A number of Chief owners are proponents of replacing the factory belt final drive with a traditional chain. The benefits include:

• no belt squeal
  
• ability to run a wider (180) rear tire
• easy to repair a broken chain on the road
• lower cost to replace a chain than a belt
  

The process for converting the chain is straightforward, here are the parts you need. I have included duplicate part numbers where I could get them, for example you don't need to buy two separate rear sprockets...
