Blue Smoke Baz has an eBay account — he is user bluesmokebaz.
I have his GT750 restoration DVDs & bought carbs from him. He does good work & is highly recommended.
Likely have his email address if you need it.

Re: 380M rebuild
Not as far as I'm aware as the silencers are different. Might be similar to the 250s?
A 380 is 1.5 250s after all.
