Did a search first to see what I could find out about my throttle stick. This is what it got me. Mine is definitely a water issue of some sort. When I go through water or wash it, it sticks. I'm wondering if there is anything I can do to avoid the stick besides the obvious, don't go through water and don't wash it???? It has had two new Motion Pro throttle cables put on. The slides are perfect. Nothing else in the carbs has any sticky or rough spots. Shee just doesn't like water. I have learned to tippy toe through water, but is there anything I can cover or protect when washing to avoid the stick? Thanks for any help.
