Crankshaft Support Adapter GROM/MSX125SF

Details:
・ "Crankshaft support adapter" that changes the crankshaft journal from 3-point support to 4-point support to suppress crankshaft runout that occurs at high rotational speeds, and enhance the durability of the stock crankshaft. Patent pending structure.
・ Since the generators of GROM, MSX125, and MSX125SF are mounted on the L. crankcase cover, the flywheel mounting direction is outward (toward the shaft end). For this reason, the rotational weight of the heavy flywheel is applied to the outside of the crankshaft end, and in engines with improved pickup, the load during acceleration/deceleration doubles. As a result, the generator and flywheel may interfere, adversely affecting ignition timing, or in the worst case, the crankshaft may be damaged.
・ This product restricts crankshaft runout that occurs at high rotational speeds in bore-up engines by installing a ball bearing within the stator, changing the crankshaft journal from 3-point support to 4-point support. By restricting it, runout is suppressed, and the durability of the stock crankshaft can be enhanced.
・ Assembly structure that allows the crankshaft journal to be 4-point supported by attaching it to genuine parts, without the need to replace the crankshaft.
・ Essential for high-revving, high-response engines such as Takegawa's Superhead 4V+R bore-up kit. *Precautions:
・ Before purchase, it is necessary to check the stock crankshaft currently in use.
If the crankshaft runout exceeds standard values, runout correction or crankshaft replacement is required.
・ Due to differences in mounting shape to the stator complete depending on the vehicle name and frame number, the product number of the crankshaft support adapter differs.
・ Cannot be used simultaneously with Takegawa generator plugs (05-02-0044/05-02-0045/05-02-0046). Compatible models: HONDA GROM / JC61-1300001~, GROM / JC75-1000001~, MSX125SF
