As best as I know there is only one 7 speed and that just lowers the gears. 7th gear is the same as 6th gear in the stock 6 speed. So what you end up with is lower gears and less of a split between the gears. If someone know different that may explain why some work and others don't.

Agree; AFAIK Baker is the only 7 speed trans on the market.  Yes, DD7 1st gear is 12% lower than stock 1st gear  Yes, 7th is still direct (1:1) like stock, so yes the DD7 is a closer-ratio trans than stock.  Makes that variability a head scratcher.   

I pull a trailer and live in the NW having the closer gear ratio is great being in the power band all the time. I can see living in Florida why you wouldn't need it the largest hill is the overpass down the road.

Ditto.  Riding 2-up and pulling a trailer on steep grades and high elevations (many over 10,000 ft) of the mountain passes of western U.S makes the DD7 a big benefit.

When I had the DD7 in my '08 SEUC (stock ECM with PC5), Dyno Jet reprogrammed the ECM and cruise worked in all gears.  Now, with TTS on my '11 SERGU, don't know if that's an option...ECM may have to be stock.  Anyone have thoughts on that, or on use of Power Vision to reprogram gear ratios?

'Spoke w/ FuelMoto around Daytona (Bike Week) and Jamie said that they (DJ/FM) didn't have a fix for the Vision, but would work on that when DJ got back from Daytona. I don't know if that was just for the '09s or the later models as well?

AFAIK, Techno Research has the solution.

Do a cam change. Easier than a gear swap.  And way cheaper.   120 torque is a game changer.  Then 6th gear or 7th won't even matter at all.

'Went to a 117 w/ T-Man 625s but the planets were in alignment for the DD7 also

The CruiseDrive 6th and the DD7 7th are both 1:1, the benefits of the DD7 are the lower first gear, the closer ratios, much smoother & quieter 

[Puzzled]

Any fix for this yet?

I ask as I went to a shorter rear tire thus changing my overall gearing and I no longer have cruise or sixth gear indicator light. I don't know if I'm chasing something similar or not. I do know I saw the light a few weeks ago after the tire swap... or at least I thought I did.

Waiting on a call back from a dealership. They have two identical bikes both with the baker 7, One works great and the other doesn't. Both have the exact same calibration in them. We are working with them to try and figure it out but were on there schedule not ours. They built both bikes for two brothers, so the only thing different on the bikes they say is the custom paint.

[Yellow09SERG]

Stu, that 120 torque does feel great behind the cruise drive, but throw that same 120 behind the 7 speed and there is a huge difference again. I am 250-260, wife is not a skinny girl either, then throw the trailer, or start pulling the hills in NW AR and dang that lower first gear is really nice. Maybe by the time I can get the parts and money together to build a motor, someone will have a fix for the cruise. Even now just having cruise in 7th I am very happy with the tranny

[FlaHeatWave]

The Boys at Oasis do 'most as much Baker as Bert does... 'They have the (Techno Research) "fix" for the Cruise / Rev Limit with the 7...

With the PC-V/Auto the cruise works in 7th.

T.R.(T-Man 625 Cams, CVO Street Performer Heads) & Bert (DD7) are playing very well together with the "Yellow Cruise Missile" (117 '09 SERG).

'Curious to see how the Clutch (stock/SE Spring) works in the upper operating range?

So no real answers yet on this, I just ordered the DD7 and was planning on ordering the TTS to set up the ECM as I use Cruise most of the time on the HWY and don't want to start my next trip without it. Maybe the speed sensor is having a hard time reading the helical gears? We use a similar sensor at work on the caterpillar engine flywheels, you can actually test it with a volt meter as it will generate 10 Volts at speed then check the frequency with an ocilloscope to see if there are any missing pulses, does the speed sensor in the harley work the same way? I know the installed distance from the teeth is critical and any filings on it will weaken the signal. There is some mention of a different thickness gasket for the speed sensor in the DD7 kit so the installed height must have been an issue.

[Steve Cole]

Currently we know there is something going on but no direct answer. We have also found the the sensor itself has been changed along the way. So at this moment in time we think it is a combination of things that causes the issue and need to still trace it down further. Regardless of what we end up with the cruise works in 7th without issue as it is the same as 6th, it's just the lower gears that we are chasing. HD also uses a different calibration when upgrading the early 6 speed to the later 6 speed and the only thing different between those is one had straight cut gears and the other helical cut. So we've got plenty of variables in the mix right now and we are trying to sort through them all to find a fix for them all.

I'm still waiting for an answer from Fuel Moto and/or Dyno Jet.  Jamie did an awesome job tuning my bike, so I would prefer not to mess with the rev limiter or change the tune.  However, with Sturgis looming, having cruise control in 7th gear is a must!  I'm not sure what is taking Dynojet so long to solve the problem?

I have gotten the cruise to work thanks to Steve he is having me try this fix  and verifying that it is going to fix them all and then he will release it.

I know this is an old topic but wanted to update for future reference for all. It may have been addressed in another thread but I didn't find it. The TTS tuner has a tab now that will allow you to select the Cruise Drive 6 speed or the Baker DD7. When you select the DD7 it corrects the ratios and cruise becomes functional again in 4th-7th gears. Thanks Steve

[KEB]

I made one small change to the top gear ratio with the power vision and it was fixed. Cruise in the top 3 gears works with a green light. The new ratio is 0.67333.

The ECU now interprets the DD7 1st gear as gear "0" with top gear showing as 6th or at least that's what the powervision shows.
