Ted,

If you had the distributor out you could have put it back in 180 degrees
out. Bike will run crappy when and if it starts.

Hi Ted,

If you are feeling suction when you put your hand over the left exhaust
port on the head, then that seems very odd to me. Unless your valve
timing is way off, I wouldn't think that should ever happen.

I'll ramble through some thoughts...

Let me think this through with consideration with the four strokes:

1. Intake - Intake valve open/Exhaust valve closed
2. Compression - both valves closed
3. Power - both valves closed
4. Exhaust - Intake valve closed/Exhaust valve open

Of course, there is some slight overlap, but nothing that I can think of
that would cause that much suction. Perhaps someone else on the list can
provide more insight.

I think you mention that you static timed the ignition, set the points,
tried a new condensor, tried new plugs, made sure the points/condensor
wires weren't touching, all to no avail (please correct me if I'm
wrong).

You may want to re-checked the static ignition timing. John Schwartz
told me a story of a bike he just couldn't get to run right one time. He
would static time it and it would run good for a minute, but then the
performance would deteriorate. He'd check the timing again and it was
off. Drove him crazy. Finally, he pulled the distributor and found that
the spring pin that holds the gear to the bottom of the distributor had
sheared off. I doubt that this is your problem, but when you are at the
end of your rope, it might be worth a try.

This just seems like a timing related issue to me...hmmm...

and noticed something odd, when I put my hand over the left cylinder
header
and crank the bike (spark plugs disconnected), I feel more suction than
exhast, feels like its going to suck my hand into the pipe. Is that
normal?

I have completely and throughly cleaned the carbs, I get spark, wiring
appears to be in good shape I have the aircleaners off currently, gas is

flowing though if I blow into the fuel inlets on either carb, it does
take a
little effort.

I remember when the bike originally began running bad, I noticed my
generator had slipped in its cradle and was straining its wiring, but
the
wiring still looks fine, the gen. light goes out when sufficient revs
are
reached and I do have spark (not sure how strong).

Ted
