    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

front wheel hop

As I gain speed, the front of my bike starts to do a hopping motion, not uncontrollably, but definently noticable. Do I need to chage my fork oil?

I'm thinking fork oil in most any condition except solid should prevent bouncing of a wheel that is balanced and true. That said, if you don't know how old your fork oil is, it may need changed anyway.

Of course, the wheel is balanced, right? It's the bike shown in your signature? Does the rim run true, or do you need to adjust the spokes?

How would you balance a wheel? How would you adjust the spokes?
Its at a low speed, no more than 35mph
I should change the fork oil anyway, just worried if its something mechanical
 
Hi,

Wobbling and hopping at that low of a speed sounds kind of scary.

I always have my wheels/tires balanced when I get new tires mounted. The shop balances for free, lucky me.

Or you can do it like Mr. brwringer does: Balancing Tires

To true the wheel you'll need a spoke wrench and good eyeballs, adjusting each spoke until there is no wobble or hop in the rim and it is exactly straight and round.

Thank you for your indulgence,

Not being sarcastic here , but if you have to ask how to adjust or balance a spoked wheel , take it to someone that specialises in this black art . It can take a bit of skill and can be easy to balls up .
See if you can find someone willing to pass their knowledge on . Try a restorers club or British bike club . Those old buggers are usually only to keen to help out .
Good luck .
Cheers , Simon . :)

When you change the fork oil, be sure to diassemble and clean the damper rod. If the ports are plugged it won't work :rolleyes:.
