So went out today to start up the bike to keep the battery charged and noticed my bike goes from idle 1200 rpm straight to 2800rpm . I can hold it at any rpm after 2800 rpm just not in between 1200 and 2800 . The choke also only takes it straight up to 2800 no adjustment of the lever will let it sit in between either . Strange one as if I back off the idle screw it will drop right down and stop running .
Any ideas folks ?

It might be a sticky choke cable, or the slide that operates the chokes. If they aren't moving smoothly they would jump from one setting to another.

Both using the throttle and - or choke misses out this range

Im not sure about this one Mick but are all the vacumn pipes on correctly....are all the plugs in good nick....any air leakages at the carb intakes (this can be checked with wd40...spray a little in while running ...if air is leaking in the bike will rev up a little).....

Will have a look and make sure the rubbers are all sealed up cheers , not knowing whats on the hidden side of the tps is it something I want to remove and clean up ?

So finally got 2 mins to test out the procedure above
First of all this is a very simple job to do even for the none mechanically minded.
On the left hand end of the bank of carbs you will see a black cylindrical object with a connector coming out of it. With the ignition switched OFF disconnect the connector.Â
Then switch the ignition ONÂ (do not start the bike)Â and you will see the rev counter shoot round to 10,00rpm then back to zero this is normal. It`s just telling you that the TPS isn`t connected.
While the ignition is switched ON reconnect the TPS connector you are now in the TPS diagnostic mode and the reading on the rev counter should be 5,000 to 5,500
with ignition off I unpluged the tps but my rev counter sweeps to just over 3000 then back to 0. With the ignition on it sweeps to 5500 ........ anybody know what that means ?

I think it means the TPS needs to be adjusted.....if you look in your manual section 4.6 it explains what to do....doesn't look to difficult

Its confusing though as when is diagnostic mode (tps connected)the reading is correct , its when its disconnected it only sweeps to 3k not 10k

Not yet bud trying to find out what sweeping to 3k not 10k with tps disconnected means first before I go moving the tps

Went out and had a wee fiddle and it is set correct its at approx 5400 if I turn on way it goes up to max and if I turn the other it goes to 0 though I will say I cant fine adjust to bang on 5k as per haynes

Dont want to anoy neighbours but I can now get it to sit at 2k if rev it up and I very finely back off the throttle. from 2.5k to just over 3k it will sit where I want then it jumps from just over 3k to 4k where it will sit no problem .... dont wana test higher the now as neighbours will complain. So bleeding annoying as its all nearly there lol

if the throttle cable is trapped it could have a similar effect. Take the petrol tank off and see if the problem goes away.

So got tank off no change, moved throttle cables about and no change, air filter out and other than running poop no change And by no change I mean still missing out rpms

Its almost as if the throttle is massively to sensitive. Excuse my ignorance but how would a failing tps sensor effect the throttle response as it was my under standing that it had nowt to do with the amount of fuel and air the carbs provided but slightly adjusted the timing

Have you tried balancing the carbs?
If they're out of sync the throttle response could be affected.

Not yet mate as dont have the stuff to do it. Its realy strange that a few turns of the idle adjuster and it will sit at 2k all day but almost impossible to get it to sit steady at 2k using the throttle

I thought it was an ignition problem, dodgy coil perhaps, one of the codes is definitely ignition!

From what I have read online
With tps unplugged it reads 3k which I read as fault at tps which would stand to reason as its unplugged.
Then plugging it in it reads just over 5k if I adjust tps either way it drops to 0k or 11000k so then I moved it back in centre it settles on just over 5k so I think that means its set correct.
Do you have a list of fault codes hrhpenfold ? Its not like its struggling then fires into life its quite the opposite its far to eager to rev ha ha just a tiny touch of the throttle and it flies past where you want it to be.
My plan of attack for now is pull the air filter and wash then re-oil then whip carbs off, give them a clean again, put on a new (newer) tps then make sure all joins on the air intake is sealed up good and new tps is at correct angle.
Then cross everything and hope for the best
Failing that I will need to save up for new coils and plugs but that might take a while as im skint just now ha ha
kinda wondering if its been rejetted at some point as its running a nexxus system and k&n filter and alan said it felt quicker than his when he rode it home

No I don't have the codes, my D6 is old school, without TPS,
First thing I would do is give it a service, including new plugs, new fuel filter and air filter,
I would set the re oil able filter aside to see if a standard one improved the running, as you can get the re usable one to contain to much oil!!

Yeah will Order up the consumables once ive been paid this month, kicker is I have new plugs I bought tail end of last year but turns out they sent the wrong ones and ive left it to late to send them back. They must be for older xj600 as they are to wide think theh are dr8 or something and I need cr8

Do you have a list of fault codes hrhpenfold ? You can read codes on this bike! How do you do that, where do you plug the code reader in and what sort of code reader do you use?

Code 1 - bike won't start Code 2 - push/pull/click all wires/switches Code 3 - try to jump start bike Code 4 - 2@ *things* with a ferkin great hammer Code 5 - conclude bike is fecked, push it back in garage and have a beer Code 6 - sell it to Martin Hth,

Aye it will be something small and stupid thats my thinking of taking it all off again and put it back on making sure everything is sealed up correct and see how it goes

Right so had to take some time off work today so had a hour the day . Got air box off cleaned air filter ran a remote fuel tank with some new fuel, randomly spraying carb cleaner in the fuel line and spraying in every orifice of the carbs till the tin was used.
Interesting result full choke now gives me 5k instead of just 3k.... maybe the choke is sticking some where so when I touch throttle it kind of switches choke on a bit .
I dont have a clue how the two are linked but the little poles slide in and out the carb housings freely
