DAD, I for one do not agree, as one who has "butchered" a lot of these engines, there is no problem with the castings, and I make castings for the Yamaha 600R, to allow direct change over for the oil, fuel, ignition, and the connections for the drive line, from the Honda directly to the Yamaha. I spent a lot of time making this changeover as painless as possible, but it does require some knowledge of working on engines, I really think you're betting on the wrong horse, the TQ was here long before the Mini, and "Tradition" will help carry it onward.
