My old dad explained it to me perfectly about 50 years ago. With the front of the bike jacked up until the front wheel is off the ground, tighten the steering stem nut until there is no play in the bearings, but leave it loose enough that the steering will fall from side to side under it's own weight.

To check for play in the bearings, grasp the fork legs down by the axle, and pull/push vigorously, you will feel clunking if the bearings are too loose. To check for damaged bearings, hold the handle bars and slowly turn the steering from side to side, you will feel uneven movement and graunching if there is any wear or damage.

There is nothing worse than steering head bearings that are too tight. When riding in a straight line, the bike will start a slow weave that you will find impossible to stop.

Glad I read this after looking at the Haynes manual. MY 16ES started to wobble between 35 and 50 mph with hands very loose on bars. I'll try re-torque and see if it helps. Replacing bearings is out of my comfort range .Going to get the socket instead of the wrench. Don't understand all the math . My simple mind figures the torque wrench at 90 deg to the offset wrench it gives equal force to both sides of the fastener .The bolt would not know the difference compared to a socket placed on top . Going with that. Not debating wrench vs socket ,just appreciate all the input so I can learn to work on the bike myself .

There is no math. You are never to apply side forces to bolts, side forces cause wrenches and sockets to slip and strip bolt heads. With no side force it makes no difference spanner or socket. No difference the angle of spanner.

Simply use a 3” or 6” socket extension and you can not apply side force to the bolt.

I have the spanner but would rather have the socket. Spanner works perfectly fine for about half the cost.

But totally honest: if I didn’t have either I wouldn’t hesitate to use a large pair of slipjoint pliers and guess.

Wish you luck on your wobble. Less than 1 in 10 have claimed success tightening the ball bearings after the wobble appears. Your best bet is to tighten before wobble.

...and that's the way I've done it on my FJR and previous bikes for years.

I'm aware of the FSM procedure but have just done it this way and then re-check it a few hundred miles later.
I don't know if I ever had the mid-speed decel wobble before or after the bearing install (I guess I just keep my hands on the bars).

I have both and before getting the crenelated socket, I had no issues with the spanner. I cook BBQ better with a temperature probe than when eyeballing it. Same with using real torque wrenches instead of seat-of-the-pants guess work.

Ridden wet. Put up hard.

Mr. BR
I think it a good idea to seat everything with that higher torque (37) back it off, then retorque... but 13 isn't enough. It will let forks fall free, but... it's imprecise... may have to do it again later.

If you go back to older bikes' FSM's, one needs a little drag, some even gave a pull-scale recommendation. Others have torque recommendations at 16-18 ft. lbs.

So, in my opinion, Yammy missed the mark a little bit, a little snugger than 13 would keep 99% of us happy. Most definitely I'd retorque at the first service on a new FJR, or even 200 miles in... seems the vast majority finds them loose/wobbles. We don't want to go too long with loose ball bearings, they get damaged.

I had the wobble on my new 2019 FJR at 1,000 miles. Torqued up the steering head bearings to 16nm using the castellated socket. Wobbles totally gone and you can take hands off the bars for a second or two and it stays steady.

I have both the socket and what the OP has posted. I used the socket to seat the bearings then the OP tool to set at 17 ft lbs then put the socket on and the tq wrench did the click. Guess when I check them later I will tq with the socket 1st then see if the wrench turns it more.

Yes, if you catch it early you stand a chance of remedying the problem with simple bearing preload.

As to the proper preload/torque I find there is about 1/4 turn at the designated 13 lbf-ft before 14. So it is really hard to reproduce the same thing twice. That is why I say if you don’t have the tool then guess with slipjoint pliers.

If too tight you will not like the steering at 60+ MPH. Will be constantly making corrections, over corrections. Hard to ride straight. BTDT.

Having trouble getting the socket. Emailed a couple sites as the did not specify and don't want to buy the incorrect one. No reply from either site. Is the YU-33975 wrench good for all years?Mine is a 16ES. N4HHE I'm just hoping torquing takes care of it but won't be suprised if it does not. Picking up a 36mm socket today .
