well done for spotting your mistake - easily done
a tip for the future in case you take it apart again, no need to drop the coolant, just unbolt the rad & let it drop down - gives plenty of access to see the front cam marks.
and put a roll of cardboard inside the big timing plug hole so you don't damage the threads in the casing when you're turning your 17mm socket, otherwise the plug will be a pig to get out next time!
to make it easier to see the marks, i put some tippex on the flywheel and went over the marks in black biro - much clearer.
i personally find the rear exhaust cam most awkward cos the mark is hidden partly behind the frame, whereas the front marks are facing you.
i'd guess if the gears were moving when you put the cct in, you weren't pulling the non-tensioner side tight to take up the slack.
the slack should be on the tensioner side, otherwise when you set the tension, the gears move, as you saw!
now you've got the nack of taking the tank off you've always got something to do when it's raining - what's next? dyno kit? cams? gas flow? pistons?
