Std exhaust silencer weight

[His Dudeness]

:agree
My Fazer FZS600 hardly makes
any noise, or clunk going from 1st to 2nd, but, I do get a clunk when going into first from neutral, especially when going into fist with a cold lump, I find slightly easing the bike forward with my tootsies helps to alleviate this.


Chain tension is important, this is one of the reasons you need a centre stand, spin the rear wheel by hand checking the chain tension on the lower chain run directly under the black swinging arm chain guide that is on the top at the front of swinging arm, and make sure you have 1.5 inchs of movement pushing the chain up without excessive force. I understand this is the accepted measurement for a 2003 FZS600 Foxeye.
See photo of manual.
Although I have read somewhere that the chain adjustment should be made with the motorcycle on the side stand, so that some/most of the bikes weight is on the suspension.
I have always done mine on the centre as its easier to adjust it with the rear wheel off the ground. 

That clunk when you knock it down from neutral into first can also be caused by worn cush drive rubbers in the rear wheel. As the rubber wears it creates a bit of free play between the rear sprocket carrier and the wheel and you feel it as a clunk. You rocking the bike forward might be taking up the gap. You can check if there's any play by grabbing the rear sprocket and rotating it clockwise and anti clockwise.
