Default Downshift issue on quick decel

I tried to search on this topic and cannot get a hit. So I’m gonna ask the question here. When attempting to engine brake on my ‘17 Ultra Limited during a quick decel (to conserve brakes and be in first gear at stop), the clutch is not engaging in 3-2-1, again on quick decel. Is this a clutch switch issue or is the engine speed to fast for the clutch to engage in the selected gear? On previous bikes, never had an issue downshifting at any speed except to be careful not to cause rear tire to lock. I’ve had this issue since I purchased the bike w 7K mi on it about 9 mns ago. I really don’t like fully relying on the brakes during a quick decel, although ABS does help. I prefer to engine brake by downshifting from 5-3-2-1 but the clutch or tranny is not responding to the driver’s commands. Anyone have this issue? Thanks all.

P.S. On a separate note, just installed the Rinehart 45 Moto Pro 4.5” muffs and love them. Air intake and head pipes stock at this point. Seems to have provided a deeper, slightly louder note compared to stock muffs. May or may not do full Stage 1 later. Will see how she runs after muffs broken in.

Are you letting the clutch lever out all the way after downshifting?

Yes, I’m squeezing the clutch but the tranny is not slipping into the next gear selected. I have only experienced this with this FLHTK. As I said, all other bikes I’ve had will let you engine break upon downshifting.

Something is wrong with your bike.

Well, I’m due for my 10K service and plan on asking about this issue. I am under a valid ESP for another 4+ months. I’m trying to find out here on the Forum if there’s a problem with the bike or it’s just the way these horses are engineered. I’d like to hear from someone who has had the problem and found a solution...whether Stealer service or otherwise. Thanks.

I’ve noticed when you click a through a bunch of gears the transmission gets like lost. I don’t think this is a designed feature just a flaw with the transmission. It happens to me when I like pull over to the side of a highway and go from like 6-2 and let the clutch out. It gets to like a point where I can’t figure out what gear I’m in and even if I click all the way down it’s not in first. I end up just trying to get it to like engage whatever gear I’m In using a lot of clutch and when it kinda finds a gear then I can click down to 1st. But transmission works great if I’m sequential about my shifts or only skip one gear.

Take your time with the downshifts I'm sure it's a synergy thing here.

Peace.

Yes, I have just as you describe YheHateMe. Fairly often too. It’s like the tranny is shifting with a delay and looses its way. As you’ve said, come to a stop, nurse it back in a gear it can find, then downshift from there to 1. Unfortunately, that does not work when you’re engine braking to accomplish a quick decel. You’re forced into using both brakes to slow her down quickly. I really don’t think it’s a “synergy” thing either as suggested by Agoober. These bikes should be well engineered enough to accomplish a normal fast downshift such as 6-4-3-2-1 or 5-3-2-1 in a shorter stopping distance. Maybe I need to stick some fast “blips” in there to gain engine-tranny sync, but that’s not fun either when you’re trying to perform a quick decel. I still think this bike has an issue. Tranny or clutch or clutch switch or lever sensor or some damn thing. This should not be an issue. Can’t believe somebody else out there hasn’t had this issue and resolved it somehow. Will hand loose.

You need to read how a constant mesh synchronous transmission works..... They can't go multiple gear changes while stopped by design. The system needs to be moving.

Engine braking is not the proper way to do a quick deceleration. Use your brakes. Trying to manage engine braking while stopping rapidly increases the chances of locking up the rear wheel and is less effective than just using the brakes.

If I slow quickly I just downshift as I slow down, holding the clutch in. Sometimes I might have to let it out a bit if the transmission won't readily drop into the next gear.
