    Here is video, but there nothing special on trail ride.



    Then i found some triple pipes on this forum and bought them.

    Here you can difference between hauck bigbore pipes manifold and speedwerx pipes manifolds. Lot of better design on speedwerx.

    Hahah

    Well, speed corrects errors so it was time to get more power to this beast.
    Those speedwerx triples fit pretty good with reverse. I need to relocate battery, because pipes take a lot of space.

    Changed weighs to 8dn if i remember right, stock clutch sping with shim. Secondary spring also changed, but i have no idea what it is, all marks are gone.
    Changed mainjets to 165, i have to change pilotjets, but it is hard to get them so i'm still waiting my order..
    First test ride wasn't succes, sled bogs with full throtle. I have to figure out why...
    But couple pics, because pictures are nice.

    It is pretty tight, but it fits.

    And something special, can you guess?

    Nope, those are bushing for shocks. For stock front shock and others to fox float. I have seen couple pics of fox float mod to pro-action, but i don't know how they create mounting.
    That's why i decided to make some special bushing.

    Everything started here

    And here is outcome, with some billet wheels

    I have no idea how much i have to use pressure on that float shock, but it will become clear by testing.
    I think that there is different shimming on that rear skid fox float because, shock is much more sensitive on high pressures vers front floats.

    Hello,

    Some update for this tread.
    Last winter sled worked pretty well, i went to one hill race. I was third with old Yamaha, it was funny. I was beaten by 1100cc turbo arcticcat and 850 skidoo or lynx, can't remember.
    Jetting is little bit lean so i have to check it before winter.

    Always have to do something new for every season, so i bought a box full sh*t... Ofc everything is broken or modded...
    Some pictures:Bigbore_motor.jpg Notice those cylinders, two 73mm and one in the middle is 74mm... and steel plated...
    hauck73broken.jpg Here is reason why someone changed that cylinder
    shit.jpg 74mm stick cut
    ruined.jpg Something what i have to do new, can't save those anymore, can anyone guess who made them originally?

    Those should be silencers, but it is hard to even regonice. I will do new silencers when i have time. I have done little airbox mod for 38mm carbs, will post pics later.
