All experience with its predecessor have been completely incorporated in the development of this engine. The result: an uncompromising competition engine, specially tuned for the demands of a .30 engine! The massive ZR.30 X Competition XTEC T6 crankcase provides the engine with a high structural rigidity, with extra thick ribs, especially between the front and rear ball bearings. Also the carburetor is completely revised. The LRP XTEC PowerCarb 3 carburetor is flow optimised resulting in maximum performance and easiest tuning. Extra large surfaces and the special foot made of synthetic material with an aluminium core optimises the temperature management. This leads to a perfect cooling, an optimum heat isolation from the crankcase and a more constant running temperature.
