The JB-POWER Complete Engine is a fully reviewed and redesigned version of an old engine and is not limited to merely replacing consumables or defective parts, but also includes many improved parts, tuning, and enhancements. BITO R&D implements various improvements such as port polishing, valve seat cutting, big valve, and reinforced valve spring installation, transmission dog undercut, full crankshaft overhaul (bearing replacement, pin welding, rebalancing) as well as WPC friction reduction treatment or reinforced can chain tensioner to create a torque, powerful and comfortable engine. Also, it naturally depends on the way of usage, we ensured a high durability level that is on par with the standard engines.

Cylinder Head Tuning is a very important factor in Engine Tuning as it is closely related to increasing engine performance. By not only widening its ports to BITO R&D’s proprietary shape but also installing JB-POWER high-performance parts such as big valves and reinforced valve springs, the cylinder-head unfolds its true potential especially in combination with displacement upgrades, racing carburetors, and high-flow exhausts systems.
A good clutch should reliably transmit the high power of the tuned engine to the transmission without slipping, and at the same time, have high wear resistance. If this is achieved solely by harder springs, the clutch operation will become uncomfortably heavy. F.C.C. has established a system that consistently does everything from development, testing to manufacturing as well as a supreme level of engineering and manufacturing technology. Its technical strength and know-how make it possible to create strong but light clutches that are comfortable to operate and can withstand several hundred-thousands of clutch releases.
A transmission which’s dog rings have worn out after many years of use may not only suffer from slipping gears but also cause severe damage to the shift forks up to complete failure. By using its knowledge from countless race activities BITO R&D developed the Transmission Dog Undercut Service, a process where a perfectly aligned reverse taper is machined into the dog pairs so that they firmly bite which prevents the gears from slipping. We can accommodate requests for various usages scenarios from simple refurbishing to races.
