I just swapped my standard FZ1 bars for Renthal 758s with the intension of fitting bar-end mirrors (which I have already bought). I've chopped about 50mm off each side of the 758s, drilled and fitted them along with all the switchgear etc.; perfect fit.
I went to fit the bar-end mirrors (they are the expanding clamp type and insert into the end of the handlebar), however there is an insert in the bar (recessed by about 25mm) that is preventing the clamps from being fully inserted into the bars. If I hadn't have chopped off 50mm, there wouldn't have been an issue. The insert looks like plastic tubing. I'm not sure what the purpose is and is it safe to bore this out 25mm so I can get the clamp in?
Thoughts anyone?
