Just rode the bike home from work, and at lower constant speeds I can only describe the bike as sounding like it was mildly shivering.
Open the throttle up and it responded absolutely fine, but to me something is not quite right, but I don't know what?
I balanced the carbs not so long ago and they were all good.
The only similar thing I've had before was when my TPS was gradually breaking down, but I just checked that and it pinged straight to 5K rpm so I'm a bit stumped, I don't even know where to begin?
Any ideas anyone?

put a nice warm jumper on it , sorry, I'm not helping am I :o
Old enough to know better
when you say shivvering....
Dull vibration of a definite small stutter???
Does it seem like a timing issue of a starvation issue, i.e. does it seem very ropey and un-responsive, appears no....or does it seem starved of something...i would geuss it is sturrling for air or fuel....for some reason....
anything been taken off and cleaned recently...
i thought i had killed my engine today, but turned out i forgot to put an ignition coil back on - the relief! :lol
Not touched anything BUT the last 2 tanks had some STP Fuel System Cleaner in them, and I'm wondering if it's unsettled something then duly clogged something else up?
Imagine the sound of someone's mouth/jaw when they're really cold and shivering, it's a spot on description.
May just need a good blast, but I know my bike well by sound and right now it's just not right to me.

Air filter due a clean or replacement ?

K&N, the bike is only on around 45K in total, not entirely sure without checking when fitted but it shouldn't be that anyway.

Still reminds me of when the TPS goes wrong, i've always known when it was about to go, but as i said it's not showing any physical signs yet so it's all a bit puzzling, although i still won't rule it out.

Why shouldn't it be that? Have you ever cleaned the filter since you fitted it? Always worth a check, also make sure your plug caps are tight on the leads. This would be just a start point.
What many do not realise is the the Sahara dust issues last year left many air filters requiring premature changing/cleaning.
I cleaned 2 K&N filters for 2 bikes used in the UK around that time and both had over 5mm of dust on the base of the filter box which was oil laden and going nowhere. The amount which came out of the filter was like they had ridden through a sand storm.

Okey doke, fair point, i'll have to take a look at that on Saturday. :thumbup
Bit more info for the record, did the same again this morning, most noticeably between 2000-3000rpm, but especially noticeable at 2500rpm.
Found a clear bit of road and gave it some welly, and it responded with no issues at all or spluttering, I went up to about 80mph in a few seconds without faltering, restricted feeling or any bad noises.
Yet when I ride around the 2500rpm mark it sounds more like a twin engine with quicker pulsing noises?

Just a thought with the fuel cleaner in mind - at what revs does the 600 change over from pilot jets to main jets in the cars? Blocked idle jets ???
Those are my principles...if you don't like them I have others.
Ahhhh Story of my life Darrsi,i have exactly the same prolems for months now,and i cant find a solution,neither any mechanic can...
Hope you will be lucky...

Forgot to mention, the idle is solid @ 1200rpm, no hunting at all.

What were the tolerances at the time, or were you told?

No mate, it was when I got the bike, had a load of things done.
