[smiley=nixweiss.gif] My humble opinion....I had the Screaming Eagle six speed gears installed in my 2003 Road King at the same time I had the engine stroked to 103....as stated previously when riding with the five speed tranny I always wanted to shift up one more time. On the highway I felt like I forgot to shift to 5th, but was always already in 5th.
New six speed, 103 engine..ready to go....have to be doing 70 - 75 plus to feel comfortable in 6th gear...engine seems to be lugging at anything below 70 miles an hour.
2006 SE Ultra... operates smoothly with the stock 5 speed. I would not change it to a six speed. As a matter of fact I just had my 2003 Road King converted to a trike for my wife and had the six speed removed and replaced with a five speed (mainly because there is not a reverse kit for the six speed0, even though it will be out soon, I decided to change back to a five speed. The convertor swapped trannys out with me.
Now I am gun shy....I have a Red/Black SE Ultra on order that will be in in November....I really do not want a noisey 5th gear!!!
