Oversize piston selection should be based on actual cylinder measurements, not only on the condition of the original piston.
Measure bore diameter, taper and out-of-round condition before machining. The cylinder should then be finished to the piston manufacturer's required piston-to-wall clearance.

When to Use a .020 Oversize Piston
A .020 oversize piston is used when cylinder wear, scoring or damage requires enough machining that the cylinder can no longer remain at standard size or .010 oversize.
Before machining, accurately measure cylinder diameter, taper and out-of-round. The finished bore must provide the correct piston-to-wall clearance for the Vertex piston.
When Should a Cylinder be Sleeved Instead?
If cylinder damage, corrosion or previous machining prevents the bore from being restored at .020 oversize, a replacement cylinder sleeve may be required.
The replacement sleeve is installed and then finished to the correct bore for whichever piston size will be used in the rebuilt engine.
Parts to Inspect During a Powerhead Rebuild
- Cylinder bore diameter
- Cylinder taper and out-of-round
- Piston-to-wall clearance
- Piston rings and ring end gap
- Connecting rods
- Connecting rod bolts
- Connecting rod bearings
- Crankshaft main bearings
- Crankshaft journals
- Cylinder head and valves
- Valve stem seals
- Oil passages and lubrication system
- Powerhead gaskets and seals

This listing is for the Wiseco 3208PS standard-size piston kit. Confirm the exact kit contents shown on the product listing before ordering any additional rings, pins, clips or related components separately.
What This Piston is Used For
The piston transfers combustion force through the connecting rod to the crankshaft. It must maintain the correct clearance within the cylinder bore while supporting the piston rings that seal combustion pressure and control engine oil.
During a powerhead rebuild, piston selection should be based on the actual finished cylinder-bore measurement rather than simply replacing the original piston with the same nominal size.
Standard Piston or Oversize Piston?
| Cylinder Condition | Typical Piston Choice |
|---|---|
| Bore remains within standard-size service limits | Wiseco 3208PS 79.00mm standard-size piston |
| Cylinder must be bored .020 oversize | Wiseco 3208P2 79.5mm / .020 oversize piston |
| Cylinder wall is too damaged for normal boring | Inspect for installation of a replacement cylinder sleeve such as 1185SA or 1185SC. |
Parts to Inspect During a Piston Replacement
- Cylinder bore condition and finished bore size
- Piston rings
- Connecting rod bearings
- Connecting rod bolts
