That's a more specific procedure than I've seen before. The '78-81 manual provides 14-19 ftlbs with no backing off.
Admittedly though, I've never torqued one.

Neither have I. We all know tapered roller bearings win the durability contest. Iām hopeful that proper servicing and installation keeps the ball bearings going for a long time. I rode my XS650SK over 20,000 miles the first year I had it. I lived in Florida and my commute to work was 50 miles each way. The bike was it until I moved to Connecticut. I did not service those bearings, probably not until they failed maybe 20 years later.Admittedly though, I've never torqued one.
Yes, but youāre still referencing tapered roller bearings. What I posted is for ball bearings.When I was taught how to set front wheel bearings on cars it was a 5 step process. Snug the nut good and tight, spin wheel, back off nut until you feel no resistance, tighten nut until you just feel resistance then back nut up 1/8 turn and put in cotter pin.
Reason for the steps was to preload the bearing and then spin it to get the grease out between the bearing and the race then go to zero lash, lastly back it off a 1/8 turn to create a gap that bearing expansion and grease could fill.
When the bearing started to get warm grease would melt and cool the bearing down. I think railroad cars still use this theory of melting grease to this day.
Yes. I need to go through and throw away the races with dimples in them.I don't know why i save this crap.
That article isn't bad...
So, this requires the same shimming of headlight brackets as the tapered roller bearing conversion, correct? The R1 got ball bearings because theyāre faster. The XS650 got ball bearings because theyāre cheaper.
I have not used this set up on a stock XS650 fork (as of yet...) yes you're going to raise the top triple, by maybe an 1/8"?So, this requires the same shimming of headlight brackets as the tapered roller bearing conversion, correct?

I have nothing to add other than I learned long ago why I save this crap.Re;The nice lady in the house hasnāt told me to stop,Yet.I like how Yamaha 'splained things in 1970....

They thoughtfully don't mention you will have to undo much of your assembly to change the setting....
I tend to be Mr. get r done on special tools, but since I started using this old race welded to 8" of pipe with a "hammering" plate welded on the other end

to FIRMLY set new races I've seldom, never? needed to reset steering nuts after riding.
When the tone of the blows changes from thuds to a ring, one more time around and call it done
