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 The previous version was outdated and no longer supported.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

Two Factory Mufflers for 06 TC-510

Hey everyone. Brand new to Husky after coming off of KTM. Ran across an 06 TC 510 slightly used, and I mean very slightly on ebay and got a great deal. :cheers: When I picked it up from the previous owner ( he kept the bike in his house vice garage :notworthy:) it had what appears to be a factory open competition muffler installed AND an extra factory muffler that is Forrest Service approved, spark arestor. My question is, were all TC 510's delivered with two mufflers from the dealer or did I luck out and get an "extra"? Also, any significant differences to jetting if I switch and and put the forrest service approved muffler on the machine?
 
Aggie, congrats on the new purchase. Some '06's were delivered with the two mufflers you have, but not all. So, you lucked out. My 450 only came with the open comp muffler. I just picked up an extra spark arrestor type and will be using that this weekend. I will post up if it needs jetting changes vs the open one.
 
aggie*86, i have an 06 te 450, it came with an open muffler, but found out a year later, from my dealer, that it was to come with a spark arrester type muffler, so they sent me one free of charge. but i was not aware that the tc models came with 2 muffler cans.

Thanks for the info. Waiting now for a report back on how the spark arrestor type may affect jetting.

I've jetted TE250, 450, 510, SM510s... Leo Vince, Arrow with and without spark arrestor. Not a whole lot of difference in jetting needed in my humble opinion.

Of course they do need to be tuned up for the environment, riding style, etc. The AP leak jet is the biggest issue - on/off/on/off the throttle needs a smaller leak jet than the occasional blip of the throttle. Assuming you want good throttle response when the throttle is opened quickly and not load up with too much fuel.
 
Coffee, thats good scoop. I always make changes one at a time so if I dont like it, I know how to get back where I started easily. I added a JD kit with the "basic" installation as recommended by JD. I havent had it out for a spin yet. As soon as I'm happy with the carb settings I'll switch ove th the spark arrestor muffler. In the past on other bilkes the "basic" JD setup has worked perfectly fine for my riding environment and style.
 
While you have the carb apart be sure to note the jet sizes - pilot, main, leak, AP arm distance, etc.

AP arm distance, some call it 'timing' for some reason. It determines a lot of things regarding the AP.
