My banshee runs very well when the engine temperature is cold, but after 10-15 minutes of hard riding it starts to run bad. By running bad I mean that it has trouble getting into the powerband. Once it gets there, it runs ok but not like it did when it was cold. Always starts great.......have to choke it when the engine and weather are cold and crack the throttle a tiny bit to start it after riding for a while. The engine is new and has never been dialed in just right, so I was looking for some direction for my next jetting change. Its a ported 4 mill with 34mm PJ carbs and Toomey T5s. Everyone with a similar setup has far different jetting from person to person, so I am not looking for a jet size but more a direction to lean torwards (rich, lean, main, pilot and so forth). If I could make it run just like it does with cold engine temps it would be perfect. Thanks in advance.
