Moving the wing forward would exacerbate the problem.  The aerodynamic fix 
would be to move the wings 2-inches aft from the KR-2 plans callout.  That 
is essentially what was done with the KR-2S.  In the case of my already 
built (and flying) KR-2, moving the wings would amount to building another 
fuselage and stub wings.  I chose bolting on some steel weights.  Granted 
not the most elegant solution.  As Larry recommends, perhaps a bigger engine 
installation would indeed be the best choice.  Anyone interested in a 
firewall forward package for a Great Plains 2180 VW, Diehl case, Zenith 
carb, RR engine mount with 2" extension blocks, Sterba 52x52 prop, Revmaster 
oil cooler, Grand Rapids engine monitor with all probes and 10.6 engine 
operating hours, turning 3150 RPM static WOT.

I'm no aerodynamicist but seems to me the proper way to fix this problem
is simply to move the wings forward.  Either that or shorten the tail.

Using hydrogen or helium instead of air in the tires will help with
buoyancy, which might help.  This has the side benefit of increasing the
service ceiling.

Keep in mind when playing around with lead that it is highly toxic.  It's
against the law to use lead even for wheel weights, at least in
California.  If your plane is loaded with lead it's possible you'll be
stopped at the state line and have to take a bus the rest of the way.
Lots to consider here.
