XT600Z generator

[cathal]

After 3 weeks waiting and a phone call to ensure the right generator was being sent,they sent me a generator so far off the mark,I nearly cried.
It's about 2/3's the size of the original and it's only got the 3 phase wires.
I called the supplier and they said it was the correct part,a G09.
It's not.
Has anyone replaced a generator with one that was the same as the original.
Do I have to get a genuine Yamaha part?I'd nearly be better off I think.
It's a '90 3aj,twin headlight,electric start.
