Steering wobble

[Plymadv]

Not sure if this is me tuning in on a non issue as I’ve got a big trip coming up or if it’s actually a real thing.

When accelerating hard and changing gear I seem to be getting some bar wobble. I’m used to the normal rear twitch from the final drive but bar wobble seems new. It could be me being a little harsh on the old girl or is it more likely to be something more serious that’s worn.

When I’ve noticed this I am giving it all it’s got.

You accelerate so weight transfers to rear/ front goes light, you back off to change gear, front weightens up, back tries to rise but shouldn't due to paralever. Power comes back on.

Is instability before power off or after power back on ?

Check easy things first, tyre pressures/condition, are all bolts at correct torque settings, then shocks, then telelever bearings.

Good luck.

I’d say it’s as I back off for the change I get a wobble. Could well be normal but I was getting a bit keen yesterday and have some big trip worries

I'd look at tyre profile/pressure in first instance, depending upon mileage etc, the shocks could also be due a rebuild.

Suspension. How old is it? I'd be looking at that.

Back off a bit, (a lot). It make your fuel go further, your tyres will last longer, you can go further for longer!.....On a big trip, you will thank me for this advice!

I rode down to Lake Como in one day, was there a day, then rode home again...max speed 80mph on the way home, because it made the fuel go so much further I actually made the trip in less time. You lose more fuelling than you gain by going faster. Left Bellagio at 10.00 Italian time, was home in my bed here in Uttoxeter, having had to wait for two ferries at Dover, by 03.00 that same night. Old Rs100 airhead, so not the comfiest of rides.

You will also live longer, or it just feels like it

You're on holiday, enjoy yourself.

Try changing the suspension settings and see if it changes anything, you might be surprised.

I’ve had another look at I can feel a slight clunk when the forks are at full extension. I’m going to change the fork oil and check the level. This could all be linked to the recent install of rebuilt GSA shocks.

As for taking it easy I normally do. This is just something I noticed when getting a little excited

Check the rear end - could be paralever bearings or the big one in the final drive. Grab the wheel at the 'quarter to three' and 'six o'clock' positions and see if you can feel any movement.

If the shocks have been rebuilt, perhaps take a moment to check the install is all set-up ok.

I'm just thinking if the rear is somehow softer than the front, it might make the front a little skittish under hard acceleration.

I'm no suspension expert, but i can confirm that with the set-up done about right, it can transform the bike.

Do you have panniers or a top box fitted ?

I will have a look as it’s certainly a bit twitchy at the moment.

No top box just gsa racks and no boxes when I noticed the issue.

What tyres do you have. TKC-70 while quick at low speed made the bike feel skittish at m-way speeds.
How old is the steering head bearing? Mine was changed at 50K because I had it apart. It was surprisingly knotchy.
Is the front ball joint worn or running dry?

Worn tkc 80’s that are due a swap next week. Head bearings are still good. I’m starting to think it’s fork related

Forks on a telever do very little in the great scheme of things, they just connect the wheels to the handle bars. The fork oil only lubricates the bushes in the sliders.
