Bike is pulling to the left

[Frasse]

Hey,
Bike is pulling to the left after a steering head bearing change. Without forks the problem is not that easy to spot, it runs smooth without pulling to any side. When the bike is on the centre stand with forks and the front wheel is added it pulls immediately to the left.
I guess the weight when the forks and the wheel is attached causes the problem to be more visible.

- The cables doesn't seems to be the cause of this
- I cannot spot/feel any visible damages on the bearings
- Changed place on the front forks - still pulling to the left

Hope to get some tip on what to check!

If the front end pulls to the left when the bike is on its centrestand, that's nothing to worry about.

If the front end pulls to the left while riding, try the basic stuff first:

Right now, if you sit on the bike and look down at the handlebars, does it seem straight? Are the handlebars straight-looking in relation to your fork caps and your front wheel? If not then the procedure in the above video will help.

It would be a mistake to assume the bike is perfectly level when on the stand.

Also the weight is not distributed symmetrically. The pins and spacers holding the wheel are not symmetrical, the brake hoses are unlikely to be symmetrical. The switchgear is different on each side. You may even have a speedo drive on one side or a single sided disc?

So I'd guess it's heavier on the left side which is fine. If the bearing wasn't properly seated, it would get tighter or looser as you turn it. It should move freely to either side without any play and you're done.

Pulling to the left? Fucking woke Marxists....

You have a major problem
It sounds like the left leg of the centre stand is shorter than the right leg or no oil in the right fork.

Basic stuff has been tried as showed in the video, it seems straight as you described Bhud.
The single disc and brake hose along with the speedo is located on the left side. The steering head moves freely from one side to the other.
If there was no oil in the right fork i would think i should see a difference when i switched them.
I only had a chance to go in slow speed with the bike and the pulling did not seem that noticeable, will try this on higher speed as soon as possible.
Thanks for the tips so far, i will keep you posted. Also had a friend checking this who said he thought this was not a problem but simply because of the weight being on this side.
Hopefully im just imagining it did not pull this much before the steering bearing change, going on a higher speed will hopefully give me an answer

Have you ridden it without your hands on the bars? It should go in a straight line unless you lean to one side.

Jaffa knows nothing about bikes, btw.

It's probably the fact you have a newly fitted nice and smooth oiled bearing and it moves with next to no friction that it didn't do on your old crusty bearing for at least the last few years.

So wait, am I misunderstanding this?

You put the bike on the centrestand, and the bars drop to one side? That's the ONLY symptom of this issue?

If that's the case, there is no issue, get over it and get on with it.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Many mainstands lean slightly to the left anyway to reduce the risk of the bike falling away from you as you put it on the stand.

Thanks for the help guys! There was no issue with the steering head bearing´as many of you pointed out. Had it examined and now i have another set of problems (posting in a different thread)
