i love the airsal 65 from newbury, MA United States
Ya gotta run this kit and head with a 1.0mm base spacer or you'll detonate even if you're timed at 15 degrees. Ask me how I know. I've three bikes with the airsal 65. One runs a stock alu head. Two run the 44mm head. The one with the 1.0mm head did not detonate and runs flawlessly. The other 44mm head with the .35mm base gasket detonated.
