I ride a 2005 FLSTCI with the stock 5-speed tranny. I've been looking at upgrading to a 6-speed. What I want is 1 through 5 to be the stock gear ratio's and 6 to be overdrive. I've seen quite a few options and a few people have added their advice about Screaming Eagle vs Baker vs Rev-Tech. I don't have a mint to spend and am leaning toward the Rev-Tech. Any thoughts on quality, any problems or just general information would be most appreciated. I have baout 40,000 miles and do long distance rides whenever I can. Thanks.
