Blasted forks.

[Dirk66]

My gs1100e which is aUS import had quite a bit of play in the fork sliders, someone had previously restored the bike on stripping them down I found a lot of grit in the sliders so I think someone blasted and powder coated them and didn’t clean them out properly, anyway the whole lot is knackered. So I need to replace the whole lot. Now I understand that it is possible to fit bandit 1200 forks, but what is actually involved and can I retain the 19 inch wheel but fit the bandit discs, do I just need to swap the steering stem over and can I retain the gs1100 top yoke so I can use the original ignition switch mount and clock mount or do I need to have custom yokes made.
thanks in advance,
Rod.
