How do you change cbr 150r timing chain?

To change the timing chain on a CBR 150R, start by removing the seat and side fairings to access the engine. Drain the oil and remove the engine cover to expose the timing chain. Carefully align the timing marks on the camshaft and crankshaft, then remove the old timing chain, replacing it with the new one while ensuring proper tension and alignment. Reassemble the engine cover, refill the oil, and reattach the fairings to complete the process.
