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 The previous version was outdated and no longer supported.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

Radiator hose clamps

I just got back from an awesome weekend at Jimmy Lewis's camp in NV. While there, we did some drills that really taxed our bikes and the cooling systems of some of our bikes, not mention us :censored: and our egos!

The hose clamps that came on the 2011 449 are absolute junk once they have been messed with. These are the ones that don't have slits all the way through the clamps but just indentations for the worm gear to grab. They are fine when tightened once, but if you mess with them, the indentations crush slightly and the holding tension drops. While I didn't blow a hose I sure sprung a leak on one clamp that I had previously installed a Trail Tech Voyager H2O sensor on. I knew better than to re-use the old clamp but I did it anyways a long time ago and forgot about it. She leaked and that reminded me to change all the stock clamps with these;

YMMV but I suggest replacing the factory clamps.
 
I see why your interest in coolant was peaked now. What was your leak like? was it coming out from under a hose or through it?
If you use XF coolant, your pressures will be down in the 1-2 psi area instead of in the 10-20+ area. Other benifits include no corrosion, lower engine temperatures, never having to flushing again.
 
Bummer, I hope it didn't spoil your outing. I have been looking for a new silicon set of hoses for the 449 but I haven't seen any kits. I am also looking for a new Y fitting for in between the radiators, it would be a great mounting point for the temp sensor as well.

Didn't ruin anything, I rode her all weekend! :thumbsup:

Call George at Uptite for silicone hoses and Y's
 
I actually like those dimpled clamps as they do not seem to tear up the hoses. But you have to have good ones (like come on euro cars) and do not over tighten them.

I would say that any clamp that tears up a hose is too tight or the hose is worn.
Most people over tighten I guess...

I do too. I get the clamps from a VW parts store. The side benefit is the hex is still metric so you can use your regular T handle or whatever. Like has been said if the threads are crushed, chances are they were overstressed IMO.

What would happen if say you had a stick or something in your radiator that you were able repair trailside and you run the waterless coolant, but need to add fluid to. Can you add water to the XF if needed in an emergency?

that's the main reason I do not use any of these special coolants. I have many times had to fix a rad or hose issue on my bike or others bikes and refilled them from a camelback or near creek. I like the idea of the benefits but not the incompatibility. that and i ride in the NW were it is not that hot and little need for advanced cooling solutions. and I ride a 125 (165) that is nearly impossible to overheat.

I blew the hose right off the pump of my Husaberg 550 11 miles into a goat trail and used bailing wire to clamp the hose onto the disscharge spigot and it worked better than the stock clamp. It all boiled down to quality after market . :) ha ha

Yes, mixes with water no problem. Looses its non corrosive qualities and some of its high temp, but mixes and is completely compatible with water. :D

I used to use EngineIce, but after dumping what looked like 140 weight oil, I switched to XF. EngineIce comes with water in it and once the water boils off, you are left with a thicker syrupy goo. XF contains no water and its fluidity remains the same. Both products cost the same. XF/Evans coolant is used in heavy earth moving machinery where millions of dollars are at stake and coolant failures need to a minimum. As far as corrosion goes, it doesn't matter what climate you live in, water corrodes aluminum and XF does not.

Cause the last thing we want is be in the middle of nowhere with a back pack full of gold from somebody's claim and throw a rod threw our cylinder....... Back to my margarita :) hahaa !
