dial and a relay for a two step limiter.

                            Maybe trigger it with the clutch switch. Or maybe a low limit for low gears and higher limit for higher gears.

                            Just thinking aloud.

                              Here's the first video, Not of it running yet but of actual work being done.

                              Valve recess cut via cnc.

                              Turn volume down at 0:50s !


                              Also ran into a bit of a snag. The cam's were ordered to be .355. Well they are definitly not, they are actually .370 !!

                              Oh well, a little more lift cant hurt
                              Just need to do some more calculations and check gaps, valve travel, any binding issues that sort of thing

                                And some pics

                                New valve relief's. Only 0.030 deeper than it was but now that the program is written its easy to tweak it for what ever depth is needed


                                New APE tensioner and head gasket



                                Ground rocker oil bumps





                                Hey how do you make images smaller when they come from photobucket ?
