I would totally agree with you on that. And the fact that the nz series engines available in the market nowadays are much lesser used than the efes and much more complete too and their parts are easily available, expensive, yes, but easily available. And since the technology is newer, they're more durable aswell and they're easier to troubleshoot aswell. Nz is alot lighter than the efes too so they're not too hard on the suspension aswell.
