Best source for master cylinder repair kit

[AshimotoK0]

Have a Gen Honda kit for my 750 master cyl but need one for the 500. Anyone know a decent source? Yamiya one would cost me about 27 quid in Japan  but they are sold out. Anyone know a decent pattern one?

M & P do them mate, or any local dealer that uses Hy Level wholesalers

I used the aftermarket one from DS for my 400/4. Described as "The highest quality replacement kit from the original equipment manufacturer in Japan".
Think the same part is used for the 500. Priced at £23 + VAT etc, plenty of stock.
