Front end vagueness & decel wobble

[JohnP]

I've been noticing increased "vagueness" in the front end. This weekend after 750 miles of riding, I also noticed a considerable deceleration wobble. Going down a hill at 50mph if I let go of the handlebars they wobbled back and forth a lot well decellerating. I didn't notice any shake or shimmy as long as my hand were on the handlebars.

Before the weekend I took the top clamp off and checked the top bearing nuts, and they were tight.

Any ideas what I should look for?

Thanks,

John

tire pressure? Missing wheel weight, strange tread wear? steering head bearing?



So many things to check

those are the three I'd go for before taking it to the pros!

Check the forks... are they even in the triples? Same amount showing up top (or flush). Lower steering head bearing? Is the brake rotor warped?

And all of thee above...

I'm going to guess that it's something you did to the bike before you rode it.... if you took the top triple clamp off and reassembeled it, there's a (small) chance, something is amiss in that process.

Other than that, like has been said... look at inflation, balance, fork tube misalignment.... Tire wear can cause a mild hands free wobble at times, as well. How many miles on the tires, now?
