    i just changed reeds in my 05 600xc from vforce2 to vforce3 and am having a hesatation on initial takeoff.  i was wondering if ypu have any ideas on weather its maybe too rich or lean. the reeds are the only change i have made  id appreciate any help.

    I'm not much of a believer of v-force reeds on these stock 600 sleds. Its a lot of money spent for a small improvement in throttle response. That all said and done, you will need to adjust the fuel screws and maybe the air screws slightly to compensate for the new cages. When I installed a set of Boyesen power reed petals in my 05 XC 600 I needed to richen the fuel screws a little less than 1/4 turn out to get back where I was. My guess you will need to do the same. You can first try blipping the choke before nailing it wot if it corrects the problem before making any changes, this will indicate if its lean.

    Hmmm, sounds like you've got an Air Leak somewhere. Did you follow those Instructions like using the template to make sure everything lines up perfectly. The Slightest little change in Mixture Flow for an Obsrtuction can cause a whole Whack of Problems including making her run lean. Does it quit this nonsense after you go further? How are your Sparkplugs? If she's lean enough to make her hesitate, your Plugs won't look good either. Sometimes it can be as simple as a Split Airbox allowing extra (too much) into the Carbs.

    Maybe Gramps or Jasper or someone else can help you out more 4 sure.

    Good Luck,

    at first i turned the fuel screws out a quarter turn still the same after reading jaspers response i then turned the air screws in 1-8th turn and it straightened out. now its a little rich has like a gargle at 30 mph but runs very strong when pinned to the bar from start to finish. gonna turn fuel screw in 1-8th more.

    No two sleds tune exactly the same, even on the same day. Seems like you got it under control by making small adjustments. You get basically the same results by just using Boyesen reed petals for a whole lot less.
