More information and directions would be great :?:  :?:  :?:  :idea: ....

Regardless of manufacture, If they are driven by people that abuse them and pushes them way over the safety limits, they are going to get bit and will end up hurt and even dead. They must be driven responsibly and with care. in no way is it the manufactures fault and they can not always see every situation and prevent it. most of problems are driving under the influence, Overloading, sever modifications of the of UTV"s themselves, Under-aged riders or drivers. Going way, way to fast. All of which is the owners responsibility and not the manufacture :idea:  .....

I have been giving it some thought on a fan bypass on mine but yes if there is no flow or the radiator is plugged up like mine gets now and then with the dead wild flowers getting sucked in it that will not fix the problem. I had a boil over problem that happened last trip and and so fare the problem has not been found on why it did it. At this time I am not sure if it was a stock thermostat or the PCM did not receive the Fan on command from the temp sensor or it was a stuck fan. Air trapped in the system would cause the fan not to come on and there is a procedure to purge the air and most of it was stated on my first post with the exception of removing the bleed screw on the thermostat housing.

As for a fan bypass switch, There may be a problem since the PCM senses fan load and it may set a trouble code light if it tries to turn on the fan while the bypass switch is in the on position. this will be tested next week when I try to do one on mine. this may only be an issue on pre 07 models that use a PCM and the newer one have changed out the system and may not include that function...

It is simple, The main topic would be other UTVs as the main title, Sub catigorys would be each manufacture regardless of the decusion type. If it regarded anything that was honda big red related it would be in one thread under the honda thread regardless of topic. So under other UTVs it would have a honda thread as well as a joyner thread and so on and so fourth.  :idea: .

All pre 2007 ranger transmissions had a whining issue and that is normal. If you inspected all the components and bushings for ware and it all checks out there is not much more you can do if you are running the proper fluid and it was assembled properly. I have never heard of the cases distorting as well. As for the backlash it may be case ware when it ran out of fluid and I am not aware of Polaris haveing different shims to compensate for this but maybe it is something that can be fabricated.....

Sound like something is overheating and shutting down. It could be the ECU, bad ground or even the voltage regulator but there is no way of knowing with the information provided......

That wont fix the problem due to the fact that your charging system is not big enough to run all that stuff and all you are doing is upping the capacity and not the replenishment of the battery. install a battery maintainer when the UTV is not in use....
