The belts real easy to change, you don't even have to remove the wheel, just drop off the rear shock. You say it has had the wheels changed, is this a wide tyre conversion ? I've done two for friends, both came with off set front pulleys, both turned out to be aluminium and wore out within 15000 miles, so make sure the front pulley is good.
