Where are the timing marks on a 2009 crf450?

On a 2009 Honda CRF450R, the timing marks are located on the left side of the engine, specifically on the flywheel and the ignition cover. You can find the timing mark on the flywheel by removing the left side cover and looking for a T or a mark aligned with the case. Additionally, the camshaft timing marks are found on the cam gear, which should align with the marks on the cylinder head when the engine is at top dead center (TDC) on the compression stroke. Always refer to the service manual for precise alignment and procedures.
