I noticed a post about cutting a hole on the heat sink of the axe to open up vent holes. can you just drill a few holes in the heat sink where the vents are or is it better to dremel out a larger hole? If anyone has a pic of the mod I'd love to see it.

And another noob question. I've never had the motor out of my axe or had to do any repairs in the moto area, Does the heatsink simply snap on and off?

Thanks, Stevo
