Cheers TinCupChalice, now that is really interesting, I also have a 2013 Fatbob and looked at the Harley notice you posted, I looked at the Jiffy stand Pin and mine is the opposite way round from the Harley installation Manual, now is this the correct way that they are talking about in their notice, or should it be as in the Manual.
My jiffy block pin is pushed in from the rear to the front as well. Guess my '13 and your's had the same jiffy stand installer guy on the assembly line
Honestly, I thought all the Dyna block pins were pushed in from rear to front; I've had mine out and put it back just as I found it.
And, on your headshield clamp touching the brake rod; you will get some added buzzing or vibrations from that. The exhaust is mounted to the engine moving while the brake rod is stationary and part of the rolling chassis. Nice catch on that as well
Cheers TinCupChalice, yep we can only iron them out bit by bit, but with all the extra addons that you can put on a Harley, difficult to find them all, but at least it takes a few buzzes away.

They're continuous works in progress; we keep improving them at every step and make them right. Some aftermarket parts do make it more challenging but it can be done. If we keep the bike in correct vehicle/engine alignment, isolate the rolling chassis from the components riding on the isolators, we can make these bikes smooth, with the pulses and vibrations in all the right places

Yes, it's part #22. That image is reversed but I'd bet your jiffy block pin is installed rear to front as well...
Thanks Tin. How would that effect vibration? Secondly, I don't have a feeler guage at the moment to measure the gap at the top of the front motor mount but is there any correlation between the top gap and the bottom gap of the mount? I can almost put my pinky between in the gap at the bottom. Without measuring it, i would guess at least 3/8 to 1/2" gap. Attached find the pic of the gap. Thanks
That discussion on the jiffy block pin was more of a curiosity question since the HD diagrams show it going in front/back yet in reality it's rear/front. The jiffy is solidly mounted to the rolling chassis and unless it's contacting something it can vibrate against, as in Smogbob's case, it should have no effect on vibrations.
It's really hard to say with the rubber isolators; they can look fine yet still distort when you're riding. That HD service bulletin is a guideline but their solution of removing material isn't the true answer. Once the rubber begins to distort it never comes back again, it just continues to distort more.
I lost my original front isolator very early on and needed to do the vehicle/engine alignment and replace the isolator. I needed to shim the front isolator 1/4" to put the isolator where the alignment wanted it, and it did last for a time but I knew last fall it was failing again which is why I went to the Predator front mount this time.
I do regret I didn't do the Predator the first time, the difference is amazing. The bike took on a solid, firm feel. There was a slight increase in vibrations below 2500 RPM but not in a bad way, more of a connected way. It's hard to explain but I won't ever use an HD engine mount again
If that isolator is close to the engine bracket, and you've got a few miles on the bike, it's very possible as you're riding it can contact the bracket at certain RPM ranges...
Yep Jiffy pin not touching anything, I cannot see why it would give vibrations, I was just curious as it was like yours the opposite way round, Maybe Harley do it this way now.

I suspect they've always done it that way, honestly. My '01 Low Rider and '03 Wide Glide were the same, block pin in from the rear. I always figure the diagrams and the service manual are more like guidelines, than actual rules
My 98 is in from the front. If you search enough on here you'll see there many recommended to have it going in front to back as in some it can contact the case. When it goes the other way. I don't think clearance is an issue in all cases. I had mine out to replace the jiffy the other day and it didn't look like it would hit either way but front to rear definitely left more room by a lot.
I have a 07 wide glide. My jiffy pin went from front to back. Just like the pic and it was touching the case when you hammered down. I flipped it around and took care of the problem.
