Cool Wilber 641 Install on '18 f

Installed my Wilbers 641 over the weekend on my 2018 f . From start to finish it took a couple of hours (worked slowly).


Started by removing side panels and right rear fairing. Placed bike on ABBA stand so the rear wheel is off the ground and swing arm is hanging free.
Placed my pitbull behind rear wheel with chocks so I could easily raise the swing arm as needed.
Removed rear brake cylinder, loosened exhaust bracket (Arrow exhaust - so lots of room) and removed the 3 bolts from the cush rod, bottom of shock & top of shock; and shock then dropped right out. If you have OEM exhaust, it may entail removing part of the exhaust.



Installed the Wilbers by lowering the shock in from above the swing arm; and running the reservoir out by the rear brake cylinder and then to the back of the bike.
Bolted the up shock and cush rod & torqued to spec.



Installed the reservoir to the UNDERSIDE of the the seat latching mechanism; re-installed the fairing and presto - all done.



Did have to spend some time adjusting the SAG; and will re-check it in a couple of weeks.

Yes, with stock headers youíll need to remove them before dropping the shock.

I did the shock swap before the arrow headers and regretted it. Get the new headers on before the shock. Or at the same time.

I'm waiting for my 641. I had a 30mm shorter 640 with remote hydraulic preload adjustment but unfortunately the factory had a person who got things wrong twice on spring rating. He's no longer at wilbers. So traded it in for 641 std lenght and I'm going to use lust lowering triangles as I'm short leg length. I was hoping someone had mounted the reservoir for high/low adjuster underneath like nitron or k-tek. Thats where I'd prefer to mount it on left side nr rear foot rest hanger.

I changed the rear shock on mine and didn't have to touch the stock exhaust?

More cars and bikes over the years than I should have done!

Question for you guys with the Wibers 641:

What do you do with the tool kit?

Thanks

Neither did I. All you have to do is take the links off and move the swing arm up and down to get the clearance to fit the new one and itís in. The only thing I had to think about was removing the rear brake reservoir to remove the top bolt.

Did you remove anything to feed the nitrogen reservoir up under the rear seat?

When life throws you curves, lean into them.
