I remember a post about this a while back but it didn't come up when I searched:
What's the trick/technique to removing the front sprocket? I read my manual last night and it didn't really say much about it other than using lock-tight and 145 Newton-meters. I remember and know that the tranny must be in neutral to avoid destroying the shift forks and either lock the rear wheel with the brake or a board through the spokes. I also remember that using an impact wrench was advised...
Anything else? What grade/level of lock tight should I use?
