Accurate machining ensures correct bearing seating and minimal play, which helps reduce wear and improve throttle feel. This part is intended specifically for KE21SP installations and supports consistent running across varied conditions.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is special modification needed for fitment to KE21SP?

No special machining should be necessary when fitting to a standard KE21SP; install using correct bearings and follow the engine service checklist.

How does crank balance affect running?

Good balance reduces vibration and bearing stress. Check for smooth rotation and minimal play after assembly to ensure reliable operation.

When should I replace the crank during maintenance?

Replace the crank if journals are scored, there is excessive end float, or if power delivery becomes inconsistent despite other servicing.

Can this crankshaft be used in tuned engines?

Yes, when used with compatible components and correct setup it can serve in tuned KE21SP builds, but check bearings and tolerances more frequently.
