If you static-time your bike using the method in the
manual, you will need to set the point gap before the
timing, just as you say. That is the way I have been
doing it, though getting the gap precise with the
distributer in the engine is iffy, in my opinion. But
when I timed it while trying to diagnose the problem,
I just put a test light on the place where the
condenser wire attaches, and put the #2 cylinder to
the 10* btdc mark. The light lit if perfectly on time,
so I assumed the timing hadn't gone wacky.
Unfortunately, when doing timing according to this
method, the timing for the #1 cylinder is set
completely by the point gap, and I did not check that.
Bad mistake, I know.

But that didn't answer all the questions, because my
#2 cylinder was actually running worse then the #1
cylinder, even though #2 was times right. #2 was the
first cylinder to start having problems. I think an
accumulation of factors account for this, but I won't
go into that - to much typing.

But I plan on changing the way I do my timing,
virtually eliminating the problem of inaccurately
setting the point gap. I you make marks on your case
for TDC and 10* BTDC for the #1 cylinder, then you can
set the points to open exactly when that cylinder
reaches 10* also, so both cylinders will be timed
precisely.
