250ex starts right up and idles fine but I can't seem to rev much past idle at all or it dies completely. I'm gong to take the carb off and clean it and check to make sure a jet didn't come loose or clog with something. This has happened a couple of times before but it would go away after idling for a bit. I haven't looked at the spark plug but I would think that it wouldn't start at all if there was a problem there.

I noticed it has an inline fuel filter so it's possible it is partly clogged...does the 250 have a screen in the petcock like the 300ex?

Any ideas? Anything else I should check?

On reserve??? I'll check that out but I don't see why it would be any different than the "on" position.

Any other ideas?

I would suspect a clogged carb or fuel filter. or just plain low on gas.

Turns out the pilot and main jets were BOTH clogged.:eek2: Cleaned out the carb and it's good as new now. Not sure if I got some bad gas or what? I would think any dirt in the fuel wouldn't make it past the fuel filter though. I checked the air filter and it's clean and tight and all the connections from the airbox to the carb are all tight so I'm hoping it will be fine now. Thanks for the input guys.
