    Dry weight ain't worth crap. You can't ride em dry. I would be suprized if the Mille came in much under 500lbs with a full load of fuel. There is not that much less there than the Futura.

    I am pretty happy with the way my Futura runs. It has the big open Mille air boot. Restrictor removed. EVO filter. H-Pipe and Staintunes. Sounds freakin awesome and runs great. Every time I think I need to do something else to it, I end up asking myself "Why?"....

    Still needs a paint job eventually though.

    The Fut's "weight" is listed 30 kg more from the same old source. So 60-70 lbs and that's gonna be w/o the bags. You have to feel that weight difference every time you push one or the other around. The Futura felt like a feather compared to my K1100.

    Hello all... thanks for the replies.

    any maps that people are RUNNING would be fantastic to formulate my own... i'm trying to keep the values higher and keep it rich since my system has less restriction i'd hate to run it too lean and do damage. one thing i have found by running it at the current settings is that the low rpm power/torque delivery plus smoothness of engine is unbelievable for town commuting. I can pull out of corners in town doing 2000rpm without it chugging at all :-) :-) :-) the problem is the top end has lagg so not all good... and my in town ecconomy is 8.5L/100 :-(

    What I have found out is that if the idle mixture is rich the engine feels very smooth and nice but the fuel consumption goes up.
    The idle mixture also affects the cruise range so for best MPG it is best to keep it as lean as possible without having any obvious lean spots.
    As long as you are only in the lower rev and throttle lift range you don´t need to be so scared of burning anything.
    You will quickly feel if the engine accepts it or not.

    Hello.
    I'm an ignorant.
    Could you post pictures of the fuel pressure regulator connection points you said?

    Thanks

    hello Yotiro,

    fuel pressure regulator should be connected to motor vacuum (manifold)of the aft cylinder.

    Some bikes seem to have the fuel pressure regulator connected with the airbox by the small diameter tubes starting from the right front side of the airbox. This is not correct. The vacuum lines also seem to get britlle and prone for leakage with age.

    As the manual calls for it to be set up this way, it's likely all but those that have been changed by someone are plumbed this way.

    mine was connected to the airbox too... : /

    Those pressure regulators are made so that engine vacuum can help modify the delivered pressure. Clearly, Aprilia decided the Sagem system did not need this and hooked up that hose to the airbox.

    why on earth are ours not plumbed that way? Has anyone noticed a difference of replumbing it? Is there a possible vac line from the aft cylinder we can tap into?

    Mine runs just fine and can get over 50mpg if I try. Why ask why when all is well?

    if you are doing 50 mpg , i would not change it , for all others who have a high fuel consumption i would reccomend checking it .
    most vehicles i know have the fuel pressure regulator on the engine vacuum. Sagem is also used in

    imho fuel pressure regulators need to be connected to the motor vacuum, as can be seen in these 2 pictures. beats me why aprillia mounted them sometimes on the airbox. maybe we should let 10 people check their connections and also note their fuel use?

    from an engineering standpoint i would connected to the motor vacuum but aprillia is ofcourse an italian company.....

    because I get 35mpg out of mine no matter what! and I doubt an increase of about 800revs from a 1t down front sprocket would account for 15mpg
