I just bought my 1st RZR. 12 800 trail. last week I installed a snorkel that I made. I notice since I did this I hit my rev limiter all the time now 6300 is this normal? I also put a T fitting in my crankcase breather to route the line higher and I had a knocking sound and I notice if I put my thumb over the hose a little it goes away so I took the hose off and put the breather back to stock.
