This is a great carburetor with many universal applications. It commonly is used on the Suzuki LS650/S40 bike rebuilds as a replacement for the stock carb. It may need to be re-jetted for your specific climate and elevation. Carb jetting is not a one size fits all, you will likely need to try out a few different jets unless you have some locals with the same setup to share that tribal knowledge..

Here’s the specs…

  • 165/170 and 175 Main Jet

  • 45/50 and 55 Pilot Jet

  • 48-DDJ Throttle Needle

  • 7.0 Slide

  • Intake OD 62mm

  • Outlet OD 45mm

Here are some fine instructions on tuning your carb…
