ok, ok,,,let me say and PLEASE inform me if you know otherwise ! After reading on the Big Bore for our bikes....it seems to me, even though the kits approaching 1000cc are more appealing to my base desires...the 904 kit is the most dependable if you are a daily rider type....which Bonnie and I fall into that category...so even though there is a part of me wanting the BIGGER Big Bore...the 904 seems to be the one to get ?????
