Well, due to a lack of response from the original dealer i've now booked it in via Tim @ Southern for a quick check on Saturday.
Tiny little worry though, the original guy I spoke to at Southern didn't know what a Bol'Dor was :roll Tim did though, so that was a relief!
Knowing Don and Andy at Southern Cross, I very much doubt that they don't know what a Bol D'Or is, did you speak to an Italian sounding bloke who is in the sales/admin?
I would put money on them being able to sort you bike within 30 mins, if the fault is as described.
Take a look at Don's racebike while you're there, if it's not out - your Bol D'Or won't be the most precious thing in the shop covered in crud :bling
In addition, you mention that it's 15 miles - I take my bike all the way across London to Southern Cross rather than use the franchised Aprilia dealer who is less than 1 mile from my houes, because my experiences there have been poor.
I also knew of someone who brought their Mille up from the South Coast to Southern Cross as he wouldn't take it anywhere else, and thought so highly of them.
You can always take it to your local bike shop, but you've done that, and it ain't running right is it - so you would have ended up going there twice (if you were to take it back), so 15 miles for 1 trip, doesn't sound so bad?
