Triumph 650 to 750 Big Bore Kit
$725.00
This is a 1963 -1972 Triumph Unit 650 to 750 CC Big Bore Kit. These will fit a 1950-62 Pre Unit engine with the use of a later model 9 bolt Cylinder head (1963 and later). This Kit is set up not to use the factory Oiling system for the exhaust lifters. Many big bore kits didn’t ever use them. We can provide a plug for the hole on the engine case if requested.
