Yes I did drill holes. I’m annoyed because I made them slightly too large, and as a result the controls can wiggle slightly on the bars. It’s not noticeable in use, and you couldn’t tell looking at them….. I know it’s there.Thank you for the reply as I just ordered stainless steel braided lines for the front and rear. Non-abs as well so will make this a lot easier. That being said did you drill out holes in the bars to for the notch in the electronic controls? Once the lines come in can eventually hook everything up bleed the system and start making adjustments. Wish I didn’t locktite the bolts so soon. But shouldn’t be too much of an issue loosening to adjust them as I didn’t go full send on tightening them down.
