Hi, my names jade 25. Western NC Mom of two young boys. Who wouldn’t have a fourwheeler if I hadn’t picked up learning about what it took to repair a China 110 quad. That lead to a passion of atv repair. 5 months in and I’ve learned quiet a bit and interested in helping and learning how to fix my current Honda 87 250x that’s been through some hands as well as a china 50cc dirt bike that’s been rebuilt on the outside and soon learn how to replace valve stems and piston rings.
I need to replace a sensor on my son's Polaris Sportsman 110. It physically broke somehow. It's Polaris p/n 0455053 , the best I can tell. It's about a $140 part from Polaris. I'm hoping there may be an auto industry equivalent. Most of those are around $15 haha.

I know...I feel stupid for asking. I find it impossible to use the thumb throttle with my thumb when I have the bars turned full right. I have to reach across the top and grab the throttle from the front with my fingers. It isn't very smooth and I can't help but think that there must be a technique, mod or adjustment for this. How do I get past this?
2017 Polaris Sportsman 570 X2
Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.

I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?
I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
Thanks in advance!
Hi, does anyone know where to find the timing marks on the camshaft and how to orient them? I found the line on the crank and lined it up with the arrow on the case, but the only marks I can see on the cam are on the very end where the black plastic cap is. Are these the timing marks and if so how do you line them up?
I went out to ride my quad today. When I started it up it ran for a minute, then died. Since then it will turn over but won't start. I've check the spark plug and get great fire. I have had this quad for about 6 months, and very new to breaking it down. But need help. Thanks
