I intend to fit a full flow system and want to get the prep work done while I have the crank cases split.
I am going to use a Gene Berg Kit but need to get hold of a 37/64 Drill Bit, 3/8 Pipe Tap and a 3/8 Tapered Reamer.
Does anyone have access to such things and would like to negotiate a weekend rental. Call me old fashioned but they seem to be very expensive to buy for such a quick one off job.

Living in hope with both fingers crossed
