  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

2010 TE510 + factory baffle = more power :)

Just thought I might share with everyone that when I put the baffle back into my factory can (its been cut down though) I seemed to have picked up some power plus cut down on some serious noise pollution as well :)

Since day dot the baffle has been out and never knew any differently. But since I have put it back in the power seems to be slightly better up in the higher RPMs and noise is purely airbox now. However it lacks a little bottom end, but the compression braking has also improved. Loving it :)
 
The bikes run a lot better with the baffle in, than they do with it out. They pull a lot harder throughout the rev range as well, and the biggest bonus is the bikes are much quieter.
 
Any change in exhaust flow requires a change in fueling. Tuning is essential to getting a performance improvement when changing the exhaust. Or intake for that matter. Everything has to match.

When I was messing with performance mods on my Harley, I learned alot about overlapping cam profiles and balancing the exhaust and intake, to better "suspend" the fuel charge in the combustion chamber at the critical time when both sets of valves were open. If your intake is restricted and exhaust is free-flow, you get backfires in the exhaust, and if your exhaust is restrictive and your intake is wide open, you'll get intake back fires that blow the carb out of the boot. I am ready to start experimenting with putting my air filter baffle back in and some baffling in my muffler to get back to a little more torque.
 
Yeah it would be good to have a dyno to test all of these results, would make tuning and experimenting alot easier.
 
just to be clear, what do you mean by factory baffle?
Inserts held by c-clip? in the US; stock is a spark arrestor. There are optional, dbkillers: 2.5" and ~8" (euro) that don't have a spark arrest or screen. Best Power I have found is with the Spark arrestor(09TE450).
