    I am all most done with my air box testing and will be posting pics soon.  About 6 months ago i was talking to brani at coober about building some performance kits and comatability with a pipe performance air filters and his ecu. He told me that the ecu could handle a pipe and an air filter no problem. He was realy interested in the mid pipe so i pulled one off the shelf and paid for it out of my own pocket and shipped it to astria for testing.  I will be shipping a new air box with mods to brani for testing in the next day or two.

    VP-1,

    this is fantastic stuff! I have my mid-pipe ordered, coober waiting to be installed, and will do whatever you come up with on the airbox. Crossing fingers that coober finds their ecu can handle  these pieces as it stands. Or maybe they can update the existing box if need be.

     

    Thank you!

    Haven’t had mine apart yet to compare but guessing all the holes in the back were added. Looks like from the factory. Not sure what’s being done to the lid but sure it’ll make sense once apart.

    VP-1, you’ve seen coober is selling drilled/cut airbox lids now? Are those your designs?

     

    Any word back from Brani on performance testing?

    That is what he used to make the maps for the ktm 390s and vitpilen. The air box stuff is done but i am working on a better pipe setup. Most of the exhaust availble are made to work  on a stock bike. These pipes are made with large dia tubeing and you start to loose big power when you open the air box.

    I’ve had it happen to me a handful of times. I checked KTM forums as well. Besides lots of kickstand cases I also found cases of clutches dragging. If the clutch isn’t fully disengaging it can cause the engine to stall when you clutch in.

    When I took delivery of my bike the clutch cable was WAY out of adjustment. I spent a few minutes adjusting it but never compared it to the manual spec for free play. I saw a few cases on KTM forums where guys said adjusting the cable and leaving the lever at the longest setting ended their stalling issues.

    Check your kickstand switch and clutch adjustment!

    I posted this on another thread, but I think this needs to be spread around

    “This happened to me twice. Both times after a fill up. My suspicion is that it’s choking out due to over filling the tank.  The way I picture it, is that fuel is splashing into the vacuum port(?) for the evap canister, creating a bit of an air lock similar to holding liquid in a straw with your finger on the end. It could be many different things and this is just an idea I’m having without looking at my bike to see if it’s even possible.”

    this has been verified my the OPs mechanic, so the moral of the story is that you shouldn’t over fill. Running out of fuel can be really hard on fuel injectors.
