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 The previous version was outdated and no longer supported.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

2010 TE 510 Overheating!

About the only general input I can give - peoples schedules are a bit off right now. You may get more information in the coming week.
 
Give George a call, he's been talking to Zip-Ty about their bikes running hot. Maybe they have some solutions. 1 714 540-2920
 
From previous post I know you to be a fastidious and careful owner so we can eliminate bike abuse. All that is left is there is clearly an issue with the bike. Some tinkering at the margin with a Y pipe, better hoses, higher psi cap and waterless coolant will assist. However, I feel there is an issue behind this and I would suggest you take it to your dealer to run some diagnostics on her.
 
My bike (09 TE450) started having the same problem after I installed the autotune, it never once overheated before autotune and accepting trims, I think its running lean at slow rpms and little throttle.

This is great information. Have you simply set a richer afr target?
 
Very Interesting!


once I get new cooling hoses i plan on testing the bike w/out the PC-V +Autotune to see how it does and establish a base line.

If that goes well, then I'll connect the autotune again and see how it does.

sounds like a good thing to investigate- could be PCV/AT set up and such- I don't have PCV/AT. I would set the PCV/AT to a "zero" map from what people have claimed that eliminates its effect- then test diagnose- so see if the problem persists.

I don't think all this trouble with heat and starting has anything to do with not having the best possible mods, I think it is something basic to the bike that has gone wrong or is out of adjustment. SO I'd eliminate the PCV/AT because that's just one more thing to the equation for now.

Good luck Dan and the party is not over- there's just an uninvited guest:thumbsup:
 
Let me dog pile on with overheating problems. 09 TE450, OFG Rad guards (at first). When riding, well putting around with the wife, on glorified fire roads, @ around 3500', I ruptured the small upper hose between the rads. Fan and waterpump was/are working. Dealer thought it was bad batch of hoses of late 08/09 so I replaced using only single regular clamps. Later the water/antifreeze pushed around them and leaked, so now double clamps. No ruptures so far. That low speed overlean condition is interesting.

That was unreinforced fuel line the factory used, that needed replacing. I used radiator hose from an automotive shop with regular clamps, no problem at all.

Before everyone piles onto this 'lean' theory, it is only a theory. Further work would need to be done to really dig into this situation. Usually in these types of situations people tend to get bored or mad long before the entire situation is understood.
 
Man that is just a bad picture all together. I feel for you man...really I do.

But that is like rubbing salt in a wound.:censored:

Keep us informed on your findings. But promise no more pictures in bad taste.

:cheers:
 
Here you go, earlier that day in a happy moment!

I'd lean towards water temp sensor. Does the fan come on?

I was sitting on my bike in front of George's trying to get it warmed up to put the iBeat on it and it took a while to get it hot enough to adjust. Fan never came on.

I agree with that statement and in my case I need to dig deeper into how the PCV and Autotune work, I'm not exactlly super EFI literate however when I look at the trims from the autotune it looks like its leaning the EFI out everywhere and more so in the lower ranges. I am going to start over and load the basic map for my bike and not run the autotune and see if it still runs hot/boils over.
 
Last weekend on a ride over the Sierra Mountains my 09 450 te blew the stock crossover hose at a bit over 9000ft. I was able to do a repair in the mountains and kept on riding to the final destination and replaced the hose with fuel infection line with easier hoseclamps.

I found that my overflow catch tank expanded enough to have a few tiny holes to let ALL the water out and my fan is not working. Is there a fuse for the fan. Could the temp sensor be defective?

09 te 450 that has all the smog removed stock efi settings.
 
The fan runs off the same fuse the headlight, brakelight, turn signals and speedo run off of, at least my fan would not work with that fuse blown.
 
dude get back to the water pump. my impellar sheared in mexico on an ugly trail ride, stream water kept me going to the finish, I was ready for pee if I had to. I rode a couple times after that still not knowing the root of the heat issue, finally a couple weeks later I did a sanity check and pulled the cover off the pump and found my impellar missing blades the nut and the center stripped with the impellar shaft spinning inside it. installed the new impeller and all has been good. Its another good quick trouble shooting thing to do on the list. R
 
Done!

I looked at the impeller the other day and it looks fine. Even cycled the kick starter a few times to make sure it was spinning w/ the engine.

All was fine.

Thanks for the suggestion.

PS how do you know if you have the High Flow pump or not. I thought the 2010 models all came with it stock, but am not sure.

The actual impeller looks pretty weak from a hydrodynamic point of view. The Impeller blades are square and flat, not like the nicely curved ones of my KTM 950.
