Got the indicators and new tank on. New bigger front sprocket and chain so the gearing is a little taller. Still not running quite right (watch video with sound if you can please)

I’m wondering if I forgot to set the valve timing properly when I threw the engine back together about a year ago, but I’m pretty sure I did ? I’ve got the dreaded wiring to do and have to fabricate a mount for the front mudguard.
I think it’s starting to look quite good for a pile of bits build ?
