Is kbryant Kerry? If so, hello, we actually met once, briefly, quite a long time ago. A tuner from the Midwest named John Golden was friends with some of your employer and he made a brief introduction. I don't even remember where it was. Likely wouldn't remember any of it were it not for the association with the E Series mufflers. I had them on a Road King at the time. John liked them a lot too. John made a comment about always being able to tell if a bike with E Series mufflers had been tuned because you'd find the hole drilled in the middle for the sniffer.
Just one of those odd things one remembers.
If you can and are willing share more on this evolved version of the mufflers? I always liked them for being something that could be used on true duals without losing the bottom end as much as with others in their day. Also liked the sound and look. But they were the best performing muffler when used with true duals on a bagger that I knew of. How does this new iteration compare with what came before?
10-4, that's me. John Golden is great guy and good people. Definitely made an impact with the original E-Series. Very similar to the contributions of Jerry Branch, Joe Minton and Mert Lawwill with the original SuperTrapp H-D lines that we developed back in the early 80's. All good people.
When Fuel Moto graciously included us in the venture of bringing back the E-Series with new knowledge gained over the years through trial/error on the street, track, R&D room; endless dyno testing, flow bench testing, prototyping, tooling design, CAD design, etc.; both companies were all in. This was a very intense R&D program to bring back an improved version of the E-Series that would work best with todays motors and FI. I mean back then, we were dealing with 40 hp 883's and the nastiest "street" motors we were dealing with was Merch and making maybe 130 on a really good day. Back then you'd have to slap on a Mountain Motor Core, a ton of discs, and open end cap to get the flow required and of course motors making that kind of power was not very common-place. Now-a-days, 115 - 130 hp + motors are pretty common place and we wanted to keep that in mind (as much as working with stock and/or lower hp motors as well). We looked at the ease of adjustment, tolerances, and reliability of adjusting/changing the disc stack; maintaining shape and perfecting flow transition from the inner core -to body cap - to discs. We looked at increasing flow, while still maintaining velocity, within the required disc spacing. We wanted more performance and a wider band of tuning, while utilizing less discs and not requiring an "open" end cap. We incorporated an adjustable "blank" disc that allows you to simply move its placement within the disc pack for tuning within the same overall number of discs provided; such as dual systems whereby you may benefit from increasing flow to the right side muffler and lessening flow to the left side muffler. This also allows more convenient changes to be made for throttle response, power band, sound levels, a/f curves. We changed all internal components to stainless steel (obviously the entire end cap assembly/hardware are all stainless steel as well). In total, we made close to twenty changes/revisions to my original design. All these aspects must be coupled with well thought out companion parts of the overall exhaust system design as well. The new Fuel Moto E-Series incorporates all the things we have learned and thoroughly tested since the original model, along with a great support program. If you liked and/or knew about them back then, you'll love the new version now.
