Hmmm really? well i'll be sure to tell Rob & nic that there 7bolts that make over 700 ponies that they are bad motors. :lol:
THe main advantage is the 6 bolt has larger crank gernals but doesn't have oil squirters for the gudgens, where the 7 bolt does.
People will waffle about "crank walk" which technically is thrust bearing failure, but if you start talking to some of the guys in japan where these things are made, most are using 7 bolts
