What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What is the recommended bore clearance for the M5002 pistons?
For the M5002 pistons, a typical bore clearance of 0.0025" to 0.0035" is recommended. This ensures proper thermal expansion and prevents piston seizure during operation. Always verify with your specific engine setup.
What is the compression height of the M5002 pistons?
The M5002 pistons have a compression height of 1.375 inches. This measurement is crucial for achieving the desired compression ratio in your Harley Evo engine.
What type of alloy are the M5002 pistons made from?
The M5002 pistons are forged from high strength 2618 alloy, which provides excellent durability and performance under high-stress conditions typical in performance applications.
What is included in the complete kit for the M5002 pistons?
The complete kit for the M5002 pistons includes two pistons, ring sets, wrist pins, and clips. This ensures you have all necessary components for installation.
How should I handle the installation of the M5002 pistons?
During installation of the M5002 pistons, follow the supplied instructions for piston to cylinder clearances and ring end gaps. Proper attention to these details is critical for optimal engine performance and reliability.
