When mention alignment, I do get a wobble when not holding on to the bar in low speed. Yeah, alignment tools will be ordered... Hope this fixes the brake vibration, but I kinda doubt it hmmmm

I twisted the brake line so the brake switch wouldnt interfere with the sputhe bracket. No touching, tested it without shocks and rear tire installed

I'm also running the Lyndall Extreme pads front and rear.

With no front link, the drivetrain is still not constrained to a plane. With that setup, the drivetrain could pivot around the rear mount and the stock top link is pretty compliant.

Three heim links of equal length would be quite unforgiving of any imbalance, vibration, or runout.

Again, I'm mostly speculating here. I changed pretty much everything at once and did a 90% alignment before the first shakedown run. I also have a little 88" with pretty light and rigid exhaust so it's not exactly apple to apples.

I also have a little 88"(stock) with late dyna frame(06) and light exhaust (TBR). Thanks for taking your time and speculate. Just ordered digital alignment tools

No problem!

Wouldn't hurt to check that the rear rotor is straight/flat. I think the stock '06 rear caliper is floating, so it should be pretty tolerant of some minor runout. Maybe .010"? Mine isn't (Wilwood GP310) and I'm familiar with monoblock calipers so I'm pretty **** about rotor runout.

Yeah actually, I did a lot that season; I overhauled my cylinders and of course upgraded everything that I could. Engine got realigned and torqued to specs.

tbh I suspect it was the rear wheel bearings, because I also swapped them out and they were BAD 😅 now it’s like riding on clouds 👌
