K&N RU-1720 Universal Clamp-On Air Filter Product Reviews

Thursday, January 10, 2019 - Part RU-1720
Fit a little tight on carb. Crushed 5 or six pleats in process. Covered with pre filter.

This is strictly a custom installation, and while the filter is working very well in this application, I wouldn’t characterize the installation as complete at this time, merely functional. I replaced the entire intake tract of a DR650 Suzuki, and the RU-1720 is the selected filter. The jetting of the new carburetor is very close to final, and the filter mounting just needs finalized so we can finish the jetting. At that point, I would be happy to send photos
