    Just got me a new bike. 2004 FLHR, with 95", SE Heads, SE204 cam, HR 45 carb, SE Race Tuner.

    Seems to me that it over carburated with the HR 45. Would think the HR 42 would be enough. I figure the Stealer just sold the previous owner a bill of goods. They also installed a SERT. I thought they were only for EFI bikes? Also, it was a CA bike, so it has the extra special CA features.

    I've got my Service and Parts Manuals on order, but thought I could pick everyones brains in the meantime.

    Thoughts on this setup?
    Any advantage to the SERT?
    Any advantage to the California emmisions stuff, or could it be removed readily?
    I have the SERT CD and cables. Is this something I can hook to my laptop and program the ignition map?

    Lastly, this is my first bike with dual calipers up front. The front brake lever pulls much further than any other I have owned, before braking begins. I tried bleeding this weekend, but to no avail. Is there a way to firm up the brake?

    Questions, questions, questions.

    Thanks gang.

    boy, you got me on the SERT, I would not understand why it would have one, are you sure it isnt a screamin eagle ignition or something else like that, the california emissions is a charcoal canister above and front of the rear wheel with a hose to the intake and catalytic mufflers, the hose going to the intake doesnt hurt anything but I would dump the catalytics(I bet they are already gone) You can bleed the brakes, in 04 they still used dot 5 and I would change out the fluid that ususally helps quite a bit and you could also switch to braided cables, that would also help a little and a switch to Lyndall pads would also be an improvement in braking, Todd

    Not having the service manual yet, and still finding my way around the bike, I couldn't tell you for sure about the ignition yet. Two CD's came with the bike. One says "EFI Race Tuner Kit", the other says "Ignition Race Tuner Kit".
    There are also 2 sets of cables and 2 adapters for the cables included. :wtf:

    It runs pretty good, but I can't help messing with stuff. Got to take it apart to see what's what.:D

    Stay tuned.

    45 is probably too large but it won't be a problem you may pick up a few hp up top but loose a couple down bottom, doubtfull that you'd notice any differences, 42 would have a better throttle response feel but the Mik is a good throttle response carb, I'd leave the 45 alone.

    For the California emissions stuff, leave the hose that runs from the intake to the charcoal canister in place, remove the canister and put on a small Custom chrome filter to be a catch for oil. Then cut back the line from the backing plate and tie in the head breather system to this hard line. It's molded to the frame, and works perfect and now you've moved the oil mist from the intake to the little filter. Cleans up the intake and removes oil drip.

    You must have a tuneable ignition not the SERT which is EFI only.

    It may be programmable by PC, for changing maps.

    If it runs good, leave it alone and ride it....
