Anyone ever modify the stock plates for straight bars, then bore the mounting plate out a bit to 1" (25.4mm) to fit Mountain Bike handlebars which are 25.4mm mounting diameter? You can get flat bars for like $15, tempered and anodized, sometimes 7075 aluminum. Seems like a better option than just straight 6061 bar. Also LOTS more options on thicker bars (31.8mm for oversized mounting) and sweep/riser setups.
I'll probably give this a go next week, just not sure how to bore the stock mounting plates, might be kind of tricky to rig it up on a mill. Bolt the clamps down and use a big ass 1" bit I guess?
