Product Description
● Crankshaft ASSY Weight: about 1,870 g. ● Since the crankshaft is damaged, it is necessary to install it simultaneously with a lightweight outer rotor (weight of flywheel 700 g or less). ● Since the top dead center position drops by 0.8 mm, there is no physical contact with the valve etc, but the compression ratio rises around 0.6 (in case of bore 52 mm) compared with the case of 41.4 mm stroke. ● Monkey FI is not possible. ● Simultaneous wearing with a lightweight outer rotor is required. ● Recommended for our Hyper Head Big Bore Kit. Since the top dead center position is lowered by 0.8 mm with respect to the normal crank, it can be mounted without changing to a dedicated piston or the like. ● We do not recommend use for our normal head compatible big bore kit. Engine characteristics deteriorate, the original performance can not be demonstrated.
