Mine is a Thor, it’ll sit up around 1,100rpm for maybe 30sec before settling down to 700rpm. Some GEMS ones I’ve worked on have been similar. The warm idle on GEMS seems to be a bit lower, around 600 to 650rpm.
I think yours is special! It should still do the magic high-idle when cold though. Perhaps the IACV needs attention?
