My bikes road registered, and while I've dumped most of the regulation gear (blinkers etc) I still need the speedo for transport sections. I also don't mind tracking kms, and the 2013 Vector unit hasn't got its own tacho pickup and counts hours while the front wheel is turning. Bit of a poor design really.

The alignment for the hole was real touch and go with very minimal clearance. I did my best to keep as much meat on the outer edge, but at 2-3mm it really is as far as you can go. Any further and you wouldn't get the caliper bolts lined up. Even with the current setup I really need to be careful in getting the lower bolt started and done up and then apply some pressure to the carrier to pull it into position to put the upper bolt in. Snug as a bug in a rug.







Cable is cracked, but was already. This is on the old steed. Everything lines up pretty well. I put a battery in the speedo and spun the wheel up and it was reading so thats a win as well.

Spacers etc


And the 15mm of axle that sits out


So everything is pretty much ready to be swapped over to the main ride, and then taken out for a test run.

Looking good mate.
I will have to ring you and have a yarn soon.
Cheers Mark

Those forks were a good find! mine are pretty nice, but definitely seen some dirt, those look like they brand new

Jake,
I missed what you are doing for the triple clamps?
Did you bore the GG top clamp?

I got a spare GG top triple bored out. Jakes are newer and fit the GG triples

Very first post. The Gas Gas stock forks are a 54mm OD. You can match this with some late model KYBs, however you'll drop 3mm in total offset due to these forks having a shorter axle lug. If you bore out the upper clamp from 54mm/56mm you'll have a larger range of forks to chose from (inc WRF), and depending which years you'll also be able to retain the same total offset.

I'm taking a bit of a gamble by dropping the total offset by 3mm, but I believe it should work well on the 2012+ chasis. Maybe not so well on the older ones which already need a bit more input in the turns.

My speedo never worked so I never got carried away with that.

Couldn't quite get my head around why Steve opted to use a WRF axle over a YZF. He had told me it was too short, but end to end measurements were perfect. Given his current situation I don't expect him to sit around explaining things, and for good reason too! Thoughts with you Steve!

So with some measuring, we'll start with the brake side. The spacer is required to do 2 things. Set the center line of the hub, and align the rotor in the carrier. It does this. Then the hub is a constant, and so is the shoulder on both axles (YZF/WRF). The difference in shaft length is 20mm. Basically, when all is done with the shorter axle the shoulder on the floating side would be right on the seal lip, which leaves very little spacer, and a poor sealing surface. You could get around it a few different ways, but none are easy persay.

I'm guessing best bet would possibly be running with an axle shaft length between the two/a little less shoulder. I may get a mate to measure up a Honda CRF axle for exercises sake.

Is there a reason why you want a shorter axel (other than aesthetics)?

One thing I have noticed is that I cannot see any noticeable "float" on the rhs shaft when tightening up. Not sure if this is because the kyb's are a much tighter package than the extremely wobbly (at full extension) Sachs that k am used to where I could slide the fork bottom a couple of mm either way when trying to get proper fork alignment. Or is this due to the spacer sitting slightly inside the fork bottom?
