Hey guys new to site and have question or two for ya my wife rzr s recently began to run really rough and backfires sometimes on decel or when just reved up at a stop. Also statred to hear little clicking from motor that comes and goes. It sat for about 4 months put some new fuel in it since tank was on last fuel bar new battery and started to hear the backfire and ticking??? Oil level is good and has 85 hours and about 1,100 miles so not quite to the 100hr full tune up but curious if it could be valve tick etc?? It did come and go then stayed constant last few miles of ride so.......im confused thanks guys!!!
