Tapered steering head bearings

Installed the tapered bearing kit into steering head of my 2104 Triumph Thruxton. When torqued to remove all play, there is perceptible resistance when the steering head is being rotated (without the forks) just before and just after center. When I slack off the top nut on the steering stem so that the stem is hanging on the top bearing and turn the bottom tree I can feel the resistance. When I push the tree up against the bottom bearing so that the top bearing has no weight on it and turn it, I feel no resistance and everything turns smoothly. This leads me to believe something is not right with the upper 99-3520 bearing. I have cleaned and repacked bearing with synthetic bearing grease twice and I get the same result. I cannot see any obvious damage on the bearing. I am reluctant to put the forks etc back together if the issue persists and I have to disassemble it all to find out what the issue is. When I bought the All Balls kit I found positive reviews but now when googling for problems there does seem to be some issues in quality. I am trying to get the bike as stable as I can and thought this would be a low cost improvement. Any tips out there folks?

I know this does not add anything to your issue but - The last time I bought All Balls bearings was my last. They are made in China and I was very disappointed in the quality.
It sounds like you have trouble shot it - Next I would call ABB and see what they have to say.

I can't find the thread tonight, but I think I remember someone replacing the originals with Timken tapered roller bearings. Gawd I hope I'm not embarrassed to find in the morning that I'm wrong, but even so they may be able to fit a set. Top quality stuff.

Yes I also remember that but have not found that reference either....

Rotate the bearing 1/4 turn. Does the tight spot move? If it moves the bearing maybe bad...If the tight spot is still in the same place the race is likely not seated correctly in the bore. Coincidentally I am in the middle of doing the All-Balls Conversion right now. I am just waiting on the race removal tool.

I will pop out race to inspect but all looks good from the outside. Race is evenly seated, I made sure of that. I attached a pic of my race removal tool, a large spiral nail, it works great!
