I didn't even think that they have an adapter plate for that unfortunately I already bought the bars that I want and the other question is are there any rubber bushings at all cuz I'm worried about the vibration and my bike it vibrates a lot

 

Hey I am interested in the adapter plate if that might be my best option. I have a question. Does it take rubber bushings and if you had one what would it cost?

 

I think I may have come up with a solution what if I installed grade 8 studs into the top of the risers where the cap bolts go. Either Loctite them in or even J-B Weld them in . and then use acorn nuts on the tops of the clamps. I don't think the risers would strip out again. Any feedback? Thanks again

 

Revzilla has some good videos on buying bars, and one of the things addressed is when you choose a taller setup like you have, natural forces cause the issues you are having because your hands and arms are pulling harder from the top and the taller bars are giving them a lot more leverage.They recommended a riser that is solid across the top for more gripping power. In my case, I got some thin soft aluminum (from Lowes) and cut it into strips and wrapped the bars about 3/4 of the way around---to make the bars thicker and it seems to work well so far. (I have plenty, so let me know and I will drop some in the mail)

As for the threads, I have had success by using a Q Tip and putting a thin coat of JB Weld on the walls and cutting new threads. Then I replace the bolts (5/16 allen head if I remember correctly for the risers) with stainless steel. They run about $2.30 each from my local hardware store so be aware.

My adapter plate came with the bike, but it looks like OEM Harley stuff---identical to the other one except for the beveled holes where it mounts to the springer fork. I have decided to keep the adapter plate---I change a lot of stuff regularly and Springer bars themselves are hard to come by because of the spacing of the knurling. It is a nice option to have laying around knowing I can swap out bars anytime. (It sure is hard being me--and expensive) I now wish I had kept a lot of the extra stuff I sold early on.

 

Just made some new risers myself in stainless steel for my springer project.
