LukeG:
I'm curious about that too. I pulled out the 250 cases on the weekend to see what size the holes were, about 4mm, so I grabbed a lathe centre drill and counter sunk the tops of the holes then used a 6mm drill to open the holes up then using a die grinder chamfered the bottom of the holes to blend into the castings better.
What's the oil passage grinding being done?
Thanks
Luke

I use a 6mm drill then a low speed countersink.
I only do this with the KX500 and some older KX250's.
The KX250's I forget what size I use but it is the same as the newer KX250 cases.
