SV650S hates the cold weather :(

  1. Hi,

    I really need help with this, my bike runs great when the weather's
    warm, as soon as it gets cold, its a different story. The bike stutters
    and stalls while downshifting, upshifting, the revs dies for a second or
    two before picking up again with a jerk.

    This happened today went for a ride along the GOR ( or tried to ), the
    bike ran great uptill Torquay, then it got cloudy, the weather started
    getting a little nippy and the problem started........ I stalled twice
    before i gave up and headed back to Melbourne, didn't wanna have her
    stall on me in a corner and end up crashing! I've heard the carbed SVs
    have problems with carb icing, the bike runs better after i put a water
    treatment thingy into the tank, but thats a pain in the butt!

    I heard Suzuki offered carby heaters as an option in Oz and the UK, how
    would i go about getting one of these from them, will i have to pay for
    it (hope not)?

    If this doesn't work, i'll end up selling the bike, its takes all the
    fun outta the ride, totally ruined my fukkin day. :(

    Please help fellas

    carb icing occurs with constant throttle at constant speed
    is this what is happening to you ??

    it is more likely that your bike is running a little lean
    and when the temp drops the air is more dense (more oxygen)
    so you have these probs

    a minor adjustment of the mixture could be all that is required

  3. Yep i checked up all the symptoms of carb icing on the web and my bike
    has each and every one of them. As soon as it got hot again today, when
    i was on my way back home, she started running great!

    I'll try messing with the mixture, but i've had the mechanics look at it
    before, it keeps happening :(

    and which mechanics would this be ???

    did you tell them exactly what the problems are you are having ??
    did they question you at all as to where /when it happens ??

    or was this the dealer with the 2nd year grease monkey ??

    what did they actually do ??

    How did it run in July when the weather was warm?

  6. Crappy, but now its getting worse, used to be a only on <10c days, now
    its happening when its a little warmer!
    Rohit Budhwar, Dec 5, 2004
  7. Mechanics would be :-
    1) Peter Stevens in dandenong where i bought the bike from.
    2) Ron at Balls in sunshine.
    Started happening after i had the bike piped and rejetted, cranking up
    the idle helped a little,but not much. I spent a heap of time on the SV
    forums figuring it out, then it turns out, a whole heap of people have
    had this problem on carbed Svs.

    hmm so bike was ok before you had the pipe and rejet ??

    doesnt that tell you something ??????

    as i said before you have a prob with mixture

    want it right then get it on a dyno and get a mixture chart

  9. the problem is it only happens in the cold, so its kinda hard to
    replicate, always been kinda sunny when i go to the workshop. I told 'em
    everything.....usually when its in for a service, i get the bike back,
    i t runs great then at night when it gets colder, things start going
    funny, revs drop when i try to shift after i've been travelling at a
    constant speed eg. freeway, i sputters a bit then kicks in with a nasty
    jerk or just stalls.

  10. Haha, thought you'd get a laugh outta that ;)
    ok will do, who do you recommend for it? Should i dig into it myself,
    i'm no mech whiz at bikes, thats the only thing that scares me, i might
    **** it up even further.

    based on your other post it does sound like carb icing but
    as you said , it was ok before the pipe and jetting went on

    get it on a dyno that can do mixture graph and tell them what probs you are

    i'm in syd so dont know anyone

    anyone bueller ? bueller ?

    Dynobike in Moorabbin is a name that regularly crops up. I haven't dealt with them myself but a few
    people I know have and highly reccommend them.

  14. the problem is it only happens in the cold, so its kinda hard to
    So leave it with them overnight and ask them to get someone to ride
    the bike home at night to see the problem..

    when it gets cold and it starts going funny put the chock on and see if it
    then starts to work ok.
    if it does then it is most likely to be mixure.

    There's your problem right there (I'm a thousand miles
    away, and even *I* know that!!!)

    There's the other problem right there. Too much rice.

    G, no rice.

    I'd definitely also consider water contamination and spark plug shorting as issues to check on SV's.

    Both issues well-documented elsewhere on SV sites but briefly:-

    1) if drainage hole from filler tank blocked, water gets in tank when unlocked to put fuel in.

    fix: check for any kinks in drainage hose, can be crimped if putting tank on.

    drain tank/carby bowls and run cup of meths every tank for a few tanks to get rid of water.

    2) front spark plug recess can fill with water (washing or wet days) and plug cap shorts.

    3) a general good state of tune is point fixing issues that mask a poor state of tune.

    4) Live in a region with recognised reliable summer climate :)

    That's one. How many more "plugs" do you have to give them?
