  • 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 The previous version was outdated and no longer supported.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!

Remove spark arrestor? Any gains or just noise?

I pulled the sparky on my 09 te510 and it was louder...big surprise, huh? So has anyone got actual data on whether pulling the sparky helps with power at all? I'm guessing that even with my PC V it's going to lose a little on the low end and pick up a little on top (don't need anything there, IMO)

What say you?
 
I felt like I had gained a bit more power throughout the range on my 250 when I removed the SA. Maybe it was the extra noise playing tricks on my mind... Some real facts/numbers would be nice as I was wondering this as well for awhile.:thumbsup:

Probably because it was either too rich to begin with or the SA was stopped up.
 
There is no big difference in power if you have a well designed / clean SA. Modern SA perform remarkably well. The wifes tale about more power was from the 70s when we had to use poorly designed SA along with dirty burning oil. To compound the problem, most ran their bikes too rich to begin with. Husky used to come jetting rich from factory so the bike wouldn't seize during break-in.
