Which rollers?

Unfortunately we haven't managed to muster the intellect to get you a definitive answer yet!

Do you agree with my reasoning that the chain case couldn't have that affect?
If you don't why.

You are extremely smart and I respect your answers.

Ok I can see that but wouldn't that mean that the chain doesn't fit all the way into the valleys of the sprockets when it is hot?

I'm not saying you are wrong but it seems like a silly way to design a chain and sprocket set up.

Actually your answer makes more sense than the primary is expanding..

First, it's Harley, second, I can't think of another way. If I could, I'd be rich! Maybe I'll think about it if it doesn't hurt too much.

The expansion of the case is why the primary chain gets tight.

Now, if the cam chain on an Evo gets tight, it must be removed and soaked in Seafoam, and then discarded....
