I rode my H2-A again yesterday. With 16 bikes in the shed, it only gets out on nice sunny days.
It still surges a bit. I keep promising myself to buy an Ivan’s kit for it, to try to smooth it out a little. But, if I want a smooth ride somewhere, I can take my Z13 or my ‘05 Z1000!
I don’t hammer the H2 super hard, but do like to give it a bit of stick now and then… and then you don’t notice the surging

.
So, short answer, no. Haven’t done much about the surging.
The second disc is a bonus for you! Hopefully that included the r/h caliper. A master cylinder will be easy to get compared to the caliper. It does add a bit of weight to the front end, but I have noticed a decent amount of extra braking.
Purple models were rare in Australia, almost all -A’s sold here were gold. I think the gold looks a hell of a lot better anyway.
