    Okay, I give up.

    What's the trick for adjusting carbs on my XLT?

    No matter what I do, T handles or not, I can't reach even the high speed screws. Low speed screws are out of the question.

    on my 800 to get to the top i think the intake had to come off. To really get to the bottoms the carbs had to come off. I sold that and got a 1300r because I hated carbs that much. And I wanted a faster boat.

    I Was Told By A Dealer You Had To Remove The Pipe To Adjust The Carbs?

    I was told by a Yamaha dealer in 2002 when I first bought my ski new, that they had to remove the exhaust to adjust the carbs. Can it be done with the right tools, and tamper caps removed? Riva's ad on their stinger single pipe when it came out said how you can NOW adjust carbs with there new stinger......

    Hmm. This strikes an interesting twist to my tuning dilemma.
    So what now?
    How should I go about adjusting low speed? I"m at a loss.

    High speed I guess I could do by reading plugs or RPM. Either way it's still a booger of a job.

    For the top adjusters I use http://buy1.snapon.com/catalog/item....re&dir=catalog ,and you can buy different adapters for your application.
    On the bottom I use my fingers ,but I have a GPR .I have heard on the XLT the bottom adjusters are almost impossible to reach. I have a friend that had speedo cable brazed to his adjusters for extensions.

    What jets do you have in there? If you disabled the accellerator pump and have 110 lows with 1.5 N&S and 95 gram springs turn the adjuster out 1 turn and don't worry about it. Fercho developed this jetting and it is bullet proof. For the highs you can get the T handles and play fish with a flexible nut driver that is slotted. Again 120 or 125 main jets and turn it out 1 3/4 for 120's and 1 1/2 for 125's turns and forget it too. Leaninng it out for top performance will only get you in trouble if you forget to put them back and go riding in cold weather. I have never really noticed that many rpm's difference, maybe 40 max. Do you have a tach so you can make sure it maintains maximum rpm's?

    Hmm, I can bust it all loose and reset them again, shouldn't be too big of an issue.

    Fercho said that the 125 mains this close to sea level would slow down my rpm's, but not much.

    My biggest problem is that the engine is loading up at idle BIG time..
    Top end really doesn't run bad, just way down on RPM's.
    I don't have a tach - YET. It's on the books.

    dreamometer before rebuild - 68-ish
    dreamometer after rebuild - 58-ish.

    I just wanted to confirm what Spud said on the lows. I set them @ one out way back in March and havent touched them since.

    I havent even thought about them because it never loads up off idle. One turn out should be perfect.

    125 mains are for close to sea level with no choke plates. If you live at a higher elevation and had choke plates in 120's would be the ticket.

    What are your pilot jets and needle and seats?
    What springs are you using?
    What is your popoff?
    How many turns out are your low speed adjusters?
