i was keeping up, until i miss-shifted on 5th, and bounced off the rev limiter   

Still was good ride out, great scenery! A nice warm up for tomorrows run to Wales & Isle of Man!

Yeah, it was a good run out - notice you had a dark visor, must have been getting a bit black at the end when the sun went down

I think that time was the only time I had it wide open from a standing start.  Need to find someone who can properly service it - I can't balance 4 carbs. It used an excessive amount of fuel to do those 100m, used a whole tank. It was a bit poppy/missy until we stopped at Bibury - seemed a bit better after that.

what year and model? how many miles? is it stock? is it the gay 125bhp restricted version or the proper full fat manly unrestricted job with proper carb tops?

balancing the carbs only affects tick over.

Full fat, fully gay, fully restricted, bog standard UK spec with the flat carb tops. 125bhp when it left the factory in 1989. Occasionally look on egay for new carb tops, not sure if it needs new jets?

[TheBoy]

Its the full beans version, can you imagine TB with gay version? Not many miles 40k something i think? its also stock... for its age it does look quite nice, it does have an appalling turning lock though 

3 out of 4 ain't bad - it is the UK spec, restricted version.  Yes, I know it still shows your bulky tank a clean set of heels

Carbs out of balance mostly affect idle and light load running - and can cause it to pop and splutter a bit on the overrun. 8-)

If it's running rich and thirsty I think it might need a little more attention to the carbs. Maybe the mixture needs adjustment or the floats are a bit sticky?

Not familiar with the setup on those but I'll bring my synchrometer to the Lakes if you would like to borrow it?

What you really need to do, though, is bin those carbs and Megasquirt it but I am not about to volunteer to ride pillion with a laptop to tune it.

Carbs always were a PITA, never liked them.

How can I tell if mixture is out?

How can I tell if mixture is out?

Fit a Lambda sensor.

The problem is, each cylinder has its' own choke so one could be rich and the next lean.

Setting up carbs also normally relies on them being set up at idle and automatically being correct over the full range of speeds and loads thereafter. A reasonable assumption when they are new but once the needles have started to wear, jets have blocked with crud, etc. it all goes wrong.

Don't forget the timing is probably adjustable too?

What condition are the plugs in?

Can you safely cut the engine straight after a full-bore acceleration through the gears, coast to a halt and check the plugs? Might tell you something about the mixture under full load and also indicate of there's a pot that's running richer than the others. Put a dose of lead substitute like millers VSP through it when you do this to give the plugs some colour.

Other than that, find out the proper procedure for tuning the carbs and see if that improves it before doing too much else.

Or spend some money and send it to a reputable bike tuner.    :-/

Plugs replaced last year, along with (oiled) air filter.  Not a quick job to get to plugs, as tank has to come off.

Got the Haynes BoB and the Kawasaki manuals, will have a gander - but its bloody carbs, I hate them

[CaptainZok]

3 gallons.
Bloody hell Jaime that's enough to reduce a whole caravan site to ashes.

have the valve clearances been done at any point?

Oh, the joys of shimming valves. Should have hydraulic tappets instead. They never.. er.. ratt... I'll get my coat.

So, gay then! hmm?    (snigger)

Not in my ownership.  In fact, other than consumables, nothing has been done...

Completely and utterly.  Not quite as gay as a BMW GS1200, as it has no trouble leaving that in its mirrors.

Keep looking on the 'gay for new carb tops, never come up at sensible money

Went out for a blast on my 900 too, went to Stow-on-the Wold..........(not far from me).I was the loony on the Suzuki RF900 all in black with a black helmet and black visor, wish I had known you were about there.....perhaps we'll meet up sometime soon?

That's the one with a Darth Vader rear light ......if memory serves. ...a very underated bike....

Please take care on two wheels lads yesterday was the first anniversary of my sons best freind getting killed outright at the age of twenty by a car pulling out of a side road on him, my boy was at his side when the paramedics pronounced him dead. Remember you could be the best bike rider in the world but you are so vunerable on a bike in the event of a crash
