I'm giving serious consideration to putting some K11 forks on my K100 in order to get better suspension and, more importantly, better brakes. In doing this I want to keep the standard K100 setup with the OEM round headlight and surrounding Tupperware.
However the K1100 lower fork tree does not have the M6 mounting holes so I'll need to add those. I've retapped stripped threads before so am not a stranger to that process but have never made holes "from scratch."
I get that you need to use a smaller than 6mm drill bit but in poking around I see references to using between 5mm and 5.25mm. In looking at my favorite online hardware store (McMaster-Carr) they have 5.0, 5.1 and 5.2mm bits available and I'm leaning towards the 5.2.
Anybody here ever drilled/tapped holes in a fork tree? Advice? Pointers?
