Review on AHL 1 20Mm 4 00Mm Adjustable CRF450R 2002 2012 by Marc Farrell

They are very inconvenient to buy, unfortunately I didn't notice this until I went to the valve adjustment. The problem is you get 1 of each size. And you get very big jumps between sizes. It is best to simply check the gap dimensions, calculate and order the appropriate seals. I was unable to use any of the pads in this kit due to random jumps in size and the need for multiple pads of the same size.
