Front sprocket removal

Can someone please tell me how to remove my front sprocket. I attempted it and it was turning the transmission. I tried with the bike on the ground and on the stand. I think I was in second gear while doing such. Is the sprocket reverse threaded or something?

No, it's not left-hand thread.
Try 1st gear. The gear reduction is more to your advantage.
Try to use a hammer and whack the wrench to effect short sharp spikes in torque. Barring that, an air impact wrench would be preferred.

I plan to die young, as late as possible.

get someone to press on the rear break always works for me... and use a quality socket or you will strip the head.

You must not be very coordinated. It worked fine for me.

What

40 lbs of torque shouldn't be a big bear in the woods. Impact wrenches are for lug nuts on a truck, not 40 lbs. If your friend holds the brake and it still won't bulge, get a membership at the health club. I doubt the factory torqued too much.

I ended up using a 15'" breaker bar and put it on the nut. Sat on the bike holding front brakes and pushing rear brakes while the bike was on the stand in first gear and left leg on the ground. Was able to break it loose.

The shop that put the sprocket on put it on tighter than the recommended torque. I was having problems with the the small ratchet, because i had the bike in 2nd and was not holding and breaks. When I made the transmission turn once I got scared and stopped.

This useful but so wrong. If you are going to use this method. Please purchase a dead blow hammer for this. Or if you can find one, a Brass hammer. These types of hammers will give you the force need to move a wrench. But they won't send a shock wave through the entire system. Ex: Hammer to wrench>nut>shaft>sprocket>into transmission> and who know where else. This is not good for the motor. A dead blow or brass absorbs the impact with out sacrificing the power of impact.
