Re: How come we're not seeing MBs with motors like these?
I just read a thread, where a guy rode all the across. SoCal on a China girl, with no problems from his motor. I've got hundreds of miles on both of mine and I've never had the motors leave me. Part of the reason I'm into these is because they are so cheap and they present a build challenge. Machining things to precision tolerances stateside is not cheap buddy. I've got two sports cars and a diesel pickup if I want dead reliable.
You can get a lesser powered Morini as others have said, I don't understand why you haven't bought one yet?
