get the bigbore, shave the cylinder fins to clear the pump... even better shavethe fins AND run the pump back on itself (plug the line at the empty oli tank) and just use premix in the gas (the pump will give out eventually- all nc50's do), and that kit demands better lube than the stock so the premix is the safest bet to avoid a seizure... if yu are gonna run the bigbore, check the older forum and wiki posts for a custom intake and carb setup to really feed that bigbore some better breathing
