    Placed order this week, looks good fellas!
    Ned, any sense on how the stock 2 into 2 power curves compare with the baffled 2 into 1? Probably a good baseline test right? I know you had to be selective with your dyno time, but just curious.
    Your hard work is much appreciated.

    Were they with the modified stocker (with h pipe) or with the new Nedie special?

    True. Honestly, the takeaway point for me is that the 2 into 1 runs about the same, or a little better, and I have never had a complaint of a lack of power on the LC8's, so that's good enough for me. I do have a complaint of too much weight, and it meaningfully addresses that, and it opens the option for the tank and so on.

    I'm far from an expert on this subject, but my sense is that end-can flow is not the major issue in LC8 power. Baffles obviously slow down the party by a few horsepower (which is pretty meaningless in the scheme of things) and stockers are probably (having dissected a set) along the same lines... but I don't believe that there is a huge amount of power to be had even by going to an open pipe.

    All the options I've run, baffle in, baffle out, remus, neptune, and stock (on the 990, the dyno is down right now so I don't have a final run of 990 stock vs. 990 2->1 w/ Remus) have been within a 6 peak hp range, with minor fluctuations in torque and delivery. In the scheme of things, the best run vs. the worst run, wouldn't ride all that differently in the real world, if it was a good road and a nice turn, you'd have a smile on your face with either one.

    That said, the best run came on a 2 into 1 (although, as Nowwhat has pointed out, the test methodology is not perfect).

    The most recent runs were with the production item (with no crossover pipe).

    Good work, Ned......this is a secret pre-production version :augie , and it's very, very good. The final ones you folks are getting are even nicer, with a proper thermal coating and such. :nod

    Hey Ned, any more progress on the side fuel tank???? I've made the conversion to the single system, just waiting for a the tank now.

    Yes. I've got a sample from a vendor which looks good, we're working on getting the design production ready (parting line for the mold, correct draft angles, etc) and I spent last Sunday test fitting a CNC (wooden!) model I had made to both an Adventure and an SE.

    Like a fookin' moron I didn't take many pics (other than super detailed ones for fitment). But, here's one:

    It can't move fast enough for me, but I'm trying to make sure I get it right the first time around, because there's no way in hell I can afford a second pass. :lol3

    Hi Ned.
    I notice that the SE in the pic has a pillion footrest hanger fitted. Just for your information the UK bikes don't have rear footrests. (Mine doesn't anyway) so a bracket might be needed perhaps.
    Looks good to me though.:clap Quite large. I reckon it would hold a fair bit.

    What's not to love! :lol3

    Regarding the pillion pegs, we'll have an additional kit for that purpose. About half the US ones came with pegs, about half not. We'll try to keep the cost as low as possible.

    Ned, as per our discussion, I tried the two-into-one configuration 1st with my stock catalytic converter can and SAS. Bike ran smoothly, but seemed a little "constipated", and the engine ran hotter then usual, with all the exhaust going through one catalytic converter. So Stage I testing not satisfactory.

    Stage II was after having my blacksmith, Smithy 1, core out the center of the catalytic converter, again keeping the SAS and stock jetting. The bike runs BEAUTIFULLY! Very powerful through all RPMs. No surging anymore (had a little before at constant speeds). Engine running normal temperature, and the can no longer "glows". Even with the baffles retained, the stock can, with the converter cored, flows freely.

    [​IMG][​IMG]

    And, quiet as a mouse, because we left the baffles in the can. Good for stealth dirt rides in the woods!

    So, for now, I'm happy. I have room for your reserve gas container, or the one the Smithy 1 is making for me.

    Stage III, which was to get a single after-market exhaust, doesn't look necessary for me, since I like the way the stock can looks, and it works like a bumper, it's so strong.

    I got the email today that my 2-1 has shipped. Whoohoo:rofl
    I might lash up an aux tank out of a CO2 fire extinguisher I have in the garage.

    WOW! I notice no power loss, whatsoever. Maybe it's just my head playing tricks on me, but it feels a bit MORE powerful!!!! Holy Crap! I am digging this setup.:clap :clap :clap :clap :clap :clap :clap :clap

    I am especially digging the fact that all that heat is no longer cooking my rear shock reservoir.
