Well i went.
And found a plain fuel tank cap cover to fit my bike, unadorned with eagles, chickens and with no meaningless phrases scrolled around outside along the lines of "live to die, ride to the shops" bollox. And all for the sum of one single british pound.
Now to put the old one on ebay and see what it fetches.
Some nice bikes for sale, plus a few beauties parked up.
Duo glide and the green bike were both priced at £12K
