    Ok, here is a small index of what to do to tune the 690:

    1. First, remove the power restriction on first and second gear:

    2. Second, install Accrapovic mapping, it's done by the dealer/shop after you replaced the exhaust system.
    It will alter the bikes fuelsystem so that it gives the engine more fuel as needed when replacing the stock exhaust system.

    3. Modify the airbox, remove snorkle completely.

    4. Install chip that will give the engine enough fuel when airbox is modified. Please report if you find anything.

    Ive not heard of that. You have a link?

    I have heard there is a wire you can modify so that 2nd and 3rd gear are not "governed"....any truth to that on a 690 duke?

    Can only find one exhaust system...

    Yes, you cut one cable to remove the power restriction on the first and second gear. I will try and update this threads first post.

    There is nothing to hold the airfilter in place w/o the snorkle component. It acts as a retainer which holds the filter in place.

    I used a paper clip, and struck it with a hammer to flatten a profile that would fit into the connector block which would then depress the pin's locking tab freeing it for removal without issue. Do not pull, or tug the wires out of the connector block as described. You can permanently damage the connector's body and the pin will no longer stay in place once replaced. It's a poor-man's pin extractor for home use.

    The paper clip works on both connectors

    the wire deal is EASY couple seconds to poke em out the back and reconnect. I can tell a little bit in the topend i think...

    Any new products out there?

    Mines been very fun. Half the miles since first service have been WOT!

    Very easy bike to ride HARD.

    My only real issue is the transmission and false neutrals. It was a bit clunky at first too but now the transmission and motor are much smoother(or maybe its me getting used to a big thumper). False neutrals have reduced but still happen occasionally.

    Overall very happy. Just want more aftermarket! ;)

    Can anyone tell me how to properly remove the airbox in a 690e.
    I would really like to utilise the space here if possible.

    Is some sort of pod filter then appropriate to use, if so what's recommended. It'll need an angle of some sort from teh carby.
    Would it be necessary to provide some sort of shrouding or is it ok just sitting there.
    I'm a bit worried an exposed filter might just be a pain to keep clean all the time.

    I do a fair bit of dirt but avoid deep river crossings.

    What other purpose would the airbox serve that doesn't come to mind.
    Do i need it for some obscure reason?
    Back presure, resonance etc.
