I would put something on that will give you about 10 - 11 thousand RPM at full throttle and see if it works out.
2-strks like to be run in the higher RPM range as this is where they make their power. 4-strks don't like to be run over 10k as they make their power at a lower RPM.
I also recommend the APC 15x6~8 or a 16x6 if it can spin it.
