I searched and read most of the posts about engine noise, loss of power, and backfiring. After we bought used 2013 Rzr 4 800 and was out for first ride, we noticed it was losing power. We initially thought bad gas, but I had also filled up our truck and was having no problems. Once we got home, I noticed a tinking sound from the engine area. After reading and searching the forums, I started taking the Rzr apart. I changed the oil filter and added 2 quarts of oil, but the noise is still there. The filter and compartment were recently cleaned prior to purchasing. I changed the spark plugs, no change in noise. I removed the spark arrestor and didn’t notice any change in engine noise, cleaned it and re-installed it. I took the valve spring header cover off and didn’t notice anything obvious. Rockers had good bearings, no excess play, the rods looked strait, springs in good shape, and there was some good new oil.

I’m not sure what to check now (may have hit my engine knowledge too) and I don’t want to take to shop and tell them I don’t know what is wrong and get a huge bill as they troubleshoot everything…
Thanks in advance… Shayne
