Cylinders going up while others are going down in a car engine. 2 going up and down at nearly same time in a v-twin.

I'd think it would be the high rev swing-ability of Sportster pressure that the spring and diaphragm can't keep up with.
I don't know for sure but yeah, the pressure should be more stable in car motors.

I changed the breathers today and found that a fiber washer on the front box was toast.
The middle broke out, got soft and bunched up around the hole and it now looked more like a smaller thicker washer.
The small piece feels much softer than the easily breakable fiber washer that I installed.
Maybe it bunched up into the hole. There was no oil around the bolt from the outside.
These have been re-used several times before, replaced them all today.


The umbrellas looked good to me.
The front was more soft than the rear but both were still flimsy.
It turns out I only replaced the front the last time I was in there, it had 'James' written on it and the other didn't.
But I replaced them both today anyway.

What if I just toss the fiber and use the copper?
Can't find a pic of the newer style bolts at the moment.

Aaaaahhh,
Now I see the difference.
They look like dowdy washers.
I'll have to wait for those but it looks like a better seal.
I'll put it on my list.
