5 spd vs. 6spd

This post makes no sense at all.
If you cut your gear spacing by one ( by adding one), you have an average of 10%-20% difference of range depending on the gear. The 6 speed should be the one trying to find the right gear when traveling a certain speed over varying terrain, as where the 5 speed gear box has a greater RPM/speed spread. I think your brother has less HP than you do.

The spacing between gears is greater on the 6 speed, which gives the given gear more range. I know what we experienced and have shared it here - not sure why you would think I'd lie about something as trivial as this.
Here are the final drive ratios for both for comparision:
2005 FLSTF
1st: 10.110
2nd: 6.958
3rd: 4.953
4th: 3.862
5th: 3.150
2007 FLSTF
1st – 9.312
2nd – 6.421
3rd – 4.774
4th – 3.926
5th – 3.279
6th – 2.790
As you can see, 1st - 3rd are much taller on the 5 speed, which means you're going to be going through the gears more quickly. 4th and 5th are much closer together so are going to be similar in usage. And 6th lowers the final drive ration considerably and increases the available top end.
Both bikes were stage one at that point and with the exception of 88 vs 96 ci were about as close as they could be.

Brilliant. Your statement above is flawed, as you believe they "cut the gear spacing by one" which is not the case. They stretched the lower gears, and basically added 6th on top instead of spreading 6 gears in the space of 5 as you suggest.

You went through that whole temper tantrum to tell me that he couldn't stay in 3rd gear, with your 6 speed while also in 3rd when both ratios are nearly identical?
Sorry about my miscalculations of less that .018 of a gear difference in 3rd. I really didn't think I needed to make a scientific point, and I guess we are both wrong about the trans difference. 3rd between the two is about as close as it gets.

Not the difference in a longer stroked engine of almost 10% CID power advantage could be the cause, no, it's GOT to be the 0.018 difference in gear ratio. Yes, that clearly must be the reason to take a bite out of my *** over this....
Maybe consider that simpleton tidbit before your next meltdown..
Cheers..
My apologies to everyone for this distraction...
I didn't mean to make this some sort of pissing contest.

Was always happy with the 5 spds on the 2 dynas I had. Had an 07 RK with 6th and a pretty much stock 96 and didn't really use it unless I was on the interstate running 75-80. It was good there. Have 10 Heritage with 103 and SE255 cams and love the 6th gear. It is usable at 60 and can roll on with throttle response without downshifting with the motor configuration.

What the hell do you mean "as close as is gets"??????Are you kidding?
.18 (not .018 btw) is a very noticable difference. 250-300 rpms easy.
Could easily make the difference between being at a shiftpoint or not.
and I guess we are both wrong about the trans difference

Yea, I'm not a fast rider for the most part but we've traveled long stretches of interstate and his seems to be right there. Can't say that I've ridden his on interstate though. Don't get me wrong, sixth gear isn't something I wished I didn't have.

6th Gear
I have a 2005 FLSTCI without 6th gear and a 2009 FLSTN with 6th gear. I do travel on freeways going 70+ and having a 6th gear is very nice! It saves gas and allows for easy cruising down the freeways. A big addition on the 2009 vs the 2005.........SJ Ron

definitely want to stuff a 6 speed gearset in my '06 Fatty, i roll alot of miles on the slab, so it's on the list

I'm not ready to give you a lesson in division, so I'll just let you believe what you want. it just isn't that important for me to debate.
