WHY?!? the bolts go through bushings... a rubber gasket serves no use.

Lol. Yep. And breaking two 1/2" dia. Grade 5 bolts secured by a lock and large area washer through a steel sleeve threaded deep into riser bores is even more ludicrous.

I agree. the only reason I replaced mine when I installed them on my Street Glide was because they came in the urethane bushing kit with loc-tite on them already. One less step and less consumables for me.

Not sure why but this made me crack up lol. I appreciate that confidence, I guess I would generally appeal to this type of logic. Just having read a few threads on bolts shearing and noticing the trend of people installing stronger bolts recently, it made me think about it twice

Are you referring to a specific set? I've researched a few different manufactures poly bushings (which I would absolutely invest in with new bars) and none mentioned coming with bolts. Oh except the Alloy Art "Gooden Tight" bushings with the flush mount bolts.

The Rivcos with a sturdier base,that doesn't vibrate as much, have been on for 4 years.

That definitely makes sense to me, and I would at least; absolutely be investing in a poly bushing set while installing new bars to help isolate that vibration.
