My buddy used to own a sxr 600 red head and recall him saying that he took the 3 piece head??? gasket and just used one of the three layers to raise compression? Is this doable for my 2000 srx 700? and if so how is it done and what is accomplished?
Changing the base gasket alters port timing too. Some people were getting the stock heads machined. It's easy enough to do, but you need to find a spec as to how much was removed. I believe they didn't touch the squish area only took it off the outside edge of the head..................SRXtreme
