Hebo/bark buster issue

[skid jackson]

I have the stock hebo bars on my 06. I went to put my cycra probends on a new set and the barkbuster insert was too small. old bars are cut down and the skinny bar inserts work fine on them. Cycra does make a fat bar insert. Being impatient I went down to the local shop and picked up some moose fat bar inserts for the moose barkbuster. A fat bar is a fat bar right?? The moose insert screws onto the end of the cyra barkbuster just fine ... Problem is the moose fat bar insert is too big and won't fit inside the damn bar. it is not even close!! WTF is up with that?? Fat bar is a fat bar right?? I guess I'll give cyra a call and see how fat their inserts are. anyone else run inot this issue??
