Will, here's a handy link to show you exactly how a variator works & what it does............ http://www.teamcalamari.com/zumasrus/zdox/ztip4.html ..... Some good tips on the website as well explaining about two strokes & tuning. Sorry Ray for butting in on your post.

a variator is a pulley that opens and closes (variable) lifting and lowering the speed (like gears) .take engine side casing off.you will see 2 pulleys with a drive belt fitted.the front pulley is the variator. the back half of this pulley holds the variator rollers.
