My fiancee has an '02 Sherpa we just picked up for her, and she loves it!
The one we've got, when it's warm (especially at low speed) revs the crap right out of itself when you stop.. No tach, but it idles high enough that she doesn't have to use the clutch (in first gear, at least).
Does this sound like a carb issue? Is the idle hand screw mucked up? Also, are there any online guides to carb stuff?
