I own a 01 800 mxz and when I purchased the sled it came with a brand new speedwerx dial a dome head. I called speedwerx and they toldme it would give the sled 12 1/2 to 1 compression and that it could still run on pump gas, Does anyone have any experience or can you give me some ideas on what difference this will make in the way my sled runs.
