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 The previous version was outdated and no longer supported.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

07 TC450 backfire

I found and bought an 07 Husky TC450 last week. Haven't had a chance to get it dirty yet but have managed to annoy the neighbors by riding it up and down the street a few times. It runs great and make lots of usable horsepower. The bike backfires on deceleration with the clutch out, otherwise it starts up easily and runs great. How normal is this? I haven't gotten it up to the temperature it'll be in the dirt. I'd appreciate any advice. Thanks in advance.
 
It maybe worth checking the fuel screw first and opening it up a quarter of a turn. or maybe stripping the carb down for a good cleaning and replace the pilot jet which is easier than trying to clean the old one.
 
Check your rubber intake union for cracks and air leaks. I just changed mine, after I noticed some pretty bad leaks. For a band-aid I had used RTV and it made a huge difference in the popping under decel. You could also have leaks at your exhaust junctions. Leaks in the intake or exhaust track will cause more popping than normal.
 
Thank you, have a new intake manifold on the way, also having valves checked for adjustment and will clean carb.

It's not that bad of a job to change, you can actually get it in an out without pulling the carb or airbox if you got good fingers. I used a small 8mm wrench for the three bolts and loosened both band clamps on the carb and the airbox. The left side bolt will not come out all the way, just make sure it is disengaged from the threads and rotate the union. Same thing when installing it, you have to install the left bolt in the union prior to installation then rotate it around until the bolt lines up, make sure it goes in strait of you could cross thread it (bad news)
