Std exhaust silencer weight

[His Dudeness]

As you say we do what we do and all seems to be okay, i've just never adjusted my chain on the sidestand ever before because i want to spin the wheel to hear if it's right or not, so it makes no practical sense to me.
There must be a happy medium somewhere too 'cos i'm no lightweight, have taken pillion before, and also have a large top box which is normally half full of whatever and have never considered adjusting the chain to compensate for the extra weight one day, and the lack of it the next.

I guess they take into account all the variables that can happen when they come up with the 30-45mm limits so as long as you're in that range you're good. If you can get into that 30-45mm range by eye by adjusting it with the bike on the centre stand you're sorted, don't change a thing. If you were putting it up on the centre stand and then adjusting it with a ruler to 30-45mm when you put it back down on two wheels it might be over tightened a bit. But we're probably splitting hairs anyway I just like to look at things from an engineering/maths points of view

The yamaha service manual says to adjust the chain so there is 30-40mm of slack at the tightest point. Here is where it gets awkward though. It says to do it with both wheels on the ground. With both wheels on the ground, how are you meant to spin the wheel to find the tightest point?

Doing it on the side stand certainly does make the whole process more awkward. I just roll the bike back a few times and then flex the chain each time to see if there is a tighter area, then adjust it from there. It adds a bit of time to the process but with regular oiling how often do you even need to adjust the chain so the bit of extra effort of doing it on the side stand isn't a big deal.
