Had to strip down the top to re-torque the heads as well as addressing an oil pressure gremlin in the timing case.

I learned a long time ago to remove the tank/covers to avoid any self inflicted wounds.

As as side comment (since your knickers are down) that XS reed valve is a looong way from the timing chest.
I'm certain it would work better (lower internal engine air pressure) if it were much closer - or even better be plumbed to the crankcase rather than the timing chest.

Define "better".

I think if you re-read my post you will get the gist.
Why is it there? To lower internal air pressure!
The closer it is to the source (downward piston movement) the better it will work.

Or if you are really after a definition of "better" - read your dictionary - it is under "B"

or - if you're just being a pernickety askhole - ignore the above.

I don't need to re-read your post.

Like Dan, I chose to mount mine there, based on LOGIC, not happenstance, 12 years ago, worked GREAT.

There's more going on with breather than the you care to accept.

Before you commence to name-calling, perhaps you might try to at least UNDERSTAND another viewpoint.

Have it your way then - Jim Comstock, NYC Norton and cNw must be deluded in the placement of their breathers

Ok . You don't show a oil pump rubber seal in the third pic at the output. Could that be your problem?

Dan,
I was looking at how you mounted your Shindengen regulator and wanted to know what holds the battery in place?
Thanks,
Mike

Ponder this one (example) for a while...

For 15 years EVERY motorcycle OEM had air fill fittings on the fork caps. Honda, Kawasaki, Suzuki, Yamaha. There is significant engineering braintrust there.

Then one day the air fittings were gone.

They were gone because it was finally accepted that the benefit also brought with it unintended consequences.

Cost/benefit ratio.

The heard, sometimes, stampedes in the wrong direction.
