Hello everyone. this is my first post here. i need some input because im at a loss on this one. i generally do basic repair to my bike. after cleaning the carbs with carb cleaner, spraying out all the little holes here n there going thru 2 cans of carb cleaner just to make certain all is cleaned well. and adding 4 new low jets. the bike starts real easy, however its idling at 4500 rpms. and i turn the idle knob thats in between #2 an #4 carbs to lower the idle but it has no effect on the idle. any suggestions?
