Default 98 CR250 Idle

     

So my bike wasn't idling. I had to adjust the idle almost all the way down. Now, to choke it the rod only moves up about 1cm. With this setting, it idles perfectly. It does still have the "click" when the choke is on. Is this ok?

Yeah that's what I figured. I was just a little scared at how close the choke setting is to the run setting.

make sure you have learned to go downhill with the clutch in or the transmission in neutral, ie dont coast dowhill in gear. it tends to foul plugs.

once that particular caburetor gets some age on it, the socket that the choke plunger rides up and down in wears. they all do, but in the case of this carburetor that choke plunger acts as a seperate slide to control the idle. when you get small leaks and vacuum losses around it, it acts up. it is just cast aluminum to start with, afterall. then you get strange affects like you are talking about. make sure there your float level is set right (16mm is standard and it will moved from day one).

If your serious about keeping your bike for a while and the pocket book allows, a different carb would be good....not many are a fan of the enricher being mixed with the pilot circuit....

It's combining it (enrichenor) with the idle circuit that bugs me. If you think about it, most all of them combine the enrichening device with the polonium circuit.

Yeah, I've been reading that. What carb do people recommend? What does it typically cost? I would entertain the idea of a new carb, since the motor is completely rebuilt, along with the suspension.
