Hey I am pretty new to this and my 03 660R will idle a little slow and die sometimes, I will try to adjust the idle just a little and the motor will idle right for a few moments and then rev up quite a bit. I will slow it down by adjusting again but then its to slow and dies. Sometimes when it revs up I can put it in gear a let out on clutch and motor will idle right for a few moments then it will rev again. This is driving me nuts any advice will be greatly appreaciated.

 

Check your throttle cable and make sure its not loose.

Also make sure that the screw and clip holding the top of your throttle control is there.

 

the wires under the seat [at the plug were the bat.+post are] clean .and see if that helps.had to do it to mine [02] and buddys [03] ....... use some DI-ELECTRIC GREASE on them.
