How do i do it ? puttin a 905 cage on a gsxr750.:YEAH

Do i drill from the inside ?
Tape it off ?
What kind of hole saw ??


Little help please

 

when i cut mine i used a circle hole drill bit (2-3"?). to start off though i used a small dill bit till i found the exact center. then used the bigger bit. once you cut with the circle hole bit you can't cut it a again because it has a drill in the center of it for you to be accurate. if you try cuttiing the hole again with a bigger bit it'll just spin off and f up the rest of the plastic. then sanded it smooth. this was my first time doing it and it turned out alright. if you know someone good with drilling or someone that has tools and is competant, i'd let them do it.


oh and i did it all from the outside of the plastic with an 18v cordless drill and a couple of bits.
