where the heck do i find a 2mm drill bit? went to the local hardware stores and no one carries them...

If you look on the package of a standard size bit, on most of them under the bit size it says what the metric equivelant is. In other words there is a standard size bit that is the same as 2mm. I can't remember what size it is but just look on the package. one of the standard sizes = 2mm.

well i think a 5/64 is close, but i would imagine something like this would have to be dead on......?anyone?

My advice is correct. That's the way to do it.

i believe the closest thing IS a 5/64, i believe it is less then one thousandth of a difference, but this is just to enlarge the hole that delivers the oil to the cylinder so "dead on exact" isnt needed, but "damn near close" will work, so i will go with your info, thanks!

5/64ths will work fine, i used that same bit on all 3 pumps i've put in

It dosen't have to be installed 'perfect'

once you see how small teh stock oil hole is, you'l know that anything bigger is a HUGE help!

i drilled mine out a little oversize because one of my friends works for bbr and he said that a 4mm hole is what they use in the mini moto sx bikes
