Kibblewhite Tappet Blocks 1969 - 1983 for Triumph 650 / 750 Twins • Precision ground OD and reamed bores allow for easy installation exceeding OEM tolerances. Cast iron tappet blocks are machined from a proprietary cast iron material with the same design features as our bronze version, providing a more affordable alternative.

NOTE: Bores are sized with a piloted reamer and finished with a ball hone to achieve proper running clearance and surface finish AFTER the tappet block is installed
