I have a rm 125 that i just got. It is a 1999 and the problem i´m having is that it won´t idle. Kicks over fine and revs out nice but as soon as you let go off the throttle it is like you hit the kill switch. I reached down and grabbed the throttle cable where it goes into the carb and pulled up on it a hair and i have twisted the throttle like a 1/16th of an inch. If i do either one of those things it will idle, so i´m thinking the idle needs adjusted. Can anyone help on how to do that? It has the keihin carb.....if i spelled that correctly. Desperately seeking an answer, the local shops are no help. Thank you for your time in advance. Bobby
