    Sounds a tad rich, when fully warm, the bike requires less gas than when its "cold"

    An exaggerated example is the choke system needed for cold starts.

    How do you kow "exact" temp? Is that based on the water temperature, cause thats not stable througout the entire system, becuse of the thermostat.

      @jens-eskildsen That's wrong.

      A choke restricts the air, raising the fuel air mixture. Like if you choke a person, you're restricting the air. It's different from smothering them though...ask my ex 😞

      "A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine. Depending on engine design and application, the valve can be activated manually by the operator of the engine (via a lever or pull handle) or automatically by a temperature-sensitive mechanism called an autochoke."

      Taken from our reliable friends Wikipedia

        Norwp, what I wrote is pretty correct

        Can we please agree that the fuel to air ratio is lower with the choke opened? You cant make a could engine start at stoich, as you dont get a "clean" burn. Weather this is acomplished by restricting air, or fuel is added is not important in this case, you still accomplish the same thing, LOWER air/fuel ratio. And I didnt even mention it to avoid confusing the bloke. Its different from bike to bike which way the choke works.

        You seem to be confused about the ratio, Its and Air/fuel mixture, not fuel air mixture. Yout got it backwards.
        Raising this mixture is making it leaner, as the majority of the parts are air. So if you raise that part, you make it leaner. Google it if you want. Just edit your post when youre done, so youre not confusing others.

          To clairy, I didnt in anyway explain how the choke works, so I dont know why you quote Wiki on that.

          I just commented that a cold bike needs more fuel to run effecient, compared to a warm one. This is because the fuel doenst atomize perfectly when cold. Again, weather this is done by restricitng air, or adding fuel doesnt matter, the result is the same. And I didnt write anything about which way our choke works..

            @jens-eskildsen Yeah you're spot on bud. It's where you said needs less gas. The Americans use that word to indicate fuel.

            I think the bike is running rich on the top end.

                @irongamer727 Fck sake, you're not the first to say that.

                I do apologise, it's always hard to get the tone across in text. I'm being sincere, believe it or not.

                I don't have all the answers, I think discussion is a great way to get to the answers. That's all.

                              Have a look at this. Bike is missing power at WOT. There's also a substantial amount of oil here. Seems to have leaked past the o rings.

                                        @irongamer727 Looks like exhaust gases are leaking past the rubber oring from the bush.

                                        That are the bush is excessively worn and needs replacing.
