He doesn't say what needle he has.... If it is the n1ef, then your suggestions will definitely help... but to fix it he needs a better needle along with something like a 42 pilot... back out his idle screw when switching to new needle etc.
As a side note, The MC comes with a higher compression head so it might not have as bad a squish measurement as the ec model. Jeff

older bikes do wear the jet nozzle out and make the jetting really tough and different from what you have heard are the standards. I had a few lively discussions with webmaster about a 01 ec 300 that i had years ago. the bike had probably close to 1000 hr's on it, the inside of the carb was trashed, and i had to go super low on the jets to compensate for the fuel going past the needle when it was in the jet nozzle at low throttle positions. One more thing,that my buddy's and i discovered and used with great success was to go from a #7 slide to a #9. way more air getting through at low openings,made everything work much better in the idling and low throttle opening circuits. good luck !

I was aware of the oval needel tube, and it looked round, emphasis on looked. I'm running the N3CJ needel, yes stock is realy bad. The running at 1/2 half throtle is good and the cable is with a bit of slack, it slams the throtle body. And the idel screw lifts the throtle body as it should. The idel is just to low other wise it runs great, well except from some spool but that i can live with, it is a 2 stroke after all.

I had the same problem with same needle.
Dropping the pilot tot 40/42 and dropping the needle two positions helpt for me. And the airscrew is important. Your bike will not idle properly when it is turnend in too much. |

I've had the same thing happen on my 2010 model back in the day. Single petal decided to break down on a corner. Replaced them and no issues since.
