Swingarm/mount hole

[THill]

For you guys that have drilled out the rear of the swingarm mount on the motor for the larger KX bolt what did you use to drill it out ?
Large drill bit ? what size ?

Thanks T Hill

The machine shop used a 19mm reamer to make the final hole.

Page 3 of this thread has some info on why you'd use a reamer over a regular drill bit.
