I had XPR build this engine all the way from the ground up. Starting with a completely new crank that was built with a Carrillo rod and topped with one of their custom hi-comp piston. XPR used a brand new head to do their port work and install their custom valves and valve springs. XPR installed a new custom cam. The engine was completely torn down and the transmission was given their works treatment - full disassembly with a tumble and polish. Then there is a full Hinson clutch system. Boursin water pump. Then the side cover had the oil sight glass deleted professionally and then cerakoted. The valve cover was also painted red. (Please note that the cerakote has wear from use- especially the stator cover due to boot wear.) This is a beast of an engine with around 8 hours of use. I’m a vet rider so these are not hours on the rev limit in racing.
