    ...us the sordid details Loaded, demand is high for the holy relic and the desires of the faithful must be satiated.

    That and I need to have an excuse to avoid the tempting call of one of those wiz-bang US$100 adjustment tools that Creeper was so cruel as to show to the forlorn faithful.

    Can I have a refresher tutorial?

    Relocated to Toronto which I guess is aboot sea level
    Cleaned the airfilter that was looking like a muddy snowball
    Reinstalled the KTM racing sidecover with a piece of gutter guard because the original screen got sucked in the airbox (thats some intake velocity fer sure)
    Got Wings exhaust with the spark arrestor installed

    So its running real nice with the idle set at about 1600
    Front comes up in second with the right wack at the right time

    I turn the screw in and it sputters
    I turn the scew out and ever so slowly I get an increase in RPM
    Seemed like before I had a smaller sweet spot
    Maybe I just dont remember correctly but I thought the drill was open until idle raises then back off a bit

    Is that not the drill?

    First, thanks, for all the good advice over the years. You know whom you are . . .


    Next, allow
    me, to give back a little.
    I wanted a finger adjust carb idle circuit screw. I found out the Suzuki DR650SE used a BST40 . The nice folks at... http://www.kientech.com
    sell the part I was searching for.
    It's stainless steel, made "in town for us", fits and it's $15 bucks. (Not $35. sorry)
    I would also recommend:
    -The tool carrier- Made "in town" also! (can be made to fit the LC4s 6x70mm mounting points) claims to take weight of DR650
    -The Simple Stand-
    -The TM 40 pumper carb-
    Very nice people on the phone .

    In order to convince folks you need to do a bit of comparison first. Like creeper did:

    first to the stock screw:
    http://www.advrider.com/forums/showthread.php?t=69028
    and when that didn't work to a better replacement:
    http://www.advrider.com/forums/showthread.php?t=80366

    So you'll need to by a screw from the socialist first, then do some comparisons with the one you bought (pics and micrometer measurements are a plus).

    And finally I recommend you give us a comparison with the three - stock, Stenhouse's, and yours - installed. How do they work in the real-world? Dyno charts would be spliff of course.
