There are a couple of ways of doing it
1. fit a second left fork leg to right side. Looks a bit odd as one caliper is in front and one behind fork leg
2. fit different forks with dual disc capabilities.(Any of larger model CB's, 450, 500,550)
3. fit a completely different front end (Suzuki Katana is eay with minimal welding)
Options 2&3 are best as the stock 33mm forks are a bit flimsy.
Honda 35mm forks work OK but are a bit heavy
Katana forks are 41mm and about same or lighter than stock forks
There are other forks that can be fitted but so far the stock or Katana are all I've done
I've posted pic previously of CB350 drum in Katana 600 forks on CB360
but here it is again
The blue forks are 2002 GSXR750, same length as stock Honda forks
