Hi Guys, I managed to get a replacement starter motor for the missus gk75a, it turns out an early 600 bandit starter will fit. The one i got was from a 1998 model and is identical to the 400 one just more of em about hence cheaper. Hope this helps with anyone looking for one.

a tip to all bandit owners instead of using YTX7 battery install a YTX9 its the same size and backs more punch so your starter wont battle as much and makes winter cold starts less painfull and the std charging system handles the electrics much better
