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 The previous version was outdated and no longer supported.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

Melted vent line question

So I have been doing battle with my 04 TC450 now for a week. She would not start one day last week so I immediately thought valve play check time. So I did the valve checks and found the exhaust valves seemed a bit tight (could not quite get the .008" feeler in there). Changed shims now three times and am back to original shims. After some head scratching and brain straining, I looked elswhere for problems. A quick visual inspection revealed one of the carb vent lines had somehow rubbed up against the exhaust pipe and completely melted. Here are the start/running symptoms I have.
She will not start normally (no choke).
If I choke her, she'll start but only idle with no throttle
As soon as I twist, she'll cough and flame out.
If I start her with choke and then cut the choke, she'll just die out instantly.
Could the carb have sucked up some melted hose spooge and gummed up the carb ?
Help please

Clogged up carb vents will make 'em hard to start. Are you sure the one that melted is now open to atmosphere and there's not a melted glob internal? We just had a similar incident at a mud-fest MX race where most of the vents became partially or completely stopped up with mud. The bike became very hard to start hot or even when it cooled down. When I cleaned out the vent tubes.... bingo! Your symptoms also sound a lot like a clogged pilot jet as well.
