I don't think it has an adjustment.A thicker bodied oil might inject at a lesser rate,so try that.
Some folks just disconnect the oil pump and pre-mix all their fuel at 32;1.
I don't know how to disconnect the oil line,but a search would turn that info. up for you.Hit `cached' when you get the results you want to view.
Also,on www.mopedarmy.com you can holler for `Jax',and he knows quite a bit about the Express. Also www.mopedriders.com don-ohio
