I phoned TF Tuning (Spoke to Tim himself haha) about getting a 191 eye2eye, 2 inch stroke Roco WC and he sed it's not worth it on the ATX with 8 inch plates.
What he said I should do is drill the holes on the frame about 1/4 of an inch lower down to give more travel with the old travel plates. ("this is what we did for all the racers back in the day" as he put it lol)
The 8 inch plates put too much stress on the shock for a 4:1 ratio bike.
With the new drill holes i could fit a 200 eye to eye with a 2.5 inch stroke.
Um......... what do I do lol! I Don't fancy drilling it myself so i'll have to see if I can drive my bike up there and have them do it.
Haha, he was like "Woah an ATX, hasn't it cracked yet?"
