I have a 2002 DRZ 400S with 4300 miles. It has a yosh RS2 and the 3x3 mod jetted per this sites specs. Bike starts and runs ok but after warming up it shuts off at idle. I started to troubleshoot using the Factory manual and when checking the Ignition Coil the manual said to use a Peak Voltage Adapter. What is a Peak Voltage Adapter? Any suggestions on what to check for the idle problem.
Thanks!!
