    flat side carbs?

    Those look like stock VM26 carbs. are they known as flat side carbs? I though the BST slingshot CV carbs were also called flat side carbs (flat slide?)

    Well, it's very neatly done, and a useful redo of an L model.
    I look for performance improvements, not so much pretty polishy stuff.
    I see some performance things, I like the top end rebuild, and the flatside carbs!
    The L forks…meh.
    I like the gauge change.
    Is that a Bridgestone Spitfire front tire? Really scary bad grip from those, had them on 2 bikes I bought.
    That green looks like a nice color for a bathroom, kinda fem.
    Sorry, I only like some of it.

      The VM carbs were the first called flat side carbs, they are not CV type carbs. The BST carbs have a flat sided piston and are CV type.

        Thanks Bill, so they are the stock vm26 carbs with pod intakes, and a 4:1 header to open pipe? Might the builder share jetting? I rejected my 79 gs1000e with 20 pilots and 130 mikuni mains (stock jet needle) to run with knock off k&n oval pods and 4:1 pipe going to an open "muffler" I made with 3" pipe and an internal antireversion cone.. She runs pretty good but touchy around 4k and at a constant throttle above that (like she just wants me to open it up and she does pull right off if I do)... And not to steal the OP thread, but I do have a set of bst32 or bst33 from a katana600 I was thinking of trying on the '79 gs1000, anyone have luck with that?

          You need to start a new thread about your jetting issues in the carb tuning section. I am not a carb tuner. A lot of tweaking issues come up with pod mods, because you're discarding tuning for public road conditions and tuning for WOT race performance. You can't have both.

            Thanks Bill, but my post was directed towards the OP Imari who is running a set up very similar to mine. And btw, I wouldn't call pods and pipes wide open race configuration. I've had bikes and seen plenty of bikes run fine on the road like that.

              I like fenders & a bit more seat, but that is a very nice piece of work. Seeing what you started with, I go

                Not bad at all. At least you have a full exhaust instead of the stock head pipes chopped off.

                  That is a fantastic job Imari! Should be huge inspiration to anyone restoring or modifying a bike. Way to stick with it and you should be proud of that work of art.

                    What tail light is that? I'm trying to find one that fits in the top, inside, of the tail piece opening but not too high in thickness. I'd like to find one that is roughly an 1" to an 1 1/2" in height with acceptable brightness....and the one you used is very close to what I'd want.

                      Really liking how your build turned out! Is it safe to assume you took some inspiration from Luke Robinson's build for this? The battery is hidden way better than I thought it would where you have; I was teetering back and forth on Brat vs Cafe for my seating options but out of fear for the clean look, I opted for a cafe style seat.

                      The Tail light and turn signals are really nice, where did you pick those up at? Do you have a link by any chance?

                        Nice work. I usually avoid the cafe/brat threads because I like the original unmolested look best. However I think my view is somewhat encouraged by the embarrassing hack jobs (pieces chopped off a good design and what's left fogged with a flat black rattle can) that get presented as something special.

                        Your hard work, attention to detail, and even color choice set your bike apart from those that make me shake my head. Color is especially subjective. I like vivid reds and blues (and pearl--lots of pearl), so I wouldn't think of using olive--however, it does go very well with the seat color and with most of the rest of the bike blacked out, the result is very nice. I appreciate your art.
