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 The previous version was outdated and no longer supported.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

2000 TE410 - Backfire/popping on decel?

Hi all,
Long time lurker, first time poster.

I didn't know if I could post this here or if I had to go into the "vintage/left footer" sub forum... 2000 cant be vintage.. LOL

Anyways i have a 2000 TE410 that I just got back up and running after putting a new stator/flywheel into her (corrosion sucks).

She runs like a champ now, power is back... I can only imagine how long the stators been going out...

Once I get off the throttle, I get a LOT of popping on decel. Its more annoying than anything. Nobody behind me ever sees flames or anything, but its really really annoying. I been searching for jetting information for the bike, and all I found was some other forum to adjust the mixture screw.

Does anyone have any advice on what jets to run in this bike or what clip postion to be on? Or the best way to "use the fuel screw" to relieve my popping?
I mainly run between 600-1500 sealevel.

Thanks
Tim
 
I've no idea what carb is on that bike, but the general concept is to make the pilot circuit richer. It is also a possibility that there may be a leak in the exhaust system, but usually the fix is to make the bike idle richer when the throttle is closed.

Adjusting the fuel screw / pilot jet for max rpms when the bike is at idle is what I do. The rpm changes can be subtle to detect and easiest for me to detect if I keep lowering the idle speed.
 
Without being at my buddies house (where it's stored waiting for weds trip to WV), i can't tell you. I am pretty sure it's a Mikuni.

So can you explain a bit more about using the idle & fuel mix screws to richen her up?

Sorry i am not totally follwoing your description....
I set everything back to the manual specs when I got her running last week. (like turn mix screw all the way in, and then out 2.5 turns)

Does turning out the mix screw allow more fuel?

I do apologize, carbs aren't my strongpoint, and I am the only husky in our group.. LOL
 
On my Keihin carb, turning out the fuel screw makes the idle richer, and putting in a larger pilot jet makes the idle richer.

It could be that you Mikuni works the same way, it would be really nice if someone could speak up on this topic that knows more.




If it is a bike that does not get used a lot, the fuel could be stale. That was the case with our little xr100 we had. It would not get used often and the after 4-6 weeks the fuel would be stale, and would require the choke to be out much longer than it should - until the newer fuel got to the carb. Since then we have been using Stabil and that has not been an issue even months later.
 
Ahh... well if the bikes are getting stored longer than a few weeks, gas is drained out.

I appreciate your assistance though!!!
 
The carburator for the 2000 Husky TE410E is a Del Lorto. They are kinda strange. Honestly I hate them but I remember putting a Keihin carb on my old 94 husky and it ran awesome! My 98 TE410 has a DelOrto pumper carb. I hate it too but it works. Carbs are one of my weak points. I don't know what they are using on the new Husky's these days.
