I have a 2000 Ultra Classic and same thing happen to me. I was on a run and I went to shift and found the lever on the floor board. I tightened it up, and a year later I had the same thing. When I made it home I put blue locktite on it. No problem since.

 

this is exactly why i always carry tie wraps with me if you break the linkage a ty wrap or cable tie works great at holding them together in fact i rode a hole season with a tie wrap instead of a helm joint.

 

I've read where several people take the allen head bolt out and replace it with a regular hex head bolt.
Mine on my '02 EG is loose & i checked it with a allen wrench. I plan on swapping it out with a hex head, a drop of blue locktite, & torquing it. We'll see how it goes...

 

The last time I had that problem I bought a new bolt and used green loctite.
It never came loose again.

 

I put up a thread on this a week ago,took advice from a post and took a mini grinder and opened up the space where metal meets metal.Then replaced the alen screw with a stainless steel,for strenth and to be able to torqe it more,hex head.Used 1/4 inch longer screw,and lock tight.Was going to put a lock washer on also but I forgot,was already back together.Tighted the snot out of that bolt,worked out good,I'll know for sure a few hundred miles from now.

 

For your future info Stainless is weaker then a regular steel bolt.

 

What part of "it's not the shifter rod" didn't you understand?

 

Apparently, ARP (the bolts and fasteners used by all the big names) is missing out on some good business here, LOL!

 

Now you tell me,but I think the head won't strip as easily.

 

Yep same problem here 08 SG. I have tightened the snot out of it it it still seems to come loose. It hasnt sliped yet but I am afraid its going too
