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 The previous version was outdated and no longer supported.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

Help. Up against a hard deadline to fix the carb on my TE 450

Sorry guys for the poor explanation on my part:


The fuel leaking condition is not present anymore. I think the carb can be ruled out as the swap resulted in no change


It's the other condition, Stumble/stall/poor idle that pops up after 5/10 minutes of operation that still exists.

I will check for vac leaks, but this doesn't strike me as a problem that would develop as the bike warms up/runs for a bit???? I know the rubber intake manifold often crumbles and dies but mine looks perfect.

Are there any other parts to check in the ignition system beyond the coil/spark plug lead. Spark plug has been changed to new (no difference)

Thanks.

No need to be sorry .. You explained it well enough in post #17 ....

Did your own theory not pan out?

Gents,

I put a bunch of new parts in this carb, checked adjustments ect.... No change, same symptoms as described in first post.

I changed the CDI to one from a known good bike. Again no change.

Finally, I borrowed buddy's known good carb. Again no change. symptoms persist

I have a clue to the problem condition that I will try to confirm tomorrow.......

When I changed to my buddy's carb, for the first five to ten minutes (from cold) the bike ran well and I thought I had the problem sorted. Then the problem surfaced. Now that I think back to when I changed the CDI, I think the same scenario happened. I thought I had it fixed but after 5-10 minutes the problem showed up.

I intend to test this theory out again in the morning with a stone cold motor and will report back.

With this new information do you guys have any solid leads as to what my problem is? Are there any ignition parts that are known to fail with heat or 10 min riding?


Keep in mind that if you throttle up through the revs the bike works great. The problem is only noticeable at idle or light revs/throttle openings.

Thanks again for your ideas and experience. My Baja departure deadline is within days.

Regards,

Bugs

Hey Bugs, Say hellow to my Buddy "Cody Winn" he'll be there too. I work with him here in AZ. He rides an 08 KTM 450EXC. Just ask him about having his KTM upside down in a 6ft. deep rut a few weeks ago riding with Timmy. It'll blow his mind. Have fun and ride safe.
 
Success! And not a moment too soon.

It ended up being a failed/failing coil. Today I ripped down to Mike's (Husky NW) as he told me he had a coil but couldn't get it up here to Canada overnight. Installed. All is back to normal as of 9:00 pm west coast time.

We leave for Baja tomorrow morning at 6:30 am! That is a little to close for comfort.

Thanks to all for your helpful advice. Café Husky rocks!

Over and out for at least a couple of weeks. It's Baja time!

Regards,

Bugsinteeth
