Hey DR guys. I usually hang out over on the Honda XR650l side of the fence but my buddy has asked me to look at his buds DR650. Looks like a late 90's model. Yellow fork boots and blue/purple frame.

The engine will start and idle but will not take throttle. Once the throttle is twisted some it will rev a bit and then fall on it's face, not accepting throttle. It's my guess that the diaphram in the carb is bad or leaking and not allowing vacuum to lift the slide.

What say you DR guru's?
