You'll have to make the pictures smaller, or smaller file size.
Change the resolution of you camera to 'low' or use a photo posting site.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Tip top. See you've done the sensible front brake upgrade - did you change the master cylinder to the 'D' type? (Look underneath the actual master cylinder.)
If you've used the original one, yes it works, but you really need a m/c from the Gt750/GS750 or similar for better operation and 'feel'.
I fitted a pair of cheapo chinky ones to my 550, but I've got a hydraulic clutch on it as well.

I sold 2 x 3 into ones last year, but one might be available again. I had it ceramic coated and it does last, but the Piper is bloody noisy. I had it on my 550K a few years ago at the Classic but took it off when I got home as it was just too loud.
