Getting my fork seal done in Portimao at the Honda shop next week. Regarding the heavy oil how much should go in the fork leg? And what is the
torque setting when putting the wheel back on?

There is a Uly manual above in this forum, however be careful as 06, 07 and 08 model years have different oil levels. Change between 06 and 07 was brought about by a change in spring, the 08 (09 and 10 models I assume are the same level) had bigger fork legs.

You normally measure the depth from the top of the leg fully compressed with no spring after pumping it a dozen times to ensure the air is forced out.

First thing to do is identify which model year you have.
