Dan,
Be careful man. Jetting and lubrication are two different things.
I know nothing specific about the injection sytem on that bike, but I do know it is hard to tell wether you are heavy on oil or just running rich carburator wise.
I would look at the plug and if possible the piston. You should see a little grey/brown on the ceramic insulator. If the plug has a chunks or a layer of carbon on it then it may be your oil, but I would start with your carb.
You might just re-pack your exhaust and tell the little one to rev it higher, most 2 smokes like to hang out in mid to high RPM ranges, if she's running it at low R's it's gonna load up no mater what.
