Rear Fender Rattles

[Slayer69]

I recently completed my Frankenstein Trike kit install on my 2015 street glide. Everything went fine. Got the fenders back from the paint shop and installed them and now have a loud rattle in the back fenders that starts at about 3000 RPM but eventually settles out when the speed stablizes.

I've checked my motor mounts, all the bolts on the kit are torqued to spec. I can grab the fender brackets and that reduces the vibration to the point that the fender no longer rattles. Not sure what else to look at. Hoping someone on this forum has an answer or suggestions.

Slayer,
I've built a bunch of the Frankenstein trikes and I cant say that I have run into a rattle like you describe.
Take a look at the swingarm bushings and proper install, that would be the first place Id look. If that all looks good, than check your shock mounts/bushings. You're going to have to track it down, but you'll find it.
