I put ProTapers on my '99 WR400F and wanted to re-install my Acerbis handguards. The bit that goes in the end of the bar appears to come in two flavors: 7/8" aluminum i.e. Renthals and 7/8" stock steel. The former is to big to go inside the ProTapers. So I ordered a "ProTaper kit". When this arrived it is for mounting the end that goes on the bars near the clamp. So I am still left with the bit that goes in the bar-end being to big for the inside diameter of the PropTaper bar. Do I need ream the bar out, or am I missing something? Thanks!

If there were anything rubber around to pull off, I would, but there isn't. Next!

I have the exact same problem with my 2008 WR. What size bar inserts kit is needed that is small enough to fit in the inside of the bar? Help? Suggestions?

I had the same problems when i fitted the pro taper bars as well.
The gen-yamaha bar end inserts seem to be longer than most aftermarket hand guards.
I had to get a drill bit the same inside id as the bars and drill in a little further until the inserts and guard ends were flush with the bars.
Been aok since.
