For sure on the "sparingly". We like the BLUE gel stuff - stays put. Clean out the holes with a shot of starting fluid and a Q tip - bolt threads too. We probably don't use the tourque wrench as much as we should either, I quess. They will stay put. We try to stay away from the red threadlocker for the small stuff on bikes, although we use it on everything on the trucks.
Don't see much saftey wiring nowdays. Used to be plenty of it though - Cummins flywheels, main drive hubs in Fuller trannys etc. Understand that aviation mechanics still do a lot of it.
D&H, that ol' ironhead sure has your number - keepin' you on your toes - But working on them is half the fun of having one. Right??
Mamacita and me took a ride out for breakfast early - back about a half hour now, and fingers still numb and slow to type. Love it.
