I have a 09 Nytro XTX and my belts last only 250 to 300 miles.I had dealer install a 1.75 inch track but it was not geared down. I ride here in Alaska at elevation of 500 to 2600 feet with temps of 10 to 38 degrees.My riding is off trails climbing short steep hills with lots of stop and go throttle.Is there any solutions to get better mileage out of a belt.I run everything stock. Please help.
