Engine Cylinder – For ATV Jianshe JS250, Baja 250cc & Yamaha YM250

Restore Optimal Engine Performance – High-Quality Replacement Cylinder for Your 250cc Engine!

Deep scoring, ovality, or overheating damage to the cylinder bore inevitably lead to a drastic loss of engine power, poor compression, and high oil consumption. After extensive operating hours or engine damage, replacing the cylinder is often the fastest and most effective way to restore the original performance of your ATV.

This complete replacement cylinder is a precise fit for the 250cc engine in popular models such as the Jianshe JS250, Baja Wilderness Trail 250, and the Yamaha YM250 Bear Tracker. It is ready for installation and provides the necessary precision to ensure full power and reliability when combined with a new piston set (sold separately).

Product Details and Benefits

• Replacement in Original Specification: Manufactured for an exact fit and long-lasting function.

• Restores Compression: Ensures perfect sealing and maximum power output of the 250cc engine.

• Long Lifespan: High-quality cylinder bore for minimized wear on pistons and rings.

• Broad Compatibility: Fits various common 250cc models (Jianshe, Baja, Yamaha).

Installation Instructions (Intended as Guidance Only!)

Important Note: Cylinder replacement is a complex engine job. We strongly recommend that this work be carried out by qualified personnel. The following guide is intended only as assistance for installation.

1. Preparation: Ensure that all sealing surfaces on the crankcase are clean.

2. Piston: Always use a new piston (or piston set) with a new cylinder. Mount the piston rings correctly onto the piston.

3. Installation: Lightly lubricate the piston rings and the cylinder bore with engine oil. Carefully slide the piston into the new cylinder and mount it onto the engine block with a new cylinder base gasket.

4. Gaskets: Always use new cylinder head and cylinder base gaskets (sold separately).

5. Tightening: Tighten the cylinder head (and its bolts) strictly in the manufacturer's specified sequence and with the correct torque.
