Maybe,.. maybe not. There have been numerous manufacturers of air cooled engines (not specifically RC engines) try fuel injection before, The issue is generally the combination of wide fluctuations in engine temperature and fuel injection, this combination can be quite problematic. This may be one reason for the 32:1 oil mix ratio in the listed specs.

Edit:

AH! I posted too soon, I see they decided not to bring the fuel injection part of it to market, I'll bet real money they had the same problems with engine temp/fuel injection that other air cooled engine manufacturers have had in the past.
