2k7cheeta Posted October 11, 2013 Report Share Posted October 11, 2013 I have a 2007 banshee with just pipes filter and jets and vforce reeds. I rebuilt it about a month ago but I did not check the compression. So I just put a pro design cool head with 21cc domes and my compression is 180lbs on each side????? I'm at sea level and that just seems a little much for 21cc domes. Is this normal? Quote Link to comment Share on other sites More sharing options...
