Bonneville America Forums Forums Technical Forums General Tech Help - Handlebar mounting.....

A friend bought a set of bars that are NOT knurled, & they slip when mounted. Any suggestions on something that will hold them stable??

Plumbers thread tape worked for me on a different bike, it basically just gave more clamping force.

My buckhorns were not knurled either. I center mocked them up and used a marker to 'see' the edges. Then scuffed the bars and inside the risers. They have not moved since...

Hmm... I told him to try some emory cloth, but your idea might be better !!

If I remember correctly, I used a course flat and round file and then squirted some silicon in there to seal the metal. Went well inside with the files and cleaned up the silicon after. There's no way you could tell I did anything without removing the bars.

Another good idea, Phil. I was thinking that he could mark the spots on the bars & use a dremel to rough them up.

Dremel would work. Maybe use that for really inside and a file to dress close to where you marked the edges. I used a marking pen which cleaned right off after.
