    Possibilities that come to mind are:
    Blocked main jet.
    Broken needle from wear.
    Blocked filter.
    Other fuel tap/line restriction.
    Faulty fuel pump (would be worse at low tank level?)
    Float/needle issue.
    Carb vent filter blocked?

    I once had a bad electrical connection that acted like a blocked main jet. Would idle ok but die under throttle. Finally the wire broke off completely, killing other stuff and giving the game away.

    I try to get parts locally (WA) from Savage KTM, or from whichever online KTM store has my bits in stock.

    For parts, you’ll be hard pressed to beat Bolton’s KTM. They have probably the largest range in stock in Aus. And they are great with service in my experience.

    There’s a little nylon filter in the fuel inlet of the carb. Check that out too as it could possibly be the culprit.
    When you pull the fuel line off the carb you should see it in the metal pipe.
    It can be pulled out and cleaned (assuming someone else hasn’t thrown it away)

    +1 for Bolton’s as far as parts go.
    They carry a lot of stock and service is top notch.

    Check out the carb thread: https://advrider.com/index.php?threads/the-bst-40-bible.347184/

    It's really easy to pop the top off & check the slide & needle without pulling the carb so start there once you've checked the fuel supply. Check parts prices with motolab (US carb specialist & vendor on here) as well as locally.

    Cheers

    Thanks fellas for your input. I will try to illuminate the easy stuff first before pulling the carb off. Even throttle seems to have more play in it than usual if that meens anything. Hey kveldulv I would definitely interested in some of those parts. Cheers Steve

    All of it! Was gearing up to list in the flea market after the school holidays (as I'm about to be travelling interstate).
    But let me know if interested in anything.

    You should be able to use any two pronged automotive flasher unit if the KTM one is expensive!

    I bought 2 flasher units off fleabay with tune-able flashing speeds (for the LED's on the TTR250), just 'cos one was so cheap it seemed stupid not to get a spare, free postage and all.......

    ......fast forward to 2 weeks ago and Mr Blinky stopped working. A rough-as-guts trailride seems to have scrambled something inside (although there's no rattling...) so that spare came in real handy for both diagnosis and replacement. Both of them cost me about $2.60 all up, and a 10-day wait from China.

    At the price, I recommend buying a spare.

    On another subject, as far as I can tell the 640 uses the 6 raised heads of the steel disc bolts to activate the speedo pickup. Is this correct? (it isn't described anywhere in the manuals...)

    I have an aftermarket replacement disc that requires countersunk bolts that sit flush, so there is no corresponding raised bit of steel to trigger the sensor. I have thought of packing the sensor out from the brake caliper bracket to get it closer to the new flush steel bolts, and while it should work I feel it is a bit dodgy.

    I am open to suggestions on how to get the speedo to work. :dunno

    My

    My 2005 625 has just one magnet fixed to the rotor.. the sensor cable from the speedo is mounted on the brake caliper and reads each wheel rotation. InkedDSCN1560_LI.jpg



    I have fixed a magnet on to the rotor of my 701 with glue and silicon... instead of butchering the brake caliper.
    InkedDSCN1556_LI.jpg
    I use a road book for touring and the ICO trip meter and speed sensor cable from the road book, is mounted to the caliper with a home made bracket. The magnet I use on the 701 is the old one from the 625....very sticky magnet..it hasn't fallen off yet after 5000 kms.

    InkedDSCN1554_LI.jpg

    The 701 speedo shows 100 kmh....actual speed is 92 kmh
    The home made road book speedo reads 100...actual speed is 100kmh....and the ICO trip meter is accurate as well.

    Tom use some Araldite or similar two part metal stuff, geez forgotten what you call it. Someone will come up with it.
    Buy a rare earth magnet. Shit to a blanket and will work with a higher gap than your typical sensor magnet. Plenty and cheap on EBay if you have time to wait. Naturally glue it in line with your pickup.

    Dirt cheap on EBay. Can even get them to fit the connector

    I’ve got the same issue at the moment for my spare front wheel, bought a brake rotor for it that has countersunk holes. The Adv sensor uses the rotor bolt heads to trigger the sensor rather than the magnet setup that the other models use. I had a similar issue on a Honda a few years back, the solution was to get the counter sunk holes drilled out to a counterbore. Other option is an M6 lug bolt, if you can find one! My worry about packing the sensor out is that if it catches on something, it might get ripped off. Plus one more thing to change for me when I swap wheels.

    Get some countersunk washers machined to suit and then use the standard screws:hmmmmm
