Wobble

So I pulled off my brakes as I am re-doing the front end on the bike and I noticed that the front wheel wobbles. I didn't notice it before I guess because the calipers were holding the wheel straight with the rotors. I pulled apart the hub and it was disgustingly dirty, rusty and in a nutshell AFU. However I didn't see anything missing or a possbile cause to the wobble in the wheel. I assume that the front wheel with no brakes should spin straight and not have any free play. I am at a loss to what could have caused it. The only thing abnormal I noticed was the speedo reciver being slightly bent. I have ordered replacement bearings, speedo reciever, and other parts, etc. Now I am just curious what the play of the wheel is on other 750's.

Thanks

Mine spun freely and str8. I would say wheel bearings is a great place to start.

is it a wobble or is there play in it? if there's side to side play i'd say the bearings are shot.

The bearings look pretty thrashed in terms of rust and goo, otherwise mechanically they "look" ok. I am going to get the new ones later this week and if that doesn't shore up the problem I will post again.

My first guess would also be bad bearings.
When you get the new ones, even if you're told they are pre-greased, fill them with grease anyhow.
Even pre-greased ones rarely have much in them.

FWIW I have used grease with molybdenumdisulfide ((MSO2) aka MOLY) for front wheel bearing for 20 years or so on my cars and trucks. I would recommend it for the bikes also, as the pressure and heat generated will actually contition a microscopicly thin layer of metal as the moly penetrates it. I have seen evidence that this conditioning will continue to protect metal surfaces for some time, even if the grease is displaced later on.

What about "Green Grease"? I bought a tube for something different but thought maybe I could use it on the bike as well, anyone have any experience with it?

What did you use the Green Grease for, and how long ago? Is it standing up to the job?I`ve never heard of it before and there is no mention of moly, but they say it is waterproof and the video clip shows them greasing a boat trailer`s wheel bearings. If it has been around for the 20 or 25 years they claim, I wouldn`t be afraid to try it.

If the bearings are indeed shot, you may want to check the races as well. I know on a car if you replace the bearings, you have to replace the races at the same time since they wear together. They (the races) drift out easily on cars anyway. I don't know about our wheels though. Just a thought.
