    no tickover below 2k revs

    hi
    been a journey so far with this bike and haven't been out on it yet.
    now, I have a gen 1 with a aftermarket can and k+n filter.
    so, I damaged the tbs, and bought replacement from a running bike . not quite the same but hey ho (both gen1).

    I just cannot get it to tickover under 2k revs - if I lower it then it just dies.
    have checked for leaks on hoses - small and large.
    had a new fuel pump bout 6months ago.
    new plugs/coils/caps/leads aswell
    it used to tickover so I'm guessing a failure of something.

    so any guidance please, as I seem lost with it atm.
    This is my project which is nearing its end so no mot atm, so no chance of taking it anywhere to be looked at.
    thnx
    Hess

    ah ha
    seems me ol brain wasn't set when fitting the newer tbs.
    on seeing the handlebar throttle grip move when I put the choke on- I thought 'that's not right'.
    so, out came the Haynes and I set the choke cable which was waay out.
    I cant say that is the problem just yet as I'm awaiting new solenoid/battery wires( 170amp)to be delivered.
    now, does anyone think that this could of been the problem?

    I will post on this thread if ok -or not- lol

    hi hess,
    hope you are getting somewhere with your probs, im in the same place as you really got the bike in October and not ridden it yet ,but got a multitude of repairs and fixes done over winter.still need mot but too bloody cold yet.
    im just up the road from you at long Sutton,we will have to get our heads together perhaps when the weather improves and discuss all the challenges the rsv have thrown us
    if you need any reference we compare with photos etc one against the other,sometimes easier than a manual
    regards steve

    hi steve yeah sounds kool.

    now then, adjusted the cables -no joy
    checked coils/leads/caps spark plugs -all ok
    so,one cylinder had fuel on plugs
    checked fuel relay and cut off - both fried with one having no resistance at all.
    could this be the problem or just another one ! sigh!

    thnx caveman.
    above the ecu under the seat are 3 boxes.1 the diodes 2. the fuel relay and 3 cut off.

    hi all
    so, I borrowed a good multimeter and both are aroun5 which it should be.
    one less thing to sort now.
    but still just will not tickover , so now I suspect the fuel pressure regulator.
    These are expensive
    Is there anyway to check these as all I can find in the manual is try with a good one!

    well
    just following all the wires and down to the sidestand.
    disconnected the block only to see 2 wires soldered together, one leads down to the switch, which is also broken in half.
    seems I gotta search for new switch aswell.
    this could be the issue but cant tell till I replace this

    The sidestand switch is unreliable that why people get rid of it.
    (Only an American fuktard needs a sidetand switch)

    To be honest chap, your all over the place with this.

    If it idled fine with the old TB's but doesn't as soon as you bolt on new ones, that is a big clue. The Tb's didn't change the basic design across the whole years on Gen1 rsv's except on the limited edition models (Edwards etc). How do the new ones differ, have you actually measured the venturi to see if they match size etc to the originals ?

    A seller might easily mistake different aprilia model Tb's to be the same if they didn't look closely enough.

    -------------SOLVED_____________
    ok done everything but what I should of done in the first place was check all the connections were right.
    so when I got this ape as a project I removed nearly everything to clean.
    But I didn't look properly.
    On fitting all connections I missed the right way for one of them.
    After all this I connected the tip over upside down
    DOH!!
    well at least we know now what causes a problem lol
    All was forgotten when it struck up with a roar like thunder.
    not long now to complete this years task and get on the road

    hess
