Close Pitch Fin Pre Unit

Kinda Pricey but it's cool. I like the dual carb head:

1951 Triumph Pre Unit Alloy Trophy Motor - $1400 (Lake Oswego)

This is a rare Triumph pre unit motor with alloy cylinder barrels and head that was used on the Trophy models starting in 1951. This is the second generation alloy motor produced by Triumph and has the close finned head and barrel design for improved cooling. In addition to the Trophy, this engine was also used on the 1950's flat track racer (T100R) and the T100C model that used the famous Triumph Race Kit in the early '50's. This would also make a great vintage racer or café racer.
This motor will need new sleeves installed in the barrels as well as valve guides, valves, springs and keepers in the head. One fin at the bottom of the barrels has been repaired and will need to be trimmed and finished. All other fins on the head and barrels are in good condition. The exhaust port threads on the head are in excellent condition. Manifold tubes have been welded to the intake side of the head, which could be used as is or removed to put back in stock condition. This is an exc ellent core motor to use as a starting point to build a vintage motor for your old Triumph or other vintage bike. All the hard to find parts are here, including the BTH magneto.
