Customer Feedback

These filters fit 76-79 Suzuki GS750,s 79 GS850's, 78-79 GS1000's, as well as the big Kawasaki four cylinders from the 1970's that use the same rack spacing with VM26 Mikuni carbs (Z1/Z900/KZ900, KZ1000, probably KZ750). I will never run pods, and always search out a K&N dual carb flange universal filter for better rideability and consistency in the fuel mixtures between the inner and outer carbs.

Great fit and improved performance on my Suzuki DR Z400SM.

Great replacement to the factory cabin filter. Easy install ( two minutes ) No more dealer rip off prices. Been dealing with K&N since my days in the motorcycle business ( Suzuki & Yamaha ) in the seventies and eighties on long Island.
