The generators of the GROM, MSX125, and MSX125SF are attached to the L.crankcase cover, so the flywheel mounting direction is on the outside (shaft tip).
Therefore, the turning weight of the heavy flywheel is placed outside the crankshaft tip, which increases the burden of acceleration and deceleration in improved pickup engines.
This can cause the generator and flywheel to interfere with the ignition timing, or even damage the crankshaft.
This product uses ball bearings inside the stator to change the crankshaft journal from 3 points to 4 points of support and limit the crankshaft sway caused by the high rotation range of bore up engines.
By limiting the ability to reduce shaking and increase the durability of the normal crankshaft.
Cannot be used with SP Takegawa generator plug (05-02-0044, 05-02-0045, 05-02-0046)
