Many Geo's will have these updates on them as well, since they were given out for free by PE. If you do get a Geo, make sure it has these updates. If you get a Geo+, it would have these updates from the factory.
Quick correction on this.
The GST kit was NOT a free upgrade. This was an $80? upgrade to the Geo.
The GR2 kit was a free replacement part sent to owners as the original Geo prop had some small issues for some users. The GR2 kit consisted of: The
1 x G-R2 Prop Shaft Assembly
1 x G-R2 Inline Piston
8 x Patched Eye Cover/Rubber Grip Screw
1 x Patched Rear Frame Screw
(info straight from the PE tech bulletin.
The GST kit was a new bolt, can and the restrictors for getting the Geo to fire under 250 FPS reliably.
All Geo+ will include the GST and GR2 kits, however a regular Geo with these parts does not make a Geo+ (the Geo+ came from the factory with a different bottom on the S3 Regulator, as well as the thumbwheel for the feedneck. The first of the Geo+ were in limited quantities / colors for World Cup in 09.
