John,

Difference in rpm at 80 mph = 366 rpm

Stock Primary -

I guess that is the rule - what speed you ride at makes a bearing on the usefullness of the 6th gear. [smiley=xyxthumbs.gif]

Since I usually cruise at 75-80 MAX (with bursts to triple digits to blow out the carbon

Jerry, I wish my bike ran at 3295 at 80. That's what I'm shooting for. Like I said it depends a lot on the bike. The 01's were geared real low, wheelie bikes!

Puzzled,

Just thinking out loud here, but why not change your primary ratio to reduce your rpm's rather than go with the 6 speed?  Less cash for sure.

Hopefully with the Electra Glide Ultra the rpms's at 80 won't be much different (being that the Ultra weighs more) - in fact perhaps the 5th gear might be better because it will give me a bit more torque at speed...

Installed Bakers direct drive 6 speed in old Bessie. Lowered the ratio of the first 5 gears for better acceleration from a stop since I do alot of towing. In my opinion unless you want to accomplish something like I did then a 6 speed is a waste of money. You will never get a return of your money in fuel saved .

I agree I wouldn't do it for the fuel savings offsetting the cost. As far as that goes the cost of a 6 speed will buy a lot of fuel.

I'm after lowering the overall cruising RPM's. With this should come some added mileage to a tank of fuel. Stopping 8-9 times on the way to Florida stinks. So now it should be 7-8 times!

Did you use the 28 tooth compensating sprocket and what first gear ratio did you go with? When I figured out my ratios I'll be going the opposite way, loosing a little gear.

This is the drivetrain calculator in which you can put in lots of combinations and check stock vs. OD6 vs. DD6 and all inbetween combos...http://www.bakerdrivetrain.com/dialup/techinfoImages/rpmCalc.html

That is great. I've been doing it with a calculator and a piece of paper. [smiley=xyxthumbs.gif]

Glad it worked for you.  It really helped me to understand it all, too...

I think the cumulative fewer RPM's ought to buy a few % longer life also...

I need the extra 2-3 stops that you are saving for "Bio-Breaks"...  [smiley=drink.gif]

If you like it HALF as much as I like mine- you will love it!

Seeing I started this post I thought I'd bring you up to date on my decision and how it went.

I posted part of this in another post sorry for the replication.
