    i keep on seeing videos of the husqvarnas and people seam to start them real easy, seen few of the te 610 and thats a bit harder, do you think its because they have dellertos on? maybe i should get a FCR carb for the husky and it will sort the starting issues

    Greets all...thanks for all the great info and taking the time to share it.
    I've just this week bought a '98 TE410 (in Adelaide South Australia) and spent today riding...when I could get it started. Easy cold but when warm it is a right PIG to start if at all...keen to try the method suggested in this thread as it makes sense. Fingers crossed or she may get traded/sold...don't need the grief.

    When the 410 is running though is it a great ride..really good with loads of power and good braking...I've ridden the KTM400's on a Cambodian bike tour earlier this year and the Husky has a few similarities...minus electric start...THAT is a mod I would gladly do. :)
    Cheers all.

    No need for an electric start - just check your carb set up is correct and use the right spark plug...

    Mainjet 175
    Pilot 62
    Start 60

    NGK C7E (mine did not start okay with a c8e- its was a pain to get it to run, but once the engine was running its been okay)

    Hi,

    my bike is a bone stock 93 TE610 (maybe ist called WXE in your Country)

    Starting is a lot better with the bigger pilot and starting jet.

    Hi Guys,

    There is a lot of great information here for new single cam owners.

    Cheers, Dave.

    While on this topic I was wondering if any other te570 owners have a jetting chart. I have the exhaust restrictive removed(I'm pretty sure). And the holes in the air box. I can find stock jetting data, but I need to know what numbers I need for riding above 6500ft. Cheers!

    The only jetting I could find came from an Australian Importer, probably sea level.

    At least you have a start, you will need to do plug chops.


    TE570

    -------------Stock------------------------------- Modified (modified air box and muffler)

    Main jet, ---175 ----------------------------------------------170

    Pilot,-------- 62 ------------------------------------------------62

    needle,---- 3rd from top ------------------------------------2nd from top


    Cheers, Dave.

    Thank you sir. I'll keep plodding along, searching, searching.

    I did find some info on the jets and how you compensate for elevation.

    For example(probably wrong): for every 1000ft elevation gain you lean your main jet two numbers.

    Make sense? I've just gotta find where I wrote that down and look at these numbers and start a mathin some numbers

    That would make sense, higher the elevation, the less air, so leaner on the main jet.

    I'm no expert, but I will do some research.

    Cheers, Dave.

    After reading through this thread I am also interested in jet settings for riding at different elevations. I'm going to ride at ~4000ft. in a few weeks and I would like to do have my jetting done beforehand. I ordered 3 sizes down and 1 size up for both the pilot and main, but I don't exactly want to use the trial and error method to do my setup...

    Just as another data point, my current jetting is at sea level is:

    Mods: Airbox mod, supertrapp exhaust
    Main - 170
    Pilot - 62
    Start - 60
    Needle - 2nd from top
    Air screw - 1/2 turn out

    The 62 pilot is a little rich since I get a small puff of smoke when I roll on the throttle from idle. Going to swap with a size 60 pilot pretty soon to see if that helps.

    Braap, try bumping that needle down one, so 1 from top

    I am at sea level:

    01 570TE

    Stock slow jet

    170 main

    I am going to try to move from the k32 needle to the k30. It's a dual taper and should be just a hair richer than the 32... Anyone tried this yet?

    Also did any 610/570 bikes come with dellorto pumpers? I know the fcr and mikuni s are generally equipped.
