| Lift the bike on a rear paddock stand.
With a 14mm socket, undo the two pinch bolts at the rear of the swingarm.
There should be a large C spanner in your toolkit with a flat box section handle.
Hook the C spanner over the castellations behind the sprocket and turn the hub anti clockwise to tighten the chain, clockwise to loosen it.
It's important that you don't go clockwise to tighten!!!
25mm is a little, IMO, tight, I adjust so that the chain just slaps the underside of the swingarm with little force. Turn the wheel and check at several points on the chain so that you don't tighten it on a tight spot!
Once you've got the tension correct, tighten the pinch bolts to 33Nm.
Tighten one down, then the other, then go back and check the other is up to torque.
Don't overtighten these. They don't need "3 grunts". You can fracture the swingarm if you over do it............ |
