02 exc400 engine issue

Recommended Posts

I just picked a beauty 02 400exc from a friend who hasn't run it in a long time.  I emptied the tank and put in fresh fuel.

So now, it runs, but it won't rev and it won't run without the choke on.

Is my carb gummed up?  Do I pull the jets, etc?

Ideas?

Thanks!

Take the carb off and clean it. Take all the jets out and clean them too. If it was sitting there is a good chance the carbs are gummed up. Keep us posted

Go buy yourself a new pilot and main, there cheap.  I don't clean them on bikes that have ethanol poison.
