I have to eat my words regarding that aforementioned decision to go with a big single. This deal was too good to pass, so I'll be hanging twin 150 Optimax. We won't be racing any big new super-CC's, but we won't get left in the dust too often.
Got them home and laid in the garage. Gotta get them up on stands today and order a lifting ring or find a universal puller kit that has the right size flywheel threads.
