Toomey Banshee Posted September 18, 2005 Report Posted September 18, 2005 You could probably get away with 20's as well. 21's for sure. Quote

Tim C Posted September 18, 2005 Report Posted September 18, 2005 I have 21cc domes and about 150lbs of compression at sealevel - I could not run 20cc domes on pump gas Quote
bansheeryder21 Posted September 18, 2005 Report Posted September 18, 2005 I just ordered a new head and 20cc domes from dlnoss. I am at sea level as well. He said that 21cc domes with no porting and no advanced timing is fine with pump gas. With 20cc domes he said to use 20% race fuel with 80% pump gas! Quote
