Easy, , see below where i answered Gerald. Its about drilling holes in brake lever. Do what you want with rotors brakes whatever, i never mentioned removing rotors, but letting pads open up lsr guys do. You do not want brakes dragging trying to go lsr.

They drill the brake lever, it will depress by itself if you dont drill it when land speed racing, that picture and dial indicator shows what happens, most land speed racers are already aware of this. I didn’t do this last time and with that big ole brake lever im pretty sure it cost me. Drilling holes allows air to go through and not push lever in applying brake pressure. Its a good tip, just like them adjustable gears.

Perhaps affected at over 300mph.
Hard to believe an affect at under 200mph.

I've drilled both my clutch and brake levers on my Thruxton R. Additionally I pulled the brake pads away from the front and rear brakes.

If you watch my 2021 run vid below you can see pumping the front brake lever a dozen times before anything happens. It's a bit tricky if you get excited pumping the brake lever and get too much pressure and you go down fast at least on salt.

We got 151 mph on a 100 rwhp Thruxton R so it certainly didn't hurt. I ran another bike besides the Rocket 3 without front rotors and calipers which worked out fine and got 140 mph out of a 85 rwhp Triumph. I did plumb the front brake lever to operate the rear brake to make loading and unloading easier.

Thanks for the explanation, never thought about that.
