    My buddy just picked up a set of slightly used Akropovic pipes for his 950..they don't fit snugly when bolted to the end of the pipes? They move back and forth and side to side.... Is there some sort of washer that needs to be here?? thanks

    That the gaskets are in place (item number 32) Often times they remain in the stock pipes.

    What Don said. I'd guess that's the problem unless there's some weirdness (highly technical term) with the threaded part of the color. Which seems unlikely since it hapens with both sides.

    Akros should come with those gaskets. But seeing as how they're second hand they probably got lost, forgotten, or are still rolling around in the bow he got them in.

    I suspect the aftermarket companies expect the installer to swap or replace (if defective) the gasket using OEM suppiers.

    If I recall correctly the install directions from FMF said to transfer the old gaskets from the stock mufflers. You just remove them using the appropriate tool(s). I beleive they were a metal gaskets that CAN be damaged during removal.

    I put on FMF's and destroyed one of the gaskets. So I put one pipes on without it. Seems fine. Do you really need them ?

    You "should" renew them whenever the cans are removed as they are crush washers...

    should replace them but I suspect most don't unless they destroy them during transfer to the new mufflers.

    NOTE: Yes gaskets should be used in the install. We are dealing with extremely hot gases. If they escape in the wrong place (under your butt, near the airbox, carbs, shock, frame, ect.) they can quickly damage or destroy anything near them. A bit like a cheap plasma cutter. :evil

    Yeah..you really need them...without them the muffler would rattle and spew exhaust everywhere..

    Called up the Corse Superbike and all is well..they have them in stock.

    Thanks for the info..:D

    Talking od Acraprovics, I have just ordered a pair for my 950, does anyone know whether I need to make any adjustments to the carbs?, I have already lifted the nedles one notch with the origonal pipes (running slightly rich) so I am hoping that the new cans will be fine at this, any thoughts??

    Check the bolts to be sure they are not too long and bottoming out in the Akra's flange before they get snug. Used sets sometimes don't come with all the proper hardware.

    Thank you for sharing your experiences with Akras installation. I ordered a set for my '06 KTM 950 Orange and beg someone to list installation steps or refer me to the reliable installation procedure if exists. I'll do the legwork:

    I guess I want to start with the 'no-air-box-mod' type

    Tools: (Any special shop tools other than 950 on-board set)
    1.
    2.
    3.
    4.

    Extra Parts and materials:
    1. Gaskets (manufacture, part number?)
    2.

    Any Other Pre Installation Category (For example, Elevation Considerations, Environment, Air Box modification or not, Any expected pitfalls?)

    Procedure:
    ( Note: this procedure is an example one; improve it please as you wish)
    1. Remove rear fenders
    2. Remove original exhusts and check for, save? original gaskets
    3. Clean head pipe ends and treat them with ??? if any
    4. Install new/original gaskets ( using tool X)
    5. Install Akras
    6. Check for loose ends and tightness, accuracy of installation
    7. Test starting the engine (expectations)
    8. Testride with baffles in (expectations)
    9. Install fenders
    10. Testride with baffles out (considerations, expectations)

    Thank you.

    Has anyone tried modifying the akropovic baffles/DB killers. Taken out the bike is to loud, in it's to quiet.

    I put fmf 4.1 quiet core spark arresters in mine. You need to drill the hole further back on the insert but besides that they fit fine.

    A normal fmf 4.1 spark arrester works fine as well.
