I have high idle on my 03 mxzx 800. I have done everything besides the slides(jets, adjustment screws, idle adjustment, crank seals, boots, etc). Which leads me to the carb slides. What causes the high idle with these?
Is it the groves allowing air thru?
Is it the worn surface causing them to hang up?
I purchased a used set hoping they would be better, but they are not. These are pretty worn down, I can feel the missing material on all slide. I know coating is an option, but I would probably need better shape slides. Can I just sand the face down flush, then coat? Any at-home coatings I can apply? There has to be a better solution to high idle.
