FZS600 USD fork conversion query

There is however the small matter of the deeper bottom yoke, which strikes against either side of the radiator before it hits the lock stops.

Got the same issue on my project Fazer with KTM Super Duke yokes. I think the cause is more likely to be that the offset (pretty sure it's called the offset) on the donor yokes is not as much as on the Fazer yokes. So the forks actually sit closer to the frame/radiator and the trail is reduced. Another reason why I highlighted the possible (negative) effects on handling/stability. I'm designing in the mount of a steering damper on my build for this reason. I may end up getting custom yokes made to replicate the offset of the Fazer yokes.
