Spoke to a mate who imports some kits and he can get you a kit that will make an SR50 produce a fair bit more power if you want more info and a price I can find out for you, the race bike im building up is gonna use a fabrizi kit too.
You should consider buying a Giller runner 180sp There is one left in the world thats brand new and it just happens to be in NZ, they are wicked.
