My Ninja 250 (don't knock it till you try it), won't idle without the choke on at least part way (after warmup). There is a definate flat spot through the low RPM range, but once you break through it, the bike winds out well. It has been this way since it rolled out of the shed after winter. I have some sea foam carb cleaner in the tank, and while I have not been riding it a lot, things have not really improved. Idle jet clog?
Thanks. |

Just to add to what others have said, the idle jets on these carbs are very small and can be very challenging to clean.
This brings back bad memories of a Honda Rebel 250 that this girl brought in to the British bike shop where I worked for while. Took me three tries cleaning out the stupid carb before it ran right. Never had trouble like that with an Amal. Spraying carb cleaner and shop air may not do it. I ended up using a strand of soft copper wire to clean the jet. Hope this helps. |
