  • rz250r choking

    ok so i have looked around for info and found stuff all, the problem is my bike acts like it choking when i start it and even if i can get her walm its the same its hard to get any revs out of her, cant figure out whats wrong only thing new is the throttle cables,
    Also does not sound the same like its firing on the right cylinder as often as the left side, plugs are new plenty of spark coil tested, good.

        umm shouldnt be compression

        but its easy to check at the same time as you are messing with plugs, sometimes things go wrong after you have had motors apart :p

        apart from compression:

        are powervalves actuating together? pull both covers off and turn one side with a shifter to make sure both pots turn as one.

        carbs balanced? zero position identical on both pots tuned with the idle screws? WOT position identical tuned with cables?

        jetting wont have changed

          i was thinking carbs balanced but as i have a hard time finding a manual i have no luck getting anywhere,

          how do i tell zero position in both pots?? if you mean both are fully closed yes they are,

          and can you tell me what the WOT means? on a limb here, wide open throttle??? lol

          o PV's are fine

              so the idle screw sets the closed throttle position of the slides- it should be exactly the same in each cylinder.

              if you let the thottle close, you will easily hear the slides clunk on the stop. there should only be one clunk.

              there are sight glasses for WOT, you adjust WOT using the cable adjusters.
