Well I took the plunge and took a drive today in the rebuilt classic... 200 miles or so later and I can definitely say she's running like a top - the new motor pulls like a train and even handles highway speeds with aplomb. Kudos to Seven Ent. for their rebuild skills. I'm leaking oil from somewhere... the exhaust is actually pretty oily, like I'm leaking from the back side somewhere (of course... someplace I can't see or reach without pulling off the carbs... again). Other than that, just some electricals to re-hook and I'm 100% I think!!
