Husky TE510 - Is it a headshaker?

Hi,

I'm really enjoying my new (for me) 2005 - TE510. Very happy with most things .....except....twice now on hard acceleration in 3, 4th gears it has been on the verge of a major tank slapper!! Sure did get my attention.

The front forks are as I bought the bike with 3 rings showing thru the top clamp. What is the affect of raising/lowering the forks thru the clamps....will this reduce it's head shaking? Are these bikes overly sensitive to this?

I see that steering dampeners are available for these things but is that the only cure (they are expensive)?

What actually starts this scary handling trait?

Thanks in advance for your help.

Cheers

Have you set the sag on your rear suspension? The Husky's are known as some of the most stable machines at speed, check your head bearings too, hows your front tire? is it at the proper pressure? Perhaps the forks are too high in the clamps, set your rear sag, then experiment with fork height, I have 2 lines showing on mine & never experienced any head shake.

P.S. was the previous owner much heavier than you??? If he was a big guy & set up the suspension for him, it could cause adverse suspension geometry if you are significantly lighter

Hey thanks once again for good ideas (and so quickly)...
- the front tyre is a new knobby at 14 psi
- Head bearings are good - bike has 1200 miles on it
- I'll set the rear sag as I don't know any info on previous owner
- I think I'll adjust the forks to 2 rings same as yours

ps.......I've been waiting for the boss (she who must be obeyed) to bring my external hard drive down to where I am so that I can e-mail some photos of my Sr311 Dato 2000 to you...she is coming down to Busselton this coming weekend....hence how come I've been riding the bike so much!!

Cheers and thanks
David

1) I'd think a new knobby @ 14psi might cause some squirley-ness (a real word???)

2) 1200 miles on the bearings may mean they are physically OK, but it doesn't mean the trees/bearings are set correctly. ie,... is there excessive slop in the head bearings due to the head nut being improprly torqued?

3) Good idea on setting the sag.

4) Is there a lowering link on the rear suspension? This may be why the forks are pushed up in the trees. If not, and the sag isn't correct for your body (too stiff, maybe) I could see raised forks affecting the geometry of the bike and making it very twitchy.

Those are my guesses. I don't own a Husky, so there is a chance the I don't know WTF I am talking about.

It might be the tire.


Some front knobbies do crazy things.


I'd take it off and get it spin-balanced. Do you see any wheel weights on it right now? Maybe it was never balanced from the start?

No problem another thing I was thinking is if the PO changed the suspension setting to make it turn quicker in tight trails

Check out the Husky forum in TT lots people who know these bikes inside out (racers & trail riders & everything in between) & if you do a search on suspensions & race sag, lots of advice on setting it up for yourself (weight\ riding style\ etc.) When you do the search, click on advanced, then husky forum, or you will get info on every bike made

* Drop your forks back to two lines.
* Balance the rims ... if you don't have access to a balancer add 3oz opposite the front rim lock and 3.5oz opposite the rear rim lock ... they'll be close.


Flexx bars, BRP submount with Scott's damper ...

Headshaker - Not now!!

Hey thanks for the help.

The front wheel was out of balance and slightly out of round!! I reseated tyre onto rim carefully ensuring that tyre concentric and then balanced it as suggested and now I have been unable to provoke headshake.

I have also made small adjustment to sag height as it wasn't sagging enough.

And to finish with I reset fork legs to two rings showing. (Headbearings perfect, no slop, no bind - as new)

I'm happier than ever - It really is a great bike.

Gave it an oil change and found the usual debris on screens and magnet....does this ever stop? Bike now has 2310k's (1450miles) on it. Also fitted a key switch to ignition to make me feel better!!

Cheers
David (and thanks once again to everyone for their help).
