Why do you need the lock if it latches and you can still open the flap. I would rather not have a lock just a push button to open.

simple short term solution, stick a piece of tape over the lock mechanism to exclude the dust water etc. petrol cap without lock but with flap is UK pounds 45.00 + freight at motobins that would be a cheaper way of getting a flap for your existing cap, they also have 2nd hand parts, maybe they have a cap complete at a good price.Otherwise try some of the German sites as they also have 2nd hand parts.Don't forget the chaingang web site that is for F 650's.

Thaks for your reply.  To answer your question.1. The flap that is broken is aid keeping water and dirt etc out of the key hole and lock.2.  I would like to keep the bike complete and original if I can.Cheers,

I'm with you it would bug me no end to have look down at a broken part on any any motorcycle  Phil
