Running Lean?

Ok so I jetted this thing back to stock jets 60/83 and now it seems to stumble a little bit and hestitate in different spots between 1000-3000 rpm. Also it smells like its running WAY rich which it didn't with the larger jets in it. Weird I know, lol. Its also suckin gas like crazy with the smaller jets. Gonna go middle ground with the jets and see what it does.
