    Peter,

    I used a pneumatic die grinder with 1/4" shank carbide burrs and sanding discs.

    One lf those toy Dremel's would probably work but would be very slow IMHO

    For the fine detail I used a Foredom Flexible Shaft Machine with small sanding discs. I don't own a dremel

    i use one that looks like this in a bosch industrial electric die grinder, spins at 26,000 or so rpm. can be amazingly delicate.

    chris steadman told me to take out the ridges between inlet and exhaust, but not open around the inlets as such. what i do for the 853 kits is here:

    748 ports seem to work very well at the 850cc level, not sure about 900 something though.
