Today is a great day for me, I feel very satisfied.
I have spent a lot of time on this steering head bearings replacement. I was very afraid of doing this job by myself, I asked questions on the forum (many thanks!), read and watch a lot of videos and I also have the Haynes repair manual.
My ST has 65K, I couldn't feel anything wrong on the handlebars rotation and I had no play when pushing the fork legs .
I did find very challenging to diagnose the origin of the instability on my bike whatever way I tried to test it (Honda weight test included).
The bike was definitively hard to drive.
I have replaced the steering head bearings last week with a tapered "All Balls", but I wasn't totally satisfied with the results.
The bike was wandering at low speed.
Today I have reduced the torque on the adjusting nut from 8 Ft Lb. to 5 Ft Lb. (maybe less)
It's perfect now!!!!
The bike is stable at high speed, going naturally straight and is not sensitive to truck buffeting or road irregularities, smoothly rounding around curves.
My 2 cents...
My old races don't have any sharp marks but a deep wear path in the bottom of the race, hard to diagnose without disassembling.
You don't really need the special tools and the only difficult part is to remove the lover race and to find the right torque for the adjusting nut.
It's all finger tight or close to!
Fully removing the fairing helps a lot, it's just more convenient for working on the bike.
I made the choice to go for the tapered bearings, I know that not everybody agrees on this kind of bearings for the ST.
In my case, I am 100% satisfied with the results and I just regret not having done this sooner, what a change!
