The Yamaha Jog ZR is RPM-limited by the CDI unit. This is a step-by-step English HOWTO on upgrading this unit on the 2006 ZR.

DISCLAIMER: All I have done here is write up the process in English for those who may not read Japanese or not read Japanese well enough to be convenient. If you follow my directions and break your scooter, I assume no responsibility whatsoever. When modifying a motor vehicle, keep in mind that you are doing so of your own volition and any problems you have are your own.
