    My electrical diag manual hasnt arived yet,  but l cant wait , still sniffin about the bike ,  gotta find the problem eventually,

    dont  l ?

    from memory the iac moves out  / in ( if you look up at  it ,,viewing  the inside the inlet manifold) upon turning the ignition on?

    or is it  turning it off ?

    mine moves  out  then  in  once, , when  l turn the ignition  off,  Does this sound   correct ???

    Thanks scotty, yes it sounds like its working o.k.
    let me run this question by you,? for your opinion...

    if l re-install all the origonal parts, aircleaner & fittings, the origonal exhaust , and origonal ecm, so the bike is as was when it came from the shop "new," should it start and settle into an idle?

    Or would have running a T/Max for the past 7 months had a (corrupt) effect on re-installing & running the abve mentioned parts?

    l have fitted up the origonals , motor is running fast,

    Scotty,, the bike has never had a spanner to it, the only person to have touched it was the guy who base maped the t/max after l installed it,

    l did the intake leak test (can of moisture dispersant) didnt make any differance to the fast running,
    since the bike was on the lift and the tank was loose fitted, removed the tank to get to the aircleaner, INJECTORS,IAT, IAC, MAP, removed checked o rings, cleaned,new air/cl. gasket, looked for wear, The only thing l found was that the IAC module ( Assembled in Mexico)has a slight wear ring around the tappered end that moves out /in , but it looks like normal wear, so lve put it back into service, Rode around the block, motor was running faster than before when l got back to the drivway out front, , turned it off put it back up on the lift,started up,, ran a little slower,, as before the ride,, (3 Days back) l removed cleaned, checked, CKP, ET, regulator, & their conections,

    o.k. backed off the cables , id re-set them again this morning, but doesnt hurt to double check, its got me buggered!
    im thinking about the IAC & the scratch around it, it must have contacted something, come out a bit far maybe? l wouldn't have thought it would change the running of the bike,(the scratch) but l cant think of anything else?, except maybe inside the tank,
    if l run the bike with the aircleaner off put a finger over the iac hole, (partially over the hole) dependant on how much you cover the hole ! it slows the motor,, thats just an observation , its about $100 (iac ) to take that guess..

    Scotty...l dried the manifold first as there was a bit of fuel at the rear,

    full throttle with throttle stop to hold it there in position,

    turned on for 15 seconds, then off

    6 times , watching with pen light , No, manifold is dry....

    Scotty , its got me, ive had every pluged in wire, sensor, apart, battery cables, earth, fuse box, fuel pump, fuel pump filter/sock.
    senders,filters, gaskets,
    ive run out of things to look for, l thought the diag manual might help,(when it arrives)
    Since its running fast, & a wisp of black smoke, there is an issue somewhere??
    its given me nightmares...

    stix68.. Ecm is std. was removed with 5,000km. & is as new,  replaced with T/Max.

    ive put the std stuff back on the bike to check out the problem with running..(in case it was tmax issue)

    l wont purchase a IAC just yet as this one shows that its operating correctly,

    when the diag manual arrives ill go throygh the trouble shoot with my symtems (& find my dictionary)

    if the bike is still playing up then !!! & l havnt been able to find out whot it is!!!

    Go to plan "B"

    plan "B" ......Re-install T/Max , stage 1 air./cl,,& straight shots, 

    take 1 computer from house ,set up in shed, purchase 15mt of telephone cable , run from house to shed

    make sure the dog doesnt chew the cable up this time, lock him up,

    ill run the bike , looking at the AFR readings.. cause l think its a air/fuel problem

    im not really sure about computer based bikes,  if l find somethiong "funny"

    should l change the reading? or would that just be masking what could be the issue on the bike??

    ill probably change the reading,, & when l get in to trouble & f**k things up

    ill ask on the forum.. always a wealth of help,

    Wot else can l do???????

    its there !!!!somewhere!!!

    Hey Ho Wozza.. l heard you were looking for a real good EFI system, cause youv'e had enough of that old carb your running, l know were you can get a realy goopd set up , change over for your old antiquated set up your running, complete hardly used!! wont cost you much about a G....

    l shall clean em up as they are sooty,for the closed loop test, l think l can run open loop as well..just (unclick)the box.

    so's l can check that the 02's arnt in the way....something like that....

