Scooter has never been down and only has 5500 miles on it.  So its most likely that it was built this way.

Been doing some digging into this and there is not a "factory approved" alignment procedure on the frame that has been released for public consumption that I can find, its either good or you replace it.  That's prolly why insurance companies are so quick to right them off these days.   But there are some aftermarket systems that check alignment with various methods.  And they use an adjustable dog bone to correct rear swing arm shafts that are not perpendicular to the ground.  They measure the distance between the shock mounts and use the dog bone to equalize it left to right. 

Since there is absolutely no adjustment for the 4 lower mounts, and the scooter tracks just fine, I think I will just level the frame off of the side plate and then see where the motor is in relation to it.

Then it looks like I can use an old three point link to replace the dog bone.  I'll set it up so it slips on, then count the turns to make it equal the length of oem.  Then try it both ways.

If it likes being shorter than oem, then I'll fab up something that looks decent and replace it.  If not, I'll put the dog bone back on.

Hi, well I'm at .042 quench and 81cc heads, 8.5 CR... and for problem free motoring, thats how its getting put back together. Built and in this weekend.

Thanks for all the input :)

may be problem free motoring, but will be soft at that compression and less than efficient combustion
you have done a lot of work and missed an opportunity
go back and read advice from rigidthumper (both posts)

Don't force it or "lever the motor over". Don't even "crank on the adjustors till it fits". Nothing good ever comes from that approach.

Without knowing the history of your bike it's hard to say what originally caused this but you can make it right, if you have at least some mechanical ability.

You have an SM, correct? Is there not a section on Vehicle Alignment in it anymore? Newer SM's - I know they've been pulling technical detail out of them over the years.

If you decide to do the alignment yourself, it's not hard at all but can take some time. You'll need a few tools likely (a couple of line lasers & a digital level that shows deviation). I also recommend removing the adjustors and "working them" a bit to free them up as they can be stiff. Put them back in with the same orientation.

There's a few good vids on YouTube for earlier Twin Cams that will walk you through. Although your dealing with a '19, the basics are the same.

Is it a

This clutch might just need the springs juggled so the strong (tall) ones are opposite each other so the pressure plate does not tip when it is released.

Or is it a

There is no fixing this clutch, you need a splined mainshaft to fix it. They split right down the keyway or the posts break off, a reinforcement ring only makes it slightly stronger, still easily broken. If you EVER dump the clutch (even accidentally) this is not the clutch you want.

I have a 2019 FLTRU that has a misalignment in the power train  It needs to be shifted to the right for the front link bolt to line up with the hole in the frame.  This is the amount of mismatch with the scooter upright on the table in the wheel vise.  No jack and not leaning to one side or the other.



On older scooters keeping the links free of load has been part of keeping the motor vibrations under control, and the manuals speak to being able to just drop the bolts through the links with no resistance.  The 2019 manual says bolt it up and torque it.  And on my twin cam, this bolt lines right up with the hole.

Now this scooter has had more engine vibration since day one, than the 18 it replaced, so I'm wondering if this is why.

And I'm wondering if I should fab up an adjustable link to install with no load, or just use this one and lever the motor over to line it up?

In asking folks around here, the answers run from "they are all like that" to "never had that issue on one"  And the ones who think they are all like that, just make em  fit. 

What do youens think?  And have any of you run into this on the M8 baggers?


I just got my 2019 cvo limited back together end of November and took a bunch of pictures on disassembly.
Put everything back on and the linkage rod lined right up.
I could see that maybe it would take a little nudge to drop the bolt through, but it WAS pretty close.
No vibration increases that I have noticed and I usually check things out every oil change.

“Make ‘em fit” well, maybe within reason?

Thanks for the update, SM told me to pull maxi fuse, then reinstall.
He suspects a bad BCM because both sensors throw a code as lost comm when it’s supposed to send a signal update every few minutes while riding and every 4 hrs when parked.

They have to hook it up at the dealer to check it, I’ll have to make an appointment when I have time.

We’ll see!

Mike,

This will give you the info on the display. As you can see, if the tire is high or low, it will indicate that. There is also an indicator that the TMPS is low on battery so you can check that. If the display is blank, then the TPM controller is not receiving updates regularly. If this happens on both tires without a low battery indication, I'd say you issue is with the controller on the bike.

If this LINK doesn't work for you, it's in your owner's manual.
