Engine wont rev

I just picked up a 1987 Honda XL250R dualsport. The bike sat untouched for two years. The problem is the engine won't rev up and won't go past 30 MPH. The engine is a single cylinder with a dual carb set up. First thing I did was took out the jets, cleaned them very good with carb cleaner, and blew some air through to make sure they were cleaned out. Didn't work. I then took off the exhaust to make sure the wasn't a nest from any critters. It was clean. If you could help it would be appreciated.

Carbs

When you pulled the jets did you clean the rest of the carbs? There could be a secondary jet or port plugged or even the needle valve could be gummed up.
