KTM Duke/RC 125 Top-End & Bottom-End: Valve Clearances, Camshaft & Con Rod Bearing R&R

Описание: This is the ultimate deep dive into the top- and bottom-end of the single-cylinder engine found in the KTM Duke 125 and RC 125!

This video covers several critical, advanced maintenance and repair tasks: checking valve clearances, removing the camshaft (a necessary step for cylinder head removal), and inspecting the crucial connecting rod big end shell bearing.

This information is essential for diagnosing engine knock, performing major rebuilds, or simply doing advanced routine service that goes beyond a basic oil change.

⚠️ IMPORTANT SAFETY & TOOL NOTES:
This repair requires precision, torque wrenches, micrometers, feeler gauges, and specialized tools.

Engine timing must be set correctly using the specific KTM Timing Pin before valve clearance checks or camshaft removal.

Refer strictly to the official KTM service manual for all torque specifications and tolerance limits.

🛠️ Key Procedures Covered:
Valve Clearance Check: The process of bringing the engine to Top Dead Center (TDC) and using feeler gauges to measure intake and exhaust valve gaps.

Camshaft Removal: Loosening the cam chain tensioner and removing the cam gear and camshaft for cylinder head access.

Cylinder Head Removal: Safely lifting the head off the cylinder barrel.

Connecting Rod Big End Access: Separating the crankcase to access and inspect the con rod shell bearings and crankshaft surface for wear, scoring, or failure (the common cause of engine knock).
