to shange the front sprocket, the easier way is to leave the rear wheel in, then you can wedge a bit of timber through the wheel and swingarm, so when you try to undo the front sprocket, the wheel stops against the timber and you can easily undo the nut. remember to get a new lock washer as well. alternatively, if you have a buddy, he can press the rear brake, which allows you to undo the front sprocket. same in reverse aswell.
