Am I being paranoid?

The service manual says to check it with 2 wheels on the ground, ie on the side stand, I would go by that.

+1......think about it, for example. you adjust chain on centre stand to say,40mm. then you flop bike down off stand and the weight of the bike settling onto the suspension knocks that down to 30mm play. then you ( and possibly a pillion ) jump on, knocking that down to 20mm or even less. now imagine you adjust it on centre stand to spec, but manual says this must be done on side stand...........instant guitar string!! everything stressed to the max...bearings, output shafts etc, and that nice shiny chain just waiting to take your calf (or worse ) off. food for thought i think. ride safe

Obviously you have made up those figures and are wild guessing??. I doubt if you went away and checked one or two people up on a bike and measured the chain slack after a centre stand adjustment.

Now what about the other side to the story?......

So, Haynes recommend that you adjust the chain on the sidestand with the same specs. What if they are wrong? Why do you assume that Yamaha got it wrong? I mean, they made the bike so I think that they would know what spec is best and the way to perform that function....no?

If there was a danger of chains snapping or if chains have snapped in the past because of this inaccurate information that Yamaha supplied, they I think they would have been sued to hell and all those Service Manuals would be forced to be withdrawn. I have no heard of any such thing lawsuits or withdrawal of their manuals.


One thing that I didn't see on this thread that the OP might check, which is the actual chain condition itself? Did he measure it in various spots and measure a section of the links like even the Haynes Manual suggests? Maybe he did and I missed it on the thread somewhere. But I know that my chain is being replaced as we speak as it has tight spots in certain parts of the chain and the slack would be 40mm in some areas and 30mm in other areas. Now if I had adjusted my chain to the minimum setting of 30mm on a slack spot, wouldn't the the tight spot of the chain be a way too tight and make plenty of noise around the front sprocket?
