Funny thing is I own a sport and have never had any problems with the drive portion of the MB...... Ever. I've ordered parts from MB proper and from a couple different dealers and have always get awesome customer service, prompt delivery and quality replacement parts? But op you see the MB motors aren't made in La. There of course made in Utah. According to the professionals on this site no one can build a mud motor unless your from Louisiana. Because of course there isn't any mud in any other state.
I would say its nothing personal they love to hate on everyone the same, but I think some of them do have a personal vendetta against mb, the owner, the workers and anyone who owns, has owned or thought about buying one.
I'd put my MB sport against any similarly modded mm regardless of brand, any where, any terrain. It has been a beast of a frame and they almost all run the Briggs big block v twin. There are a few kohlers and Kawasaki motors out there. So don't read to much into the he man MB haters club. Ain't nothin but a thing chicken wing.
