    Throttle response very touchy

    Never thought I'd say that my bike is running too well. OK, I've got about 60 miles on her since the carb rebuild and the valves reshimmed. Power difference is amazing. This is going to sound strange, but now the bike seems to have too much power too soon into the throttle. The bike idles fine, runs fine and has no flat spots straight through to 9k in any gear (1st through 4th is all I had the balls to do). Only a slight turn of the wrist and I'm off and pulling strong. Just seems to come on a little too fast for my liking. Almost like it has a faster cable pull then normal. At a steady 60mph in 5th gear, it only takes maybe a 1/4" turn of the wrist from off throttle to maintain it. Is this just my perception after riding it when it was so out of tune to now it running correctly? Compression has jumped from 130 to 150 across the board as well.

    Darn, with so many daily riders it's hard to decide which one to jump on next.;)

    Welcome to the world of a properly-running 850.

    While you are enjoying that, though, keep in mind that the 850 is probably the slowest-accelerating four-cylinder GS.

    If you pay attention, it also has a dual-range powerband.
    Smooth and docile up to 6k, but take it over that, it's like somebody added a small shot of nitrous or grafted on a fifth cylinder.

      My previous bike didn't seem to be so off/on/off as this one and it was a 79 GS1000L so I was a little surprised at this from an 850. Maybe it's the shaft drive that I'm feeling as well.

        I used magic washers when I shimmed your needles.

              You may want to check where on the throttle grip the cable is connected. I noticed on my 450 that there were two connection points for the cable end pin.
