The last topend I did on my 200 I had the cylinder measured by my local engine machine shop, based from that info ordered a completed topend kit from Go.Fasters, which was Wiseco. I have put 3 topend in my 200 and have always used Wiseco complete topend kits. The last time I had the topend apart I did rings only, through Go.Fasters.
As far as I know, the 200 motor has NOT CHANGED since 99 when it first came out.
Off the top of my head I am not sure if Wiseco offers a "A,B,C,D" sizes.
Hope this helps.
