Just to keep down any confusion, Those aren't Lord's specs. LordJim was giving us the factory specs, which, according to him (and just about everyone else) are way too high.
The manual gives Max tire pressure wich is generally way to high for most use. It usually sugested only for when you have heavy loads and are just trying to get from poit A to point B. Now, 30/32 seems a bit low to me but I haven't been on a 51.
The F4 manual also gives front/rear as 36/42. I use 34/36 on the street (I used to use a bit higher but found out this is better through further experimentation)
