Hello!
Could somebody tell me the meassures of the speedo washer? Specially Inner diameter and thickness…
Any ideas how to build one? I am missing the original one.
Regards
Miguel

Thank you for all your inputs as always.
I will take the wheel out soon and verify all your infos.
If that is the case the washer is most probably in. I don’t know why, I always thought that there should be a clearance between the speedo housing and the right fork leg (because of a washer) but if the real washer makes the housing surface flat, i understand that the right fork leg is touching the housing?

All of this starts because I have a very strange effect. When braking very hard with the front brake, I would say that the fork suspension is fully compressed, the front wheel has a tendency to swing (more to the right but also to the left) like an unstable feeling.

I thought to start resetting all the fork installation, check the brakes… if it continues, I guess I will have to start thinking about the fork springs…?

I am open to ideas.

It is my freshly restored 3C.

Regards and thank you.

The front axle is bolted on to the left hand (as viewed sitting on the bike) fork slider
The clamp bolts, at the bottom of the right fork slider, should be left loose until the forks have been compressed several times against a wall or kerb (not by applying the brakes).
This will ensure the sliders are parallel, then tighten the clamp bolts.
Job done!

Ok, will try this. However I would be surprised if this would be the source of the problem.

What if the discs are touchingthe brake pads when doing that procedure? Shim the calipers?

There is road camber as well, being as you are riding on the right side the slight drainage falls right and the opposed for left side users. Very early in the ownership of my 3C I had handling issues. What helped a lot was building a jig to confirm the bike was straight and the wheels were aligned as well as I could get them. I made it out of 18mm custom wood sheets, one on each side of the bike, jacked up on blocks as high as possible, up under the bike mufflers and hard up against the wider rear rim, with a cutout around the centre stand. It's overkill but it makes it a dead-easy and completely accurate way to check how straight the bike is and alien the wheels. My issue turned out to be the bike missing that 5mm approx thick 2nd rear wheel spacer on the left side of the bike. It now runs dead straight hands off the bars. BTW all the above posts are very helpful as well.

Yes, very cool colour 👍
Re the braking: How’s the steering head bearings?

They are new and well pressed. That is for sure.

Actually when I ride with 100km/h i can release my hands of the bar, and it will ride just straight, no shimming, nothing, braking smoothly is also ok.

Regards and good morning,
Miguel

I had another set for my sf3, they worked beautifully. I tend to think that if I have installation problems that is my fault.
What sort of problem should i expect?😅

Mine are a bit thick.
I needed to mount worn pads otherwise I couldn't get the calipers on.

Yes, they might be, I can mount them, but woth the pads fulky back the clearance is less than normal, however I can set them without touching the pads, when setting the fork “not properly” as I did, if i follow the procedure that was mentioned here, they will touch on one side with pistons fully back, I am thinking to shim both caliper to avoid this problem. Hopefully this will solve my braking issues. But truth said, i don’t think they problem is the too thick rotors, and I had another pair of rotor from him installed in my sf3 and they work perfectly without installation problems…

Check that your front fender bracket isn't contacting your center exhaust down pipe. Would indicate a bent frame. Don't ask how I know...
