Cynth wrote Tony at TravelScoot, telling him her throttle isn't as responsive as it used to be and asked for instructions on lubricating it. This is his response:
You can try applying Vaseline at the rotating grip of the throttle and see if that helps. If that doesn't work you try a spray lubricant, preferably NOT WD40 to the area. Let me know what works.
Best regards and Happy Thanksgiving,
