Mine is S/N 503 – one of the last to leave San Antonio. I bought the SkyStar firewall fwd kit same as Jim Fillman and Bill Landucci.
Here is a tabulation of the specs I have:

Regarding the breakdown of serial numbers, This is a note from John Melchert in my archives:
Tim Ribar apparently knew the answer here. Below is an excerpt from a
message he posted to the list 09/10/1999:
The breakdown of the kits is as follows:
AD Series I Pulsars (serial #'s 101 - 474) 374
AD Series II Pulsars (serial #'s 501 - 510) 10
Sky* Series III Pulsars(serial #'s 511 - 565) 55
Total 439 kits sold. AD published that 3/4 of the series I Pulsars were
XP's.

Barry,
Who did you buy your kit from ? ? ? ? ? Aero Designs or Sky Star.
Did antbody buy a kit from Soley ? ? ? ? ? ?

It's also 1200 for the Series III. Not sure if there was any difference in spar design from the II to the III. I know the Series III was heavier, mine came in at 711 with a 912 and a bit heavier for those that had the 914. I can't fly mine under 1200 pounds gross with full fuel, my wife and I and 60 pounds of luggage. That puts it at 1320.

As one of the few AD Series 2 Pulsar owners, I will add that the Series 2 carries a max gross weight of 1200 pounds.

Subject: [Pulsar-Aviators] Pulsar weight restrictions
All the discussion on Pulsar gross weights got me back into the manuals, news letters, and finally discussions with my favorite air craft designer. I know there has been some confusion about this, and if you have a plane that was purchased and built in stages, then this can be very confusing. So, here is the simple explanation.
Early Pulsar kits had a sitka spruce wood spar. Spar caps of unidirectional glass were added to the top and bottom of the spar for strength. On the earliest wood spars, the spar caps did not go all the way to the wing tip. The gross weight of a Pulsar built with these spars is 870 pounds. Latter in the program, the spar caps were extended to almost the wing tip. With that, the gross weight was upped to 900 pounds. 900 pounds is the max for the wood spar. This is exactly as stated by Alan Gill for Pulsar aircraft in the UK.
Later Pulsars had the composite spar and gross weight was increased to 1060 pounds.
Please note, gross weight limitation is solely determined by the spar material and spar caps. Composite wing skins and added glass to the spar sides does not increase the max gross weight.
I have looked in the Skystar manuals and not found the numbers for their aircraft, so will limit my comments to the Aerodesigns kits.
Flying an airplane over it's design limit is like driving a car, with smooth tires, at high speed on a wet surface. You may get away with it, until you hit a puddle, or in our case, turbulence. Turbulence adds G loading, and if you are over design limits, the wing could fail, not a good situation.
Needless to say, this is a major safety issue, and thus my concern. If you have any questions about this, please get back to me and I will try to get an answer for you.
Fly safe,
See you at Oshkosh,
Greg
