lol, i drive past you on my morning commute! should pop in and say hi at some point

as for the sprocket

King tony 1" drive power bar, works on all my bikes

Jam something in the sprocket, skidmark works well for this, he is dense enough and doesn't bend under pressure of the power bar.... however his latest honda purchase may have altered his physical coefficients in reference to bending both ways, best just use a crow bar

Oh FFS! Just wire both sides of the chain together behind the front sprocket and turn the fucking nut!

Um. One wee caution. getting that nut undone is going to involve a lot of force. And locking things one way or another. There's a small but real chance something might break (like the chain) , in which case bits may fly around at a fair speed. So please in such circumstances, always wear safety eye protection .

Whatchu talkin' 'bout, Willis? There's no elasticity in a roller chain, and no inertia (since it's not being undone while he's bolting down an enduro track at 80km/h) and the chain would have to be ultra fucked beyond being able to transmit any power to the wheel before you'd ever break it with the torque you could put on the sprocket nut through a socket (that is to say, it'd have already broken the chain through use to turn the rear wheel).

i reckon the socket and man bar will shatter, sending splinters deep into him.

I reckon when the nut lets go he will drive his knuckles into the ashphalt and shatter them, he won't be able to ride his bike and be forced to sell it.

Thats why you use your boot and stand on the man bar...

As for it shattering, i used a king tony 1" drive 2 1/2 foot long T-bar and a wookie :-) 100 kilo westie standing on a 2 1/2 foot strong arm gets pretty much anything undone
