Risers "loose"
Good morning everyone,
Back in 2017 I installed a new triple tree on my 2011 to support custom risers. Ever since installing the new risers (I believe they're 6") the risers slide a little bit. I thought maybe I didn't get the proper diameter bolt, but not entirely sure. It has movement within the riser. I can take a video if need be. I also find that sometimes that bolt is a bit loose. I can tighten it with my hand while I am riding. I am not scared the handle bars will come off since the bolt is extremely long.
Any tips?

Blue Loctite and the proper torque per the instructions provided with your custom risers should solve the problem.
Would probably be a good idea to get the correct size bolt, if you are not sure, you probably should get someone with mechanical knowledge to help you.

Thanks for the response. I cannot find the torque instructions on my risers. These are the risers I have and cannot find any information on them. As for the correct bolt size. I believe I got the right one a while back but will confirm today.
Perhaps all I am missing is the torque and Blue Loctite. Can I find the torque on Harleys website? or is this specific to each riser?

Spec would depend on the grade & size of the bolt installed. Grade 5 1/2-13 is 75 foot lbs, Grade 8 1/2-13 is 105ft lbs. That said, those are aluminum risers, all bets are off with those!

From the specs looks like 1/2 -13 thread pitch is the bolt size. For that size bolt in aluminum it is 26 foot pounds of torque per standard torque chart.
My service manual for a 2019 FLHTCUTG shows 30-40 foot pounds of torque along with using blue loctite.
If you do not have a Harley Davidson service manual, it is one of the most import things you can have when working on your bike, well worth the $$$ spent.
What type of bushings do you have in the triple tree that support the risers? OEM or poly?

Thanks for that. I have OEM bushings (I believe. Cannot be 100% sure because bought a used triple tree to get rid of the old 2011 triple tree that does not support custom risers). As for the your service manual, you're saying that aluminums risers + that bolt should have 30-40 based on your manual?

I use solid bushings with 16" apes of 1.5" risers, and they do not move a millimeter.
Cheers!
