Yep no washers. Locetite green on the threads. No
oil, in fact rinse everything down with carb cleaner so the loctite actually works. Loctite red is way too miserable to get loose down the road.
Seems a little nuts but the flywheel bolts have an ovesized head and the aluminum is tougher than you'd think.
If I remember correctly Joe told me they use loctite blue on theirs with no problems.
