I would say that's not normal.
Ya might want to remove some of the aluminum if crank is in there correct
I wouldn't start it up if it was my engine.
it kinda looka like the crank is pushed to the left.
Is the sprocket in the center of the tunnel?

You'll need to get out your measuring device and check the distances of the assembly.
Possibly the crank was pressed to far together.
Good luck.
www.biker.net has manual where you can find the correct measurements for the crank

We also have a crankshaft thread, where we're collecting/gathering/posting info on crank rebuilding, dimensions, problems, with links to other threads. Worth a look:

Thanks for the info. I hate to have to open the case again.

You don't have a choice!
When rebuilding always remember to double check everything.
Even the work of the so called professional.

With the spacing being uneven between the 2 middle flywheels, I would assume that the bearings may not be fully seated in their proper location.
The "Large" outer bearing, it has a snap ring on it. If that bearing hasn't been fully seated against the crank, with the shim behind it, with the large snap ring in place, and then the primary gears properly tightened up BEFORE installation, then the crank may not be aligned properly.
Let me know what you find, but I would check those things first.

Also, the amount of space around the left middle bearing in the picture makes me believe that the crank may not be aligned properly in the crankcases. Just another thought.

Thanks for the replies. Looks like I will be pulling the cases apart and trying to figure it out with the above suggestions. By the time I am finished with this bike maybe I'll be pretty good at working on them.

Yes that's the case.
At least it's one of the easiest bikes to work on.

So an update on my crank rubbing issue...
As suggested above, I didn't have my primary gears installed. I placed in the crank, got the bearings lined up and seated and just figured the primary drive gear, drive gear, spring washer and such could go on later. My newbie mistake. Without these the crank will slide left to right almost 1/4 inch even after the cases are bolted together.
"Happy Dan" from Pandemonium choppers helped me out over the phone. We, and when I say we I mean he, figured it out.
So I believe I split the case again for nothing. I'll chalk it up to experience and I appreciate all the help. Maybe this will help someone in the future.

The real PLUS is you noticed it and did something about it before any damaged occurred.
Congrats!!!
Merry Christmas
