5.5" wheel in GSXR750F

[Iced Lightning]

Hi guys, I have a 1985 GSXR750F with a '92 1127 'R' motor fitted. At the mo' I have a 4.5" GSXR400 rear wheel fitted with 160x60x17 tyre. As this tyre size is getting more difficult to find I'm looking at fitting 180's on a 5.5" rim. I have what I think is a Bandit rim but the sprocket carrier is way too far out. Can anyone tell me what I need to correct this? I have the 'silly' thought that the engine and wheel centre lines must remain in line so the GSXR1100N sprocket carrier would do but I'm not sure.

I have seen/used gs500 twin sprocket career on a gsx1127 rear wheel, also used a gsx1100f on a gsxr (5.5") wheel but don't know about a b12 wheel.

Hope this may help some how.
