Tell me "how to" remove front sprocket - Yamaha FZ6R Forums - International FZ6R / XJ6 Motorcycle Community Forum

I have it down to the 30mm bolt holding on the small sprocket. Can't get it to loosen up without the sprocket rotating...what am I doing wrong?

what you need to do is to stop the rotation, i have yet to fiddle with front sprocket on my xj6, but have done many on other bikes over the years. the way i do it is to use a piece of softwood (lumber) placed in the back wheel to stop the wheel rotating (jammed against a spoke and the swingarm), be careful not to damage the wheel!

If you have an assistant get them to hold the back brake on instead.

obviously this requires the chain to be in position.

ps putting in it gear will add additional resistance to rotation.

Back brake is the only way I do it.

thanks guys! i thought that may be it but since i had already taken the back sprocket off i was hoping there was a different way.

is the front sprocket nut reverse threaded or are there any little curve balls to look out for?

Impact wrench will do it to.

Not reverse threaded,but the edge has been pinged down to help lock nut in place,dont worry about that just remove nut, I put locktight on threads when i reassembled,also be sure to put sprocket on with raised lip facing inward(if your using a driven sprocket).....

thanx for the tip about the raised lip also

Also what is the purpose of the metal pieces that fit inside the end of the swingarm tube on both sides of the tire. They seem adjustable with the 2 little nuts and long rod (haha sorry) that are in the outside

those are used to adjust the chain and it is important that they are equal spaced on each side. (see marks on each side).
