Aye Ian,
Don't give a toss, the pearl black certainly looks good and the darker gold rather than 'brass' adds to the combo. But it's your bike! As I've said to others "Sky blue pink, with yellow elephants and orange palm trees is fine by me!"
OH! My mono swingarm is bare clear anodised alloy and just gets a wipe over with a bit of wax after a scoosh.
I'm off to play with an AMAL MKII' jetting and multi-coloured spaghetti with a black corroded copper centre!
Sodding 1980's Italian electrics!
Good health, Bill
