There is an O2 sensor midway between the engine and the muffler, but no secondary sensor after which means the system does not monitor the effectiveness of the catalyst. I did use a MX+ OBD Linc bluetooth enabled code reader which connected properly to the Port, but no codes (past nor current) were found set. The ATV only has 500 miles now and has shown high temps since new, now more noticable now with the 90+ temps we are seeing, and probably never noticed by me as my legs don't touch the rear fender. (Maybe the remedy is to never have the wife ride on the ATV). I have mocked up a plastic (wifes plastic thin cutting board) sheet to curve and fit over the muffler and mount to the existing mounting bolts for the existing small heat shield on the top of the muffler mounting (oviously to deflect the heat from cooking the above plastic. I have a sheet of thin aluminum to fit with the pattern and curve over the muffler with some space between aluminum and muffler surface to allow for air movement. I will also place adhesive - backed heat shield aluminized material on the underside of the rt rear fender (not sure how long it will stay in place, but is very inexpensive). Everything I read still points to the stupid EPA restrictions and the manufacturer's marginal efforts to add the non-removable honeycomb catalyst which results in high heat. I just cant imagine that other CFMoto owners are not seeing the same heat issues.....which are very numerous on the Polaris forums. I would love to hear from other CFMoto owners on their heat experience and remedies. Not sure what year CFMoto started adding the catalyst mufflers?? By the way, the muffler surface is clearly stamped that this muffler cannot be removed or modified under penalty of law with a fine up to $37,000. Go figure, as if someone was coming to get me! Sorry for long rant, but I needed to talk about it.

If i was buying one that new i would not buy it without a title. In Mississippi a title it is not required. Of course you have to have a title to tag it but even if tagged you cannot ride it on the road, they dont consider them road worthy. If i owned one that new i would want it completely legal with tag and title whether or not i could ride it on the road would not be considered. I had one with a snorkel it got in my way more than it helped, so i took it off, but i generally dont ride deep enough in the swamp to need it, its not fun when you get stuck in neck deep wter any way, been there done that dont want to do it again. I havent riden any new ones but im assuming the electric reverse is just electric shift, which is fine, no big problems with that i know about.

I would probably try wrapping with header wrap to nock down the heat , but 650 is quite hot, sometimes the ceramic inserts in the cat get brittle and break pieces can get lodged in the exhaust outlet causing heat build up, but yours is so new i dont expect that has happened, just a thought. I have never worked on one with a catalitic converter, but if it is equipped it probably also has an o2 sensor MAP sensor crank sensor and others that are relaying information to the ECU to adjust engine performance. Have you seen any warnings on display or is there a code reader port to get information from ECU

Cant go wrong with a honda, of course i say that, but it also depends on how bad it has been abused and neglected, you can usually tell by looking wheather the previous owner cared about his machine kept in garage or out in the weather. I like manual transmissions also i feel like they have more power in lower gears, and i like the control of manual on rough rocky terrain. Automatic is much easier just give it throttle and it goes nothing much else to think about. Not sure which one you are looking at but honda has an automatic transmission that is not CVT belt drive, very expensive to repair when it goes south , but they are very tough, if it has been taken care of you should get good service out of it.
