re: Got any Polaris RZR mechanics on here?

Yeah, I’d check the timing for sure. If it has the stock cam chain tensioner that works off of oil pressure it’s been known to cause the timing to jump, especially if someone hit the gas before the oil pressure built up. Mine would rattle for the first 15-20 seconds after starting so I put a mechanical one in it and fixed that. Mine was a fuel injected 900 rzr and the injectors got clogged after it sat up for a couple months. Started running bad and then wouldn’t start. When I pulled them out there wasn’t much flowing through them. I blew through the injectors with compressed air until they flowed. Started and ran fine after that. Not sure if blowing air through them is the best method but it worked for me.
