    I don't know about power, but the crossover definitely reduces noise on the GS.

    I noticed they place the cross-over where both headers are the same length. When two exhaust headers with no cross-over are joined into a single prior to the silencer - does one header being longer than the other before the merge effect performance of one jug over the other? How do you 'balance' the effect if it does?

    There is the existing crossover at the front, which I'm going to bother eliminating.

    I was referring to the "Y" that I made to bring the right side to the left side.

    Once again, i invoke what i heard from the the mouth of Paul Rooney, whose opinion it was that the crossover pipe was there for when the bike was at idle. It was an idle assist, for whatever reason.

    Thi came up because i noticed he'd cit his off on the R65RR and welded plugs over the holes, and i wondered why. He said it wasnt built to go at idle, and every little bit cuts weight :)

    Agreed, I just got the bike a couple of weeks ago aftet years of lurking here and I have to say i'm impressed. I've got a head full of ideas and plans for it...fortunately I have a very good platform to build from. previous owners have done most of the mods I would have. I intend to give it a more "rally" look and the ergos need to be adjusted and it's requires mods to enable it to become a submarine..mechanically wise she runs like a dream.

    Extended swing arm
    Cams upgraded
    Pistons coated
    6000 miles on engine
    Hpn transmission
    Hpn style frame
    1040cc
    Etc

    I feel very spoiled and I'm loving it :clap

    I like. :evil Where did it come from? Who built it? Got any close-ups of the frame work? You realize we're not going to let you off the hook with one photo, right?

    That's a good enough reason to have it for me. I must be one of those boring BMW guys.

    +1 I can't believe that in this day and age people still build motorcycles without telling the world about it on the internet. Selfish jerks :lol3

    DH... any other pics of that front fairing or do you know what it is? From the angle I am wondering if it is a lynx one.

    A wee bit easier to work on than your prior bike? No more 4 hr job to change carb settings or all day valve checks :eek1. Welcome to the world of old school simple. I gave up big orange this winter and moved back to something I enjoy working on.
