Default Lower riser stripped out

95 bad boy Springer.



The part that the bolt goes into on the lower part I'm pointing at has stripped out. What is the process for using a helicoil? I've never used one. The bolts are 5/16 diameter not sure on thread pitch.

Thanks guys

I'm pretty sure thread size is 5/16 x 18. Can anyone confirm that?

Is it a set screw to hold the bars from moving? Might be easier to just drill it and put a pin in there.

That would be drilling through the bars...not sure I would do that.

You could remove the risers and take them to a reputable independent mechanic or machine shop, they would fix you right up.

Absent a shop you can also knurl the handlebars so you don't need that screw. Lots of hits with a center punch and tighten the clamps properly, your bars won't move.

HeliCoils are easy. If I'm understanding correctly, the lower part of your riser is stripped out? Remove the bars so you have access and do as in the video posted by Dan

The bars are knurled. Its the clamps on one side that won't tighten all the way.

After looking at it a bit more, it seems like the internal threads down in the lower riser are ok its just the internal threads near the top of the hole that aren't holding the bolt, so the first thing i'm going to try is slightly longer bolts.

Thanks everyone for the reply's.

14" apes on 4" risers for a 96 Springer. The apes would slip on big hits and the bolts to clamp them down were stripped and / or they were about to be stripped. Went with time serts vs heli coils. Was worth the time and expense and did it all in the garage with a drill press and a vise. Also used a punch and hammer to knurl the inside of the lower risers and the inside of top clamps of the risers. 8 K on them now and they have never moved no matter how hard the hit. Hope you get it fixed and get back out riding.

I don't believe longer bolts will work for very long, you no longer have all the threads to hold the tension. Helicoil or timecert is the correct fix
