Here some answers:
1. thrust power records....as I wrote before in my long note about FIA and FIM....in 1963 the FIM accept the SoA Three Wheeler record, albeit there was no class or category....
the rival between FIM and FIA created the strange situation.....Tom Green's record was official certified by the FIA as a record (I visit Tom at his home end of the 90's in Schaumburg/Il), also the first record from Art Arfons three days later......more strange was than, when the FIA also certified the SoA Three Wheeler record from Craig Breedlove...
this didn't make sense....where is the fourth wheel....the steering wheel....the FIA turned everything upside down just to have the fastest vehicle on earth in his organization....
this to the rival between this two...
2. FIM, last year the FIM created a new website....before I tried to find information in the old one....there was for a while a list which showed the old (frozen) and the new records....
now the old website is gone....I got the rights from the FIM to go through the whole (new) website, but I couldn't find nothing - honestly....this website is extremely confusing if you try to find something...just to find a rule it can became a disaster....no idea what they thinking.....
Anyway....somewhere in my archive I kept one of this "mixed" list....also I saw two years ago at the Retro Classics at an antic book dealer a copy of an FIM record list book which was from the time when they done the change...unfortunately the prize he asked for was out of my range I could afford......I'm not Bill Gates...
