I have had to reface the exhaust port on my number 1 cylinder. The
directions for the refacing tool say I should clean the threads of the
hole the exhaust studs go in but I can not find a tap to match the
threads nor can I find a die to match the threads on one of the new
exhaust studs on the side that threads into the cylinder. The threads
for the flange side are different but both are 5/16. Where can I find a
tap and or die? Thanks
