Default Removing front sprocket nut?

i cant undo the nut on the front sprocket

I've got 130lb going through the windy gun = that wont budge it

engine locked + dad sat on the bike + my foot on the swing arm as leverage + all my strength = still wont budge and the bike is being lifted off the ground

i cant make it out i was the last person to change them but i didn't wrench up that tight

anyone got any suggestions? im completely stumped

I did Andy Saxons the other night. didn't bother with the windy, Breaker bar on and off it came like a good un. Resort to every day tools. It doesn't need impact, just torque.

Lefty loosey???

I know stating the obvious.

Whilst Andy's came off with just his foot on the brake. I have in the past had to put a piece of wood though the back wheel when I have been on my jacks to crack the front sprocket nut.

yeah that's how I've done it in the past, this time round the chain is so badly fubared I've got the motor locked from the generated bolt as the chain just jumped on the sprocket
