Short Chain vs. Long Chain

The big gear vs. small gear got me thinking.

This weekend I had to shorten a chain to run the gearing I wanted. In the past I always ran a 120 link #35 chain. This week I took about 8 links out of it to get it shortened to where I wanted it. I am not sure that it changed performance at all, but I'll pose the question anyway.

Aside from engine placement for weight, is there any benefit to running a shorter chain? Could there be a performance advantage to less/more chain?

In my opinion, there are much better ways to tune rotating weight for inertia, without at least some of the unintended consequences.
YMMV

I can say pretty positively : That neither the small sprockets or short chain .
Low rotating inertia is going to affect our game ...

Me neither.

However, this has been the common explanation for things not understood.

My thoughts on inertia is that you should leave the chain where it falls, and add, or remove chain guides to the gear sprocket for more or less inertia to drive system.
I doubt most will be able to feel any difference.

I'm on record for my stance on the ratio issue. That doesn't change with the "new" information.
