Dyno sheets do not reflect how these bikes feel stop light to stop light and traveling on the interstate at lower speeds 2-3k RPM. The 585 below 3K is not "on cam". Overlap interferes with clean running despite a good pipe and tune. In reflection (remember I mentioned nuances and this is how they actually feel not the dyno sheet WOT from 2K up in a high gear) the Wild Things cams act like stock as does the SE259 or TR590 and when the compression is proper provide a more enjoyable ride. Both and others can all hit a number.

Thanks Mike. I just made a tranny change and though it didn't completely solve the problem I think I can survive till I came add cubes to my 110

With the lower / close ratio gearing of the DD7, I would think that a cam with a little more to the right would be good to go.

From my experience with the 259s in the Stage III, a midrange cam like the 585s might be just the ticket. 'Hope the 625s going in the 113 aren't too far to the left for me, I just fell in love with the (dyno) curves of Jim's (Metal Dragon) 113...

Those 260s just aren't suited to a loaded touring bike... 

[HD Street Performance]

The 260s aren't suited for anything even if they were give to the user for free IMHO
There are some decent SE grinds that work when appropriate for the combination of parts and the users needs, those are the SE204, 259E, 263E, 266E, maybe more but that is all I have direct experience with. The TR625 is a very strong grind as are most of his are and once again they have to be matched to the parts and riders needs.
There are some that I would consider obsolete and also ran.. 251, 211, 203, 258, 257. Too many others out there, both SE and aftermarket, have just passed these up

Which tranny did you go with?

Just installed a DD7 and first response to it is I love it

[Yellow09SERG]

I have to agree with you both on the SE260! As I said earlier they are worth less. To heavy to throw out of sight and to light for an anchor. But with the tranny change it works well enough. Bike has 42,000 on it and we all start to wonder about the 110 at that point in life span. I'll will probably just live with it this summer as there is no major rides planned, just the normal weekend blast through the hills of AR. Really waiting on the outcome and thoughts of FlaHeat's 113 build and what he thinks and what he would change. Bad as I hate to say it, it's still winter here and I could very well already be planning next winters projects.....lol

I went with the DD7 as well.

not to jack the thread, but jacking the thread....

to those actually using a dd7.. i need lower first and second gear desperately, usually run in 5th, use 6th once in awhile. run a 07 ultra with a TLE.. 1650 gcvwr

trikes come with 30 70 gearing - its pretty easy to go 30 - 68 on a 07 bike and use a stock belt but its a pile of work to do plus its not exactly free.

is the first on the dd7 deep enough to get near to what a 30-68 would be?

next time i do any work i plan on doing the gearing, have to take the primary completely off to do it and then have to mess with a tuner to fix the speedometer..  i have not had trouble needing reverse except two or three times and then just get off and push.

just trying to get real world thoughts.. finances are such that either one precludes the other...

timo can't really give you an answer on the actual gear ratios but I am betting someone can. I also have a thread in the drivetrain section on the DD7 so ask the question the also. What I will tell you is that the DD7 was a one of these days I'll get one till right before Thanksgiving. A buddy of mine rides a 09 SERG that has had the DD7 installed and pulls a trailer on a regular basis. Long story short rode his bike one afternoon and OMG that lower first gear was great. Now I know the trike is a little different animal but can't help to believe the DD7 wouldn't be a great improvement.

The DD7 will make a difference in the lower 2 gears.  I'll know more after my Dyno this month, but just in riding, I could tell a big difference.

[Yellow09SERG]

Even with this mismatched cam I am running there is a huge difference in the bottom end

[GMR-PERFORMANCE]

We have run the 585 into the high 10.8 range for comp and it still has a soft feel down low. Larger CI that will be reduced by 117 CI its gone and that cam will rip off the lower rpm range.

Timo,

What is the gearing on your '07?  30/66, or what?  I have the DD7, which I've used in a SEUC3 and an FLTRUSE, and have towed a Bushtec Turbo +2 (fairly large, heavy trailer at max load) with and without the gear change and the tranny change.

Before I put the dd7 in the SEUC, I replaced the front 32T pulley with a Tri-Glide 30T, which changed the ratio from (66/32 =) 2.0625 to (66/30 =) 2.2.  That made 1st gear (and the 5 others) 6.7% lower [(2.2 - 2.0625)/2.0625 = .0666 = 6.666% = 6.7% rounded off].  That helped markedly, but...

In comparison, the dd7 1st gear is 12% lower than our stock 1st gear, nearly twice the change of 32-66 to 30-66.  But wait! There are more benefits than that, since its top gear is still 1:1 like the Cruise-Drive.  With the "tooth loss," that meant more RPM in any gear, at any speed, than stock--enough to be noticeable when running 70 to 80 mph.  Also, since the dd7 is closer ratio between gears, there isn't as much RPM change when shifting.  I really like the effect it has on the bike; makes it much easier to get off the line, much better for slow maneuvering, and you don't get caught in the middle as much, where one gear is too low but the next one is too high.

The only dd7 drawback so far is that cruise control works only in 7th.  Apparently there is a fix for this with TTS (which I have) and Daytona tuners, but we haven't zeroed in on exactly how to do it.

Hope this helps.  Sorry for the

I really noticed this when I was in the mountains out west last year with the CruiseDrive.

You will need to change the primary Ratio in your Mastertune if its a J1850 bike. The stock setting will be 1.353 and you need to change it to ~1.430 for the DD7 to work. The people that have done this tell us that the cruise now works in 5 - 7th and some say it also works in 4th.

Forget the thread jack....lol. I think I am the op on this one and we are learning and getting smarter.... Isn't that what we are here for?
