O2 sensor threads - continued

[George A. Siambis]

I followed list advice and rode my bike to the auto store yesterday and
picked up a spark plug thread chaser (14mm/18mm) for about $8.  About an
hour and one skinned knuckle later, I had only turned the thread chaser
about 2 threads into the exhaust hole.  I'm trying to keep the chaser
straight but it is a bit wobbly until it tightens down.  Apparently, the
siezed O2 threads are not giving up too easily.  Will try again either
tonight or tommorrow afternoon.
