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 The previous version was outdated and no longer supported.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

TR650 overheating

deb said:
Thanks guys just bought my strada friday. today had a couple guys at coffee tell me about a bad thremostat only issue they had on terraand told me what to watch for. Wouldn't you know ran it into town and after a few stoplights on an 88degree day started to register 2bars short of hot and spewed some coolant and as I pulled into a parking space redlight went off. I only have 60 miles on my new bike. let it cool for only a few minutes and ran pretty well home as long as i was going still got a little warm at lights. Will call dealer tuesday. Didn't smell anything scary as I realize brutal on new engine to overheat. hard to see overflow but appears to be some fluid at bottom line.

Sorry to hear that. You would think by now the dealer would know about this issue, and proceed to burp the bike prior to delivery?
 
Deb, I see you found your way over here from ADVrider. I am certain you don't have a bad thermostat. Almost everyone has run into this issue, and burping the radiator is the fix. It will only take a few minutes of your time, and absolutely zero tools are required.

It seems as though many dealers are overlooking this during setup.
 
Thanks a little discouraging and I think I'll have the dealer fix it in case something happened to the engine during overheat also if they have to do this may make them more aware of burping. My hubby not too happy as I convinced him to let me buy before selling my vstrom. ooy

I took mine to the dealer for the same reason. Plus he's only a couple miles down the road. It happened to me twice so make sure they get a really satisfying burp when they do it so you don't get a second helping.
 
Did I do something wrong burping my bike?

I did the whole process with the bike upright on a stand.
Trying to keep the spillage of coolant down (this proved to be a wasted effort)
I emptied the overflow tank before opening the radiator cap.

When I opened the radiator I was surprised to find how low the level was given that the overflow tank was at max full.
I filled the radiator up so I could see the coolant near the neck.
I started the bike.
As the temp came up it began overflowing coolant out the top.
Then about the time the fan kicked on, it dropped significantly.
I assume this was the thermostat opening.
I filled the radiator again so I could see the coolant near the neck.
This time it was obvious that the coolant was moving and some bubbles were working their way out.
Then it began overflowing again, quite a bit too.
I shut it off and it puked out even more coolant.

Did I run it too long after the thermostat opened trying to get the bubbles out?
I don’t think I ran it more than 2-3 mins after the fan kicked on/thermostat opened.
Should I have just shut the bike off after the thermostat opened and not tried to get the bubble out while running?
Was I not supposed to fill the radiator during this process?
 
I just had to do mine today. A problem surfaced since I hit Georgia, and reared its head this weekend. I let mine run for a solid 5+ minutes when I did it, and it was 92 degrees outside. I never came close to overheating. I also didn't continue to top it off. I wanted to makes sure the bubble was gone.

Deb,

Coming off a V-strom I hate to say but you will be disappointed by several issues you will probably have with these bikes.
Look around here and you will find the fixes, most of it is pretty simple, but coming from a Strom (arguably the one of most trouble free bikes) it will be disappointing.

Sounds ok to me. About what I did.
 
Coffee,

Did yours dump a bunch of coolant during the process?
I was not expecting it to overflow so much, or to change levels so much during the process.
I have seen car radiators just bubble along for several minutes with no big level changes during a "burp"

I did not loose a lot from the radiator, when it started rising I turned off the motor. Then refilled when it was cool. I may have cycled it a couple of times.

My thought was that the engine is set up to run very lean, so it was getting warm quickly, and that was the reason the level rose so fast - and there really isn't that much water in the system compared to a automotive application.
 
I cannot find that post anywhere now. I know for certain I read it somewhere, because I even priced out the part and decided to wait.
 
They have a higher bar? cap on ebay may see about that. There is a post on adv rider about using a kx500 cap on a honda 650 but that is all I saw. My dealership is convinced it is the thermostat so we'll see where it sits on heat level after they replace it.

about thermostat. my mechanic said that of those bikes has many gà had to be replaced. says it is a manufacturing defect that sooner or later it will break too. but that Husqvarna will not release official warnings. We'll see!

a proposito di termostato. il mio meccanico ha detto che su quelle moto ne ha gà dovuti sostituire molti. dice che è un difetto di fabbrica che prima o poi si romperà anche a me. ma che l husqvarna non vuole rilasciare richiami ufficiali. Staremo a vedere!
 
I think the cap is the real issue and the burping is maybe just a Band-Aid fix that gets coolant back into the system.

After a bit of use I found that my coolant (like my oil) was over filled at the reservoir, assuming crappy set up I removed some to get it down to the MAX line.
When I opened my radiator cap for the "burp" the level was really low so it does not apear to be pulling coolant back from the reservoir.

In retrospective, perhaps I actually had the proper amount of total coolant for the system, but it got pushed up to the reservoir (perhaps because of a bubble or bubbles) and gets stuck there.

Now that I have the system burped I will be watching my reservoir volume.
I now have it set at the MIN line. Well, its set where the MIN line is, you just cant see it through the damn window.
I will also be looking for a KLX cap.

I call BS….it took me 2 days and removal of the body work to get that damn cap off. :D

Was this your first time burping it or your 2nd?
 
I agree ogre even semi stripped my first torx (they sure like the right size tool) to see if I could loosen radiator to get to cap. I'll be looking for another cap

First for me. I'm assuming my dealer did it at setup because I've had zero issues until the other day. I've also had no issues since. The TR is my only vehicle down in Georgia right now, so it is seeing lots of riding in traffic on 90+ degree days.

The cap isn't too hard once you figure it out. It really takes a whole lot of downforce to get mine to turn the last bit. Although, if you have fat fingers, you're just screwed.
