I know you probably already know this, but that type of optimization IMO is reaching, if not past the point of diminishing returns. Cermic bearings are expensive, and there's lots of other places to optimize other than bearings (assuming you have decent metal bearings.)

I have ok bearings right now but isn’t ideal long term but yeah I’ll look into it more.

Why are you using WD-40 on you bearings!?!?!?! WD-40 is a DESSICANT and literally stands for "Water Displacement". You do NOT want to use WD-40 on bearings, you need a silcone-based lubricant. If i remember correctly, WD-40 will actually break down the lubricant on your bearings and dry them out. You want to use something along the lines of Bones Speed Cream

I think the point is to break down the lubricant. The reason? I don't quite remember.

If I remember right, the lubricant isn't important for longevity, no more than we run 'em, but the lubricant slows down the bearing because of it's viscosity. I remember my first Wheeled Vehicle partner's father soaking them in alcohol, though... I've never used bearings, I don't think they would help me enough to make it worth the price when I'm getting the distance anyways...

I used them before adding a lubricant and waited a few hours. I was told to do so because there was a lot of grime on it when i received them. but i guess since you guys said no i will just swap them out.

You should use acetone or lighter fluid to clean your bearings, but de-shield them first. Then, use about a pindrop of extremely thin silicone lube on the bearing, and re-shield. This is how I clean my yoyo bearings. Just look up how to clean a yoyo bearing and a bunch of videos should come up.

This is correct. You can use nail polish remover to clean them, which contains acetone.

A warning about nail polish. If your bearings are small in size, I would avoid using nail polish remover since they have more contaminants than hardware store acetone. Nail polish remover will leave behind oily residue, which is not ideal for cleaning your bearings. Although the impact won't be as noticeable as a yoyo turning at high rpms, but its something to keep in mind.

So I’m trying out the half wingnut breaking system hit the problem is that my wingnut doesn’t flip. It just stays in the same position and I’m so confused on why. Any ideas?
