Cheers Weeksy but should be OK.
I've stripped down the tank & fuel lines etc a couple of times on my 996 so I guess the layout is much the same.
Anyway, I sold my Haynes manual to Jody last week so we should be able to diagnose if not fix the thing - hopefully!!!
BTW thanx for the recommendation for RideInTyres - I have spoken to Mike & Tyreman re: the BT012SS - pricing came out much the same so I'll have to choose who will fit them. Seems your name carriers a bit of weight round these Ducati fans
Thanks again - if anyone is out this weekend (Berks/Oxon) I should have them on and we can discuss further the merits of which tyre etc
