Yamaha Rhino Problem?

Does a side by side have a compression release to open so the starter can turn the engine over so it can start?

Yes, a Rhino does have part in the camshaft that bumps the exhaust valve open before tdc to lower cranking compression. A centrifugal weight swings the decompressor out of the way over 800 rpm's. This is done so that a high compression 4 stroke can be started by a smaller battery and starter.

The camshaft would need to come out. Individual parts are available but a complete camshaft with all decompressor parts costs less than $200

What year and model is it?

What problem does it have? Is the starter unable to turn the engine over? Is the battery in good condition? If the battery and starter are good, I would pull the plug and spin it over just in case the cylinder is full of fuel or coolant. If the cylinder is clear, the valve cover needs to come off for a decompressor inspection.

It makes a sound when you turn the key to start it and after you turn the key 5 or 6 times the engine will turn over and start.The sound is like a grind sound but not real loud.It sounds like the starter is trying to kick in but cant.Its battery is good,also put a new ignition switch and starter solenoid on it!!My mechanic said the starter was good but I dont know!!