    Stix68..its idleing high & a wisp of black smoke with the stock ecm,(no 02 sensors on stock ecm) rides well at all rpm no missing, jerking, plugs are a nice colour,a pleasure to ride except for the idle n wisp of black..

    t/max fitted closed loop,(02 sensors) idles at setting l think its 960rpm from memory, missing ,billowing black smoke from idle up to mid range, (probably the 02's trying to get air/fuel right but cant,

    is ridable at 100/110kmh & up , plugs are fouled up as are the 02 sensors..(sooty black) used 1/2 tank of fuel at 80kph over about 60km.distance,
    used less fuel when l sat on 110kph for the rest of the trip home,

    canister inlet capped, thrtle stop o.k. TPS ive never touched, l could take it off and have a look but ill wait for the book to lob,
    Is that something that could go out of wack by itself? & cause rough rich running?

    if the symtoms l mentioned sound like swaping injectors to see if it helps, id take you up on that offer , before l re-fit the t/max be a good idea. only take me about 15 minutes to fit
    since im getting quicker at disasembling the bike tank and fittings now,

    l can assure you l will take good care of them, if you wanted to send them Aust. post. C.O.D , l will have them back in the post(post paid) the following day after fitting and trying,,

    if you decide to send them sing out, ill pm my postal details to you....thanks in advance...

    sophtayl, 2006 dyna strretbob(aust.model) didnt have 02.s fitted, had the bungs in the header pipes to take them, capped off with a bolt,

    an electrical spike could possably have happened , a few days before the problem appeared, but there were no fuses blown or any thing to suggest it, the bike did get wet, real wet,! ! but after it was dried out, ran like a malley bull for days until this..

    but ive also swaped back to origonal ecm & other std, parts that were on the bike from new,

    so if the spike you mention affects the(unit) ecm,? then it wont be it ..

    l will check  range of readings, its got to be done, surely !!  somethings got to turn up there!!

    Scotty, l pulled the plug on the engine temp sensor, started her up, shit loads of black sooty smoke, it didnt like it at all,
    so since it runs a whole lot better pluged in , im thinking leave that for now, & keep looking...
    Can the ETS go out slowly? or would it just give up at once?...

    Scotty, throttle blade (shaft with butterfly?) all good, no appreciable play or damage,

    Hilly13, after pulling the plug on the temp sender yesterday , thought it might not give a good reading , even if it was faulty its probably better to have it pluged in so's ecm can read it,& not just have the wires just hanging there,

    So l got my hands on a new sender, ,they all must be the same?,  part number 32446-99  but.. on the brass unit it self it has the number 3257.. on my existing brass unit it has 0536. l dont know wot that stands for..

    l hooked it up anyway , it has made no differance to the running of bike, l guess l can count the sender out as the culprit..

    Scotty, l did chase the wiring from the temp sender to the ecm & fuse box, all good ,unwrapped  the tar type tape

    at the "Y"  join , everything looks as new, no sign of problems in any of the wiring through out the whole bike...

    yes it does, l was just now looking at the map, & all the other modules on the injector body, could go out and buy all of them , rplace the lot!! but thats not the answer, my diag book will be here monday/tuesday , if l check the readings on the sensors it should show the problem if it is in EFI area?

    l cant do any more now till thats done, im chasing my tail , going over , over, & over again the stuff ive already looked at,

    stix68 is sending a set of injectors to try, so that will count/discount that area....

    Scotty, l pm'd stix, my bike details & type injectors, if his are suitable hes going to send them across,
    good stuff!!.. (for blockages) they tell me they are vibrated as the holes are very fine and shouldnt stick anything in them or blow them out. " Vibrated "?? Why Not ! ! l got my orbital sander inverted with a 8mm piece of foam attetched , sos not to damage the units body, give em a good bbbrrr for 5 mines ..didnt change things... worth a shot,,

    stix 68,, thanks for the offer on those injectors anyways mate,,

    PKM... No error codes showing,

    only errors show when l run the bike with something unpluged, ...sure you'd think an error code would show up if there was  an issuie with the EFI. or other faulty componant  else where on the bike..

    But all l can tell you is there is a fault some where.. and l havn't  find it yet.....

     thanks to the HDF members who have given  their invaluable .advise, l know its near imposable to diagnose over the net, but its all been a big help,.. what better way to know your bike than to pull it apart..get ya head into all those places you dont normally...its my first electronic bike, so this has put me off a bit, the older less advanced carbed,points,etc. bikes have got a lot going for them, l dont care wot anybody sais......However l wont be going back now,, keep moving forward!!!

    Diag, book arrived, makes for a good read,... to check the fuel pressure, EFI , wiring, ecm, etc, need quit a few tools ,

    can do some checks on the wiring with a multi meter, but not much else,

    l had the IAC out again today, just to tripple check on it & the other modules on the inlet, put it all back together, it actualy ran a bit slower for about 3 seconds on start up, l let it run while l went out side to do wee's, just to see if it would come down ,
    about wot? 2 -3 minutes,.... header pipes were glowing red....
