Posted this on the 12-17 side too with little action on it.
Is itpossible to run the team roller primary with the older cat secondary on a 2015 m8000? Assuming the 111 belt is also required or will there be an alignment issue?
It has been done, but is not optimal. Deflection is a problem. If you have a 2012-2016 the easiest option is to do a Team Tied secondary that bolts right up. Either way, the 111 belt is required.
