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 The previous version was outdated and no longer supported.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

Hot Husky's at the TKO

Leaves in the skid plate? ....

That fire looks really weird ..

If you look at the entire sequence, the first photo looks like a radiator issue and steam ... After that, the flames appear ...

So how did they put the fire out? Most fires seem to melt a bike quickly ...
 
About 2 threads down you'll see lankydoug's 'TKO' thread that has a great video of the race.

Read about the race format before you watch the video and it will make more sense.
At about the 4:20 mark you'll see the Redmond event...It looks like a hose splits or comes off sending coolant eveywhere. At that point I don't think anything was on fire until the coolant hits the header...and then things get interesting!
 
Four guys from our club made the saturday cut, two of them, mark patterson and Danny Pressley decided not to run the sunday race because they are leading GNCC points in their classes. Another one got cut after the first round on sunday, but riding buddy david scraggs almost made the final 10 finishing 12th. This is pretty amazing to me, this guy does not even race and he rides his bike on the street!!
 
Whoops! Maybe he got 14th, I just know he was 2 spots from qualifing. I did not get to go this year, hated to miss it, was in Illinois for a boat race. Unfortunately, a lot of our trails we ride on resemble what they race on in the TKO.
 
Its sure looks like what was mentioned a blown radiator hose, non-aqueous coolant atomized and in vaporized cloud then light off.
Seen the same in the aerospace world with cracked or pin holes Hyd lines, the fluid is really quite stable in proper fluid form but when atomized from pushing through a small orifice at 3000psi it will flash burn like a torch if it has an ignition source. (Talk to the farm guys about grain in particulate/dust form, same thing)
 
I think we can all agree these west coast guys don't know what they're doing! :p Just playing, but is worth mentioning most people here don't use Engine Ice or similar type of non-water coolant. Maybe because we don't need it and guys in hotter areas do? Andrew Delong blew a radiator hose too. I saw that as well and it didn't ignite. Maybe since he's a east coast racer he just uses regular old coolant?

btw, I do think if you look closely at the video you can see the leaves burning and that's the ignitor, not the header.
 
OOOH, scary moment! Sexy little red head has a hot temper in the dirty south. Looks to me that he blew the cross connect hose and the coolant ignited on the header pipe. The flash sent the fire to the wet leaves on the ground and was burning the coolant.

This fire scares me as I also use this "devils cool-aid" in my TE.
Ranger: "How did this fire start?"
Me: "Uhhh, Bike exploded".
Ranger: "Do you realize how many orphaned baby fawns you created with your dirty, coal burning, oversized carbon footprint machine?
Me:" Uhhh, I was on the trail, then boom".
Ranger: "Put your hands behind your back"!!!

Cool looking video ...except too much orange ...

I don't need that non-water coolant for sure ... I'd never wanna risk that explosive event on my bike ...
 
I've currently got Engine Ice in the race bike...and since I'm not actually riding it I was thinking of the safer route...

Don't want to start a full on coolant thread...but what works best outside of the non-water based coolant realm?
 
Just to put this fire out (ha ha). Maybe we should not use gas or oil those things are flamable too.
Straight up, Its a low probability, probably a one time incident. How many of these incidents have happened with non-aqueous coolants. At this point who knows there has been no data collected on the subject.
Thats the only time Ive ever seen it among us moto folks and the ZipTy team guys have been using it for a while now.
