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 The previous version was outdated and no longer supported.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

Simple test is to start bike rad cap loose. When it comes up to temp take cap off look at the flow, not the vibes shaking the water give a few revs and see the increase in flow. Replace cap let it idle and get hot to the point the fan comes on. Now ride it going thru the gears by the time in 6th the fan shuts off. This tells me it's working and air flow thru the Rad's is a main factor.
Lean jetting,poor quality gasoline(nothing from a pump is worth a crap,restricted exhaust systems greatly effect this also by causing motor to run hotter.
Riding at altitude because air is rareified (thinner)= less heat transfer.
Adding another Rad behind rear # plate w/fan would fix almost all of the cronic overheaters reason 50% more coolant capacity and 50% more cooling rad surface area.
Or just mount another fan on LH rad.
Lots of factors involved, not everyone rides the same or in the same environment therefore needs are going to be different and solutions will be different also.

Danbartol, I have a 2008 TE 450 and ride much of the same type terrain and elevations you do and have never had a problem with overheating. Fan only came on if I let the bike sit and idle for a few minutes, so I took it off about a year ago. I would definitely recommend getting a Y connector in there, it will help.

I had the rubber boot on my '06 450 come apart letting air in and causing a super lean condition. Maybe check the boot between the throttle body and head to see if it is damaged and leaking.
 
Hey Nederland got 8" of hail yesterday. Sure looked like a winter storm to me!

All kidding aside I appreciate everyone's imput, every little bit of info I get helps me diagnose the problem or gives me future knowlege.

Thanks, Dan
 
UPDATE:

I could no longer wait around to diagnose the problem, so I cobbled together the coolant hoses w/ some auto-zone parts and got her running.

I have the PC-V and Autotune completely removed from the bike, Husky power-up kit installed and am running an FMF Q-4 exhaust w/ quiet insert.

Following the great one's advice (George Uptite) I started the bike w/ the rad cap off and observed the coolant flow into the right radiator. That's pretty cool to do, the volume of fluid flowing is pretty big and obvious.

After that I capped the radiator and allowed the bike to idle until the colling fan turned off. That took approximately 4-5 minutes. As soon as the fan came on I hopped on the bike and rode down the block. By the time I got to the end and was turning around the fan was off.

So....................This leads me to believe there is nothing wrong w/ the bike and that the issue is w/ the PC-V or Autotune

Next step will be to install the PC-V and Autotune and run one at a time to see what effect each one has on the bike.


As a side not I noticed that the bike seemed snappier than when it ran on the Power Commander
