    Post the dyno graphs please Richo.:lurk

    Be good to see where it is making power/torque.:deal
    Interested to see if it's suitable for track racing - got a tired 654 (with Vortex/Akra) in the 'wet' bike that needs a freshen-up.:hmmmmm

    When i looked at big-boring the 690 (790) a coupla years ago, it was gunna involve bigger injector, valves and mods to oil galleries, etc. - not worth the money or effort for our class of racing.

    Richo, some time back I remember you asking around about potential mods for the 690. Would you mind listing who you went with and what has been done. Very interesting outcome.

    Basically, ktm 2016 Duke 105mm barrel and piston on a 2012/13 single plug longer stroke engine ( ie full 690cc from factory, not the earlier short stroke 654cc)
    AGAP 255 cam

    Screenshot_20190824-110935_Drive.jpg
    I think the cam was about $700 Aud landed.( from Sweden)
    Part numbers for the barrel and piston kit and the head gasket are in the other thread link. Cost was about $450 usd all up plus shipping, so about $750? . Locally the barrel and piston kit on its own was over $1200 with none in the country.
    Tekno Ti power bomb header pipe from Adventure Bike Components Aust off their fb page. Cost was $500 On sale
    The Vortex ECU was about $800 iirc, had it a few years now. Remapping and three hours on the dyno at PTR to suit the new engine and dramatically more fuel needed was $500.
    Kevvy Doyle charged $700 to screw the engine together, including reseating valves. Note , due to timing/ cam duration changes and higher lift getting the timing correct is critical. Someone contacted me to let me know what happened when it wasn't done right. Ugly and expensive. Unless you've got experience and know what you're doing, get it done by a pro.
    Kevvy is happy to do others too if anyone is interested, let me know and I can put you in contact.
    2 new intake valves, $120 each I think?
    2 new rockers, @$165 each
    New timing chain, $65

    Think that's about it.
    I could sell the old 654 which is still running like champ to offset, but will just stick it on the corner of the shed for now.

    Oh yeah. . the later engine was $ 2500, from a wreck. But came with full loom, complete throttle body, throttle tube and cables, battery box and fuse block etc. Lots of stuff I can sell off as I won't need, let me know if anyone wants anything.

    Awesome thanks. Love reading re performance upgrades.

    Yes, always best to get performance cams dialled in. What i had to do with A/M Chev cams with offset bushes.

    Corresponding spares is a good thing.
