I just stumbled upon this and almost couldn't believe my eyes:
http://cgi.ebay.co.uk/bsa-a10-super-rocket-alloy-head-/190552238231?pt=UK_Motorcycle_Parts&hash=item2c5dcc6897I had bought this very head off ebay UK late 2010, advertised as "Super Rocket Head".
In fact it is a 67-1122 Shooting Star head, with the larger Rocket ex valves (67-967) botched in (ex valves are larger than the inlet valves now!!!), on at least three thread inserts for the rocker box the alloy has cracked badly, and there's some bad fin damage.First the seller (located in Thurso/Caithness, Scotland, ebay name was "baraliz" followed by some numbers I think, but can't remember those) delayed shipping, then ended his ebay membership while the item was on it's way to me. He never replied to any of my emails. I had to apply for paypal buyer's protection and pay for an expert's report for paypal as an evidence to proove that the head is unusable and the item description was wrong, before paypal allowed me to return it and finally I got my money back in March 2011.
Obviously he is now using another account and trying again, now he MUST know that the head is dodgy after all the hassle!!!
I have attached some pics I took when I had the head. He has given it a bead blast in the mean time, but it clearly is the same head. Even the left spark plug with the bent tip is still in there!
This head is not suitable for an A10 without extensive modification, and imho isn't good for a 500cc as well with the ex valves botch.
SO BE WARNED!!!!
P.S. I have reported the item to ebay and informed paypal, but I doubt they will do anything before it ends tomorrow, if at all. So once again, please watch out guys!
