1997 YZ125 intake boot. This boot fit perfect and works great with my Boyeson Reed valve. The original Boyeson intake boot had become very stiff and a pain to put the car but on and sealed property. I purchased this boot in May and finally got around to installing it last night. I used to dred taking the carb off to clean it. Now with this new intake boot it's a simple job like it should be to take off and reinstall the carburetor.
