Wobbles!

**apteryx_haasti** · 17th July 2006, 18:53

Hi there,

Quick total newbie question - my bike has developed a "shimmy" or "Wobble" or "shudder" (not sure how best to describe it) once I get over a certain speed. I first noticed on Friday and it is still there today. Starts at about 70 kph.

It seems quite similar to what happens in a car when the wheels aren't aligned.

Hence my newbie question - is that the problem? Or could it be something else? What can I check to see if it is alignment or something else. I have checked the tyre pressure and I think they are OK - but could tyre pressure cause this?

Thanks - I don't really like the wobble and I would like to make it go away, I presume it is probably not the best thing for my riding to have that going on!

Hope y'all can enlighten me,

Cheers.

strange you mean like when you need to get your wheels balanced on the cars

Hi there again, glad to hear you're still enjoying your riding.
I can't be of any help to you sorry, except to suggest to maybe ask someone down at Wellington Motorcycles about it or get them to take a look at it.
Keep on enjoying the pleasent weather at the mo aye!

Does it feel like its the back tyre? Or wobble in the rear? Although its not persistant

I've noticed the same with my Ginny at 70kph, thought it was just me.

My bikes going in for a full service and check tomorrow. I will ask the question and see whether it does it on way home.

aight... check that front wheel isnt bent, check that the front disk isnt bent, check you're steering head bearings to see if they are screwed, check that your rear axle is done up tight, check that you're chain is adjusted evenly (rear wheel is running straight and true) otherwise if all of that is sweet (you might need to take it to a shop for them to look at it) i suggest you get of the p, wacky backy, or whatever it is that is affecting your vision.

also check that you're tyres are at the correct pressure.

edit, hopefully someone in the welly area will be able to give you a hand, otherwise take it into the shop you got it from if it is a 2006 model it should still be under warranty.

Best thing to do is arrange a time for it get sorted and watch them so you can get an idea of how to fix it if you are mechanically minded/able.

my gf had the same problem the first few times she went on the motorway, I was following her in the cage and it was wobbiling everywhere!

However it doesn't wobble for me, Shes either holding the handle bars to tight or shes just not heavy enough.... i don't know

**sunhuntin** · 17th July 2006, 19:32

ive never noticed anything with mine. id get it checked out of its concerning you. best of luck getting it sorted!!!

I have the same problem on my volty when i get up around 270, nah just kidding but I do have the same problem and at the same speed, not sure whats doing it, maybe its god warning me to stay to the proper limit on my learners.

Oh, yep, that'll be what it is!

Like I would stay at 70 on the Wgtn motorway in traffic that's doing 80-100. Because at least if I was road paste, I'd be thin?

Not exactly the Atkins diet... (little drum roll)

But seriously folks - thanks for the advice. It's due for its 1000 km service in about 200 kms, so I will just ask then, unless it gets worse.

It is something I have just noticed, but it could have always been there and I have gotten past the "Oh crap, I'm gonna die on the motorway" and have only noticed now since I have more mind left over to pay attention to the bike?

Fub@r - it sounds similar to what you are describing. A wobble in the rear, not persistant, and not present at slower speeds (also goes away once you get over 85 ish - not that I'd know that...) If you remember to ask (and sorry for the late reply, I've been out since I wrote my post) I'd be interested to know what they say.

Cheers all.

Mines due for its 1000km service now, hence such an early service to make sure nothing has worked loose during the ruinning in maybe.

I will let you know what the servicing guy reckons

Not sure about the 85 k'ish as I'm stuck in auckland rush hour, I be lucky to get to 60

Cool, thanks Fub@r. Good luck with that Auckland traffic. For some reason Wgtn not too bad on the way to work, but coming home sucks. I am not brave enough to lane split (yet) so I just watch in envy all those other bikers going by.

I figure I'll grow into it...

It sounds most likely that it is simply a wheel out of balance. Being a newish bike I wouldn't expect the problem to be due to any worn out bearings or fork seals etc, rather something more simple.
If you have adjusted your chain recently it may be possible that you have over adjusted one of the chain tensioners on one side.
If you haven't touched the chain adjustment and but it seems like it is due to poor front to rear wheel alignment, make sure your axle is still done up tight - your rear wheel can't easily shift out of alignment unless the axle nut is loose, or you've crashed it and bent the frame and not told anybody!
PM me if you would like me to have a look, I work in Gracefield so I could pop out when I knock off. Either that or wait for the service. Whatever you decide, just make sure that your axle nut is done up nicely before you ride it next!
