Crankshaft Support Adapter GROM / MSX125

Details:
・"Crankshaft support adapter" changes the crankshaft journal section from 3-point support to 4-point support, suppressing crankshaft runout that occurs at high RPMs and increasing the durability of the stock crankshaft. Patent pending structure.
・Since the generator of the GROM/MSX125/MSX125SF is installed on the L. crankcase cover, the flywheel mounting direction is closer to the outside (shaft end). This causes the rotational weight of the heavy flywheel to be applied to the outside of the crankshaft end, and in engines with improved pickup, the load during acceleration and deceleration doubles. This can cause the generator and flywheel to interfere, negatively affecting ignition timing, or in the worst case, damage the crankshaft. This product changes the crankshaft journal section from 3-point support to 4-point support by installing a ball bearing inside the stator, limiting crankshaft runout that occurs at high RPMs in bored-up engines. By limiting runout, it can be suppressed, and the durability of the stock crankshaft can be increased.
・No need to replace the crankshaft; it is a mounting structure that allows the crankshaft journal section to be 4-point supported by installing it on genuine parts.
・It is essential for high-revving, high-response engines such as Takegawa's Super Head 4V+R big bore kit. *Precautions:
・It is necessary to check the stock crankshaft currently in use before purchase.
・If the crankshaft runout exceeds the standard value, runout correction or crankshaft replacement is required.
・Due to differences in the mounting shape to the stator complete depending on the vehicle name and frame NO., the product number of the crankshaft support adapter will differ.
・Cannot be used simultaneously with Takegawa generator plugs (05-02-0044/05-02-0045/05-02-0046). Compatible models/compatible frame numbers: HONDA GROM/JC61-1000001 to 1299999, MSX125
