Anyone know when those drive belts typically go or is it something to leave alone. Does it happen way out on the trail or is there anything to check for? Im kind of green about this, been runnin my quad around the farm for years, about 2300 miles on mine and starting to do longer backcountry trips. Curious about a way to replace belt, videos or tips.???

 

Your owners manual what is the worn width of belt to be replaced

 

Here is a good vids on the Yamaha Belt system,all the Yamaha CVT ATVs use the same Yamaha Ultramatic transmissions. I just check the belt on my 350 Grizzly and it looks like new with 2000 miles on it. I seen them look like new with 3500 miles on them.
Bottom video is how to change a belt. Its a Kawasaki but there all done the same way.
