Hello, -

I tried to find information on the outdoors temperature range for a Polaris Sportsman 450, but did not find anything.

This is the number for Polaris Customer Service:
1 (888) 765-2747
Hours: Monday-Friday, 7 am - 7 pm, Central Time

They have a convoluted process for sending an email, but I suspect no one will be checking emails outside the Customer Service hours for phone answers. See this page:

To send an email, first you need to search the Help Center. I used the word "temperature" and clicked on Search. Then the form to fill out to send an email appeared.

There are many things it could be but I think someone will need more information. I assume the battery is good. Is it turning the engine over ok? did you recently put new gas in it? Could there be fuel problem? fresh gas? Is it flooded? If so, let it set for a while and try again being careful not to give it too much gas. Do you know if it's getting spark? Pull a spark plug, leave it plugged in and place it close to the block, check for spark but be careful, it can bite hard if holding it in your hand. Maybe spray a "little" starting fluid into the air intake. Does it attempt to start? Do you hear any clicking from the starter solenoid? Have you tried to jump out the solenoid? Make sure you keep a trickle charger on your battery, with all this testing, you can run it down. Tell us what you've tried along with any other symptoms. More information is better. Don't use too much starting fluid or too often, it's extremely flammable but doesn't provide enough lubrication.

I suspect a bad connection from the relay to the starter, or from the starter to ground via the engine ground strap. More often than not there is a dirty/corroded connection somewhere. Check, clean and tighten all connections first. Don't forget the ground connections. (frame, engine, relay and battery) Apply dielectric grease to prevent corrosion at the connections and assist electric transfer. You may want to remove the connection, add dielectric grease and put it back together making sure your connections are free of rust and dirt.
Another idea is to jump across the relay terminals to see if it engages the starter or not. If it does, the relay is probably faulty, if it doesn't, I would suspect a loose ground connection or loose at the relay. Is the battery okay? Do you have a great deal of voltage drop on the battery while starting? Just because the voltage of the battery is ok, doesn't mean it is supplying enough amperage. Good luck, this is the way we learn, trial and error, keep at it, you'll figure it out.

check for a micro switch under the seat, on the foot brake system
indicates that by starting when pulling the wire you are breaking a ground circuit that stops it from working

The coughing implies that it's a fuel problem. It sorta wants to run but is not getting any fuel. Remove the air filter and see if it will start and run for a bit with a squirt of starter fluid. If it does, it's a dirty carb or something fuel related.

Not worth doing. It would involve a lot of work and money to do. You would have to basically replace two thirds of the engine to do it. Quicker, easier AND cheaper just to buy another bike with one already fitted.
