Surprised a search on this only turned up two returns...Anyway...Still trying to sort my front brakes to my satisfaction. They're strong enough but they do tend to drag just a bit. Hoping that the new set of stainless pistons might help (the one stainless replacement already fitted is slightly larger than the standard pistons so the others tend to steal all the movement) . If it doesn't I was wondering about a larger master cylinder as I've read the 16mm doesn't pump enough fluid for the six pots. So to the question....Anyone know if a K5/6 1000 master cylinder would fit? It's a radial type but looks to me like it would fit without issue be nice to find out for sure though
