I was looking at a few other cafes on another site and I really like the look of drilled rotors, stator cover and clutch covers. Has anyone on here done this? Rotors- 1. At which point do I need to worry about the integrity of the rotor itself? 2. Anyone have a write-up for doing this? Covers- 1. Are there any draw backs to drilling the covers? Rain, dust, dirt, grime, etc? I was thinking about drilling them out and then using some thin plexiglass inside of them to keep stuff out but not 100% sure about it. id rather have it open (ventilation, aesthetics) but again, not sure if there are any draw backs. Any tips, tricks, advise is appreciated. ---

idk about drilling your own rotors, but i do know that a couple riders on some forums have had their original rotors till about 50k miles also on the cover, my old bike was put down before i bought it, and there was a hole in the stator cover, nothing bad seemed to happen over the 2 years i owned it, but i cant imagine it was good for it, im sure if it needed ventilation it would already have holes, but if you like the look idk what ta tell ya ---

Driling rotors is fairly easy to do. With that said its also pretty easy to mess up a good set of rotors. Not a metalurgist but from what i have noticed most modern day (motorcycle) rotors seems to be made of a mutch harder metal then the old school thicker brake rotors. Potentialy the older rotors could be made of a softer material and that might cause roblems if the rotors all of the sudden become too “holly”. I guess a good rule of thumb is dont go nuts with the drill press. A simpler alternative would probably be to try a different type brake pad. As far as drilling the covers is concerned. Usually its done to discipate heat. For example some of the older bikes i have seen have had the sides of the rear drum brake drilled so as to allow it to cool off faster. The same could also be benefficial to a clutch cover provided that its a dry clutch and not a wet clutch. Drilling a stator cover could also be a good thing but you have to take into consideration that the space between the stator and rotor is usually pretty damn small and if a tiny ass peble managed to work its way between them then you could potentialy destroy pretty pricy part. ---
