    Where do our GSs make the most power?

    More or less in the RPM range, whats the "sweet spot"? Im trying to tune my sprocket set for this 530 conversion on the cafe, and it would kinda help to know. I'm guessing around 5500-6500 RPM. But this is based on where it feels most powerfull on my 1100G. This would be for a 77 750. Thanks guys!

      WEEEEEE!!!! is right, but just because that's where it makes the most power, is not necessarily where you want to run it all the time.

      Just for more relaxed operation, better fuel mileage, lower noise, whatever else you want to throw in there, you might want to consider making that rpm range available with a downshift. 8-[

          Right I dont want to hit the ton at redline. But i want the grunt off the line too. SO im kinda toying with this here.

            I run two over stock on the rear and I like it. Better off the line and doesn't red-line at 80.

              Well unfortunately, i have to play a bit of tiddly winks with the sizes, I got the damn thing (the bike) out of the basement today, got the motor in it, and put the 530 sprockets on. Ran into a snag. With the 1100 swinger conversion, the 14/43 i have wont let the chain clear the front of the swingarm. So i need AT LEAST a 16/45, but im worried bout the off the line power. Here, based on our gear ratios, is what that would work out to.

                I don't know what kind of mods you've done, but my bike really starts to pull around 6000 RPM. I'm afraid if I look at your work log I might see something that I like.

                  On a 750 the power comes in at a higher RPM than the liter bikes, starting at around 5,500, maybe around 7,000-9,000 it's the strongest.

                    If you want to keep the ratios, just add teeth to the rear to get whatever ratio you want. Use the biggest front sprocket you can, if a 17T will fit, go with that. To keep your 14/43 ratio, use a 49T rear with the 16T front or a 52T rear with the 17T front. They are not exact, but as close as you can get.

                      Well the 14/43 ratio was a lil large. But i wasnt really minding that since this bike will no longer be a main rider. SO..the more guts the better...heheh
