My 2013 Polaris 850 XP is running a little rough at idle. Took it to my mechanic for a look. Mechanic stated the stock plugs are not hot enough for up state ny temperatures, he said the plugs are installed one size fits all. Ordering new hotter plugs to be installed today. Other than that this machine performs great. Anybody else ever had problems with spark plugs not being hot enough?? Thanks

 

Just my old on this one. That's what Polaris Digital Wrench is for. All he had to do is hook it up and remap the fuel/air mixture,etc rather than try to compensate by changing plugs. OPT
