Also when tightening the chain you should have the rider on it. The more weight on the bike the tighter the chain gets... that's all about geometry.

I still disagree with this, as I said in my last post, at least for my bike. Maybe yours are all different.

The slack specification given in my manual is for the bike ON A REAR STAND. It doesn't matter what the measurement is or how tight it is with you sitting on it on the kickstand on a hill during a full moon. The spec is for the bike with the rear wheel off the ground. At least for my bike it is, and I think most bikes are this way.

If you do the measurement the way you're saying, the chain will be WAYYYYY loose compared to the spec when measured in the correct position.

yeah mine is the same way - on a rear stand..

i set mine to 40mm after the 520 chain conversion and after a track day it stretched to 50mm.. so i adjusted back to 40mm..

I had never heard of needing a rider to sit on the bike for the measurement but I suppose it could vary from bike to bike depending on the variance in sprocket distance under riding conditions. Although I would assume the idea of measuring the slack while the bike is at rest pre calculated with any fluctuations the bike might experience with a rider while moving.



I do know that I am not out of my mind though.

Maybe the Yamaha technique is the secret to Rossi's many victories?

Clearly you're doing it the way they suggest Like I said, my statements were just for my bike and how I thought most others were. Maybe less are like mine than I thought.

I find it interesting that they want you to do it on the sidestand... this doesn't make too much sense to me since many folks have different springs/springrates, different sag settings, etc... and especially with gixxers a lot of differing ride heights... seems a lot of variables could influence the reading. I'm just thinking outloud here though.

Like I said though, your bike may be different... and it is!

I'm sure if you follow your manual you'll be all set.

on a swingarm stand or standing up the bike would be the same thing.

Not to start an argument, but they would not be quite the same.

Please... do explain. The only difference I see would be some difference in weight. Otherwise the weight of the bike is still pressing down on the swingarm.
