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 are the recommended bore and stroke specifications for the M2008 piston kit?
The M2008 piston kit is designed for an 87mm bore and a 70mm stroke, resulting in a total engine displacement of 415cc when installed in the Honda TRX400EX.
What is the compression ratio of the M2008 piston kit, and how does it affect performance?
The M2008 piston kit has a compression ratio of 12.5:1. This higher compression ratio can improve performance and horsepower, but it requires proper tuning and high-quality fuel to avoid detonation.
What materials are used in the construction of the M2008 pistons?
The M2008 pistons are forged from high strength 2618 alloy, which provides excellent durability and performance under high-stress conditions.
What should I consider regarding piston-to-cylinder clearance when installing the M2008 kit?
It is crucial to follow the supplied instructions for piston-to-cylinder clearance to ensure proper fitment and prevent issues such as piston slap or excessive wear. Clearances depend on the specific engine build and should be verified by the engine builder.
Does the M2008 piston kit include all necessary components for installation?
Yes, the M2008 piston kit includes two pistons, ring sets, wrist pins, and clips, providing a complete solution for your engine rebuild.
