i've noticed my bike feels a bit wishy washey at the rear wheel when I pile on the power while leaning a little, for instance when flicking over to the left to exit a roundabout. My rear suspension is adjustable and I'm wondering if tightening up a bit is the thing to do?

Checked pressures?
Checked wheel bearings?
Checked swing arm bearings?
Checked chain tension?
Checked headstock bearings?

Is a new bike so bearings are all sound and the chain is at good tension and tire pressures are also fine.

Has it always done it?

If not, and it's a recent thing then something has changed, so it's unlikely to be your suspension settings unless you/someone has been messing

Also what do you mean by wishy washy?

Does it slip or slide?
Under power or on the brakes?
Does the bike under or oversteer?

Its only recently i've been experimenting with pileing on the power and its most noticable on one particular roundabout. i've not adjusted anything yet thinking i'd better ask advice here first.

On an XJ6 the only thing you should do is set the sag. There's loads of guides out there for how to do that. This is vitally important to good handling. As mentioned earlier, check everything else first.

By wishy wasey im trying convey that the rear end feels a bit soft and squirms a little as the torque increases. As the bike is in tip top condition and ive never adjusted the suspension im just wondering if this is the kind of thing a suspension tweak fixes.

As for sag, im 15 stone, is likely at my weight a bike would need some adjustment?

I think therein lies your answer......

Either road surface or camber of the exit.

The roundabout is on a hill and has camber as well as a poor surface but ive noticed the slight wallowing when powering out of other corners as well.

I looked up a suspension setup thread and found a guide here https://www.gostar-racing.com/information/motorcycle_suspension_set-up.htm

So im going to check sag at the weekend.

Set the sag first. Don't touch anything else till the sag is correct.

What this will do is put the shock inside it's optimum working range of it's stroke, the rest of the adjustments are useless till this is correct.

If you're a chunky monkey then yes. Not enough preload at the rear will make it feel soft, wallowy under power and there won't be enough weight on the front causing the steering to lack precision.

Come back to us if your suspenders are adjustable for compression and rebound, but I doubt they will be.

I can only adjust for rear preload. It will be interesting to see how much sag the bikes at the moment. I will do a quick masurement tomorrow.

Try it! I found the same with mine, felt a bit unsettled exiting roundabouts when applying power. I Turned the adjuster 2 clicks I think to stiffen it up and it made it feel much more planted.

I weigh 12.5-13st and found that increasing the rear preload on my Hornet really improved the feel of the bike when cornering.

Add one click at a time and just go for a ride to feel for any improvement.
I went 2 in the end. (Set 4/7 instead of the factory 2/7).

Feels like a new bike. Just more 'on it' ?! Hard to describe but instantly noticeable.

Note down where it is now, go one click at a time, you can always click back.

I'm going to do that but after i've taken measurements of current sag to see how reality checks against the theory.

I would suggest measuring first before you break out the ass-dyno.

You need a mate, a piece of batten and a tape measure. Use the rear axle and a point on the rear fairing as a datum and measure the sag. Adjust it as per the user manual and/or the setup guide above. Then see how it feels and work from there.

FYI I'm 13.5 stone and set my Hornet to 4 or 5 clicks.
