The compression for a 1991 Yamaha Bravo snowmobile should typically be around 120 to 130 psi (pounds per square inch) for each cylinder. It's essential to check the specific service manual for your model, as compression can vary slightly based on the engine's condition and any modifications. If the compression is significantly lower than this range, it may indicate wear or damage that needs to be addressed. Regular maintenance can help maintain optimal compression levels.
