Steering Head Bolt Size / Adjusting

Hi all.

First off, anyone know what size the steering head bolt is? My "Kawasaki" sized socket is too small. After that, I assume there are no model specific idiosyncrasies for adjusting the steering on the 919, right? I have the wobble now.

So loosen bolt, use spanner to tighten below top of triple tree. Light touch always. Still should turn freely from stop to stop. One bounce method. Then tighten the bolt.

Thanks

Sheesh! Gonna go broke buying all these sockets! Anyone says 34mm and I'm outta here.

Maybe I'll just buy an oversized crescent wrench and just strip the hell outta it...

Just got to the cheap tool store (aka Harbor Freight). You can pick up a single socket for a few bucks.

Using the coupon and a sale I got a whole set of "impact sockets" for around 25.00. Surprisingly they are a pretty good socket set!

I did about the same thing. Can't remember the cost, but I purchased a set of deepwell impact sockets from HF for this kind of thing (steering nut, fork caps, etc). I took a grinder to one of them to make a castle nut tool.

Don't remember the size, but I remember putting a nut on from an RC51 SP1 because it looked better




Tightening those locking nuts is a little tricky and rarely does using the service manual torque spec end up being correct. You have to account for additional forces being applied when you tighten the stem nut too. Theoretically the stem nut on top of the triple clamp does not affect the double collar locking nuts below the top triple clamp, but anyone that has ever installed a top clamp will tell you that is bullshit and there is some guesswork involved in getting just the right amount of tightness to it so that the end work is just right...

The rule of thumb on the steering is that with the front end suspended so that the front can swing freely side to side you want the steering to swing just free enough that it can go lock to lock with just enough resistance to keep it from banging on the steering stops. If it just flops all the way to one side or the other on its own then it is too loose.

This. It can take a few tries to get it right.

Don't know if it makes a lot of difference, but I also disconnected my steering damper so I'd get a better feel for the movement while torquing the head nut. Assuming you have one on the bike, that is.

thanks for that, tightening the stem nut definitely affects the locking collars.
its voodoo.
