    Hi all - new to the forum.

    I read a great post the other day by Richy1bravo on April 13, and it helped solidify the changes I want to make to my 2007 XL883 (I can't link this post b/c I am new to the forum).

    I plan to do pretty much the same series of mods, but i'm hoping those in the forum can answer a few questions i have:

    1 - Intake - I am planning the SE Stage 1 kit upgrade. my questions are:

    should i swap out the kit supplied filter with the K&N SE replacement filter? Will I obtain any more performance? and will i still be able to use my stock cover (i like the chrome cover i've got).

    Also, I read where one can simply construct the SE intake from individual HD parts. is this worth the hassle?

    lastly, is the "heavy breather" SE assembly something I should consider?

    2 - EFI upgrades: The Dobeck TFI seems like the way to go based on posts I've read here. I like that no re-mapping is necessary, so if i want to remove, I don't have to worry about reprogramming back to stock. Seems to give more tuning options as well. Are there any gotchas?

    3 - Exhaust - I am close to deciding in the Cycle Shack slip ons, model MXL-330, which I undertsand are niceand loud, but not as loud as the MXL-130's. Input welcome here on user experiences with either/both/or other recommended slip ons.

    I'm a newer rider, but am ready for more power on my bike. But so much ready to move up to a big twin. Besides, I have gotten attached to my Sporty, and love the way it handles.

    Thanks in advance for any input, guidance, or just shout-outs.

    Cheers

    :cheers

    Hi - I realized I never followed up on this post, so thought I'd reply now that I've had some time on the road after my mods were complete. Overall, I am very happy with the changes, but have a couple lingering questions.

    I did the stage 1 intake mod, and found the install to be easy, once I realized how to orient the new back plate. The harley directions were not very helpful, but other posts I found here set me staight.

    I also added the cycle shake slip-ons, model MXL-330. NICE!

    And, I went with the Dobeck TFI Jet Kit. After a little tinkering, and as others have posted here, I went with the factory settings.

    WOW - I am riding different bike. Where I used to feel like the 883 was pushing as hard as it could at 55MPH, now, i move from 55 to 75 with a slight squeeze of the throttle. The bike feels more stable at all speeds. So, this was a "harley tax" that paid some nice dividends. Most of all, I feel safer.

    So, a couple questions:
    - with the stock back plate that covered the back part of the filter removed with the stage 1, could this be an issue if i get caught in a driving rain? and should the filter be cleaned more often?
    - With the Dobeck, are there recomended sparks to use other than stock?
    - Does anytone have input on Dobeck tuning dos/dont's?

    No problem riding in the rain. You would have to cross a river to cause a problem.

    Stick with the stock plugs from HD.

    Check out the self help forum for some TFI tips.
