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
