I'm geezer (C10) and non-geezer (flashed C14 with sports suspension).
As for the air cooled Z1000 lump, it is designed to idle and cool itself indefinitely when not moving.
Convection provides adequate cooling but it's gonna get ****ing HOT and I foresee see many many burnt shins/boots using that.
Those tyres are just going to turn to smoke if you unleash anywhere near the full power of that 90bhp motor, let alone if you push the NOS button.
I'd love to have a go on it though! <LOL>
