Seems to me that the 04-09 Rockets (standard, Classic, Tourer) maps top rev limit selectable is 6800rpm.
And for Touring, Roadsters the selectable limit is 7000rpm.
If you use the 04-09 Rockets 9000rpm limit map, when you try to set the rev limit lower than 9000, it jumps down to 6800rpm.
Same thing happens the Touring & Roadster 9000rpm limit maps, when you touch the rpm limit parameter, it jumps down to 7000rpm as the max selectable.
Alain made us these maps with 9000rpm as the rev limit, but stopped short of giving us the ability to select any rpm up to 9000rpm. You can have 0 to 6800/7000rpm, or 9000rpm. There is also an 8000rpm map for 2013+ Roadsters, that behaves the same way.
So - long story short - if you want 7000rpm rev limit on a 04-09 Rocket, we will need to ask Alain to provide a 20222-series map with 7000rpm limit.
Apart from the valve assembly issues with going over 7k as per Nev, I'd imagine a set of cams that doesn't peak as early as 6000rpm would be beneficial
