    I think I posted my final set-up which is a S/E breather, S/E Fatshotz (7 disc per side), SERT and V&H head pipes w/ power chamber. Anyhow on a group ride I through the mountians, flats, Interstate and local roads got an overall average of a bit more than 49 MPG with plenty of torque for the mountains. All that being said, later that week it turned cold and my wife and I decide dto put some miles on the bike. Well the 2 up riding and the cold weather took it's toll on the good gas milage but the preformance was great.

    I tried the Sert, had it dynoed. WAn't a happy camper.
    Got tired of paying to have it dynoed too.

    Got a 103 motor, using the PCV and want the Thundermax. And riding 2 up, I'm gittin 200 miles or so on a tank of gas.

    Did it loaded on this ride too.......
    My bike pulls really good with just the 103 engine......

    103 is a good engine plus you've added the cams which gives it even more. I wouldn't mind to have a thundermax and the 103 "hop up" kit from Harley but reckon I'll stay with the SERT and save up a few bills then maybe do it later. A buddy of mine put a 103 kit on his 96 plus some high compression, high flow milled heads and a V&H 2 into 1 exhaust sytem. Dynoed at 115 RWHP and 114 Torque. Got a fairly decent bark now.......

    Started with Woods TW6 cams, was gonna do the 408-44 but sold them to a buddy and put em in his bike with a tuner. Then got pipes and a air kit.
    Got some seasoned heads and jugs. Had the heads done to stage 2 or 2 1/2 and got some pistons and rings and gaskets.
    I don't want any heads or cams from Harley, don't want anything EPA on my bike.
    Tore it down one day and put it back together the next day.
    Then heatcycled it for about 1/2 of a day before I rode it.

    Now I'm thinkin about the 120R motor setup. A few guys around here has put them in their bike and is super happy.
    The guy with the Rocker and 120R motor you can't wipe the smile off his face.:gah:

    Read about the 120R in the last HOG magazine. Be hard to keep that thing on the ground. But I'd still like to have one........

    Was told by somebody that had one, you got to learn all over again how to ride yer bike.
    It has so much power you have to watch how you use it.
    The bike will run away with you.
    You can pass cars like there was nothin to it.
    But if you ride it right, its a exceptional ride. All the power you could ask for.
    And its build by SE not Jims.....

    When you do the 120 don't forget

    More Go means you need more whoa!

    You WILL have to change the brakes, and
    you will need a better clutch the SE spring or VPC's don't
    keep up, RIvera Pro Clutch or Barnett have stock pull and
    double the clutch plate area,

    Save up bucks for fuel and rear tires....

    That 120R puts more HP and Torque on two wheels than a lot of auto engines put on 4 wheels........... I'd hate to think you'd need to go to a softer compound tire in order for the brakes to be able to stop the bike in a decent amount of distance in the event you need to make (or attempt) a high speed stop / slow down. Probably wise / safe riding woudl be the best practice. Course that's a good rule regardless of what you're on.

    Yea I may just put some more miles on the Old EG standard and wind up rebuilding the engine to a 107.
    The 103 at my age will pull so hard that its not funny.

    Even with this tank I ride, I can pass like 6-8 cars at one time with no problem.
    Chucktx rode it once, said I need to do more work to it to outrun his bike......:rant:

    How fast do we need to go to git to 100mph. Then what........

    Good point. Just got to slow down again. Reckon I'll keep her about where she's at for a spell and then go from there. Like you were sayin about your age, I'm thinking abou the same way. Just exactly how fast do I want to go anyhow - at 62. Although at one of the local dealerships, I was talking to a guy that was escortin a '10 or '11 110 Screamin Eagle 110 Street Glide and he was 78. Told him he was my new hero. He throwed his leg across that rascal and excorted it out of the parking lot right smartly with the Crushers speaking somewhat clearly.

    Nothing wrong with having it if you want to use it.

    My 124 feeds the need and feeds on my wallet for tires, brake pads, new clutch, new primary chain, transmission trap door, full trans rebuild (twice)

    Yeah going fast isnt' cheap, but it's fun..

    Stopping is another thing... LOL

    CB I wouldn't mess with it to go 107, it's just 4 cui and you
    are not going to see the power go up to the extent that
    you'd like. JMO Ride don't wrench...

    Ya know I had the 408-44 that Scott with Hillside told me about a couple years ago. They didn't have the 555 out then. Talked to Bob Woods and he said to go with the TW6 I had, and my buddy talked me out of the 44mag cam.
    Been thinkin about if there was a better cam. The TW6 is great.:)
    Don't know what all the extra lift will give me.

    the 6-6 is good
    did you advance it?

    if not talk with bobby about getting the +4, you got a heavy bike
    and you are not a 100 kid on a sport bike kinda guy so more TQ = more fun

    a a6-6 with +4 will move the tq band down lower RPM...
