Yes. No. Maybe. No.
I had the same sort of problems with my ST on pickup < 10 miles. Drop to the
peg then head for red.
It turned out to be a bad sender unit. Dealer pulled one from another ST and
all was fine. Prior to that
he had tried bleeding the air from the system with out success.

Seems most mechanics feel it is a bit conservative and suggest pushing it
harder. This is the first
I have heard them recommending taking it to 8K. If you stick to the tank
break-in you won't be doing
any harm. It'll just break-in slower. It's your call.

Usually the mechanics will say to run it in a little longer than the 500 miles
before the first check up also.
