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 The previous version was outdated and no longer supported.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

Recently purchased an 08 te450 low miles that wasn't ridden very hard but has some updates... power up kit.oxyge sensor removed..looks a little rich by the black on the exhaust tip but im fine with that .. If i like the bike enough ill get an oversized clear tank over winter... I have a trail tech mounted instead of the stock speedo --- The Temp sensor is on the hot side after waterpump before the radiator... On a hot day,80 /85 degrees, on the road im 165-185 -- IN the Woods im running anywhere from 210- 235... 10- 25mph , Good flowing single track - I did see 235 at one point stopped for a bit waiting then pretty much maintained in the 220's - Im not exactly sure how hot is to HOT! Although the bike always ran perfect { only did 1 30 mile single track ride with it so far... I love this motor...xr 650 smooth tourque on bottom but runs like motorcross 450 up top! its geared perfect for the woods,1 down from stock in front, may be a little short on the road , but i can deal...I had a 2010 wr250 2 years ago and loved that motor as well!

Now i understand after the motor before the radiator the temps is a little higher --- It did puke spits of antifreeze on the motor out of the overflow bottle not bad though just a little..I have the stock radiator cap, i realize i could do Evans, and a highflow pump, and hose upgrades,,, Im pretty confident it does not have the stock hoses... they all look like they have been cut to fit.. and the radiator fluid is more of an aqua blue greenish.....But is there a seperate thermo sitch for just the fan or is that also which controls the ecu? and the location? I would like to switch the fan to leave on in the single track ,but i dont want to fool the computer unless thats not a problem.... Im feeling that it comes on a little late and by that point its already very hot... a quick burst of speed in the open cools it right down... Sorry if this has been discussed i looked! but i also know temp sensors might have changed locations with different years of fuel injection....
 
Drain your coolant, flush your radiator and put engine ice in. I have never had a heating issue in my 510, 2x 450's or 2x310's I ride hard ST in steep country in Australia often in the high 80's/ low 100's. I am also 250 pounds stripped.
 
Engine ICE? THis is good to know. Thanks for the tip. Next time I change fluids on my 510, that is what I will put in it.
 
if you are going to spend the money on engine ice, its a better investment to switch to an actual waterless coolant. check out the xf2 stuff from our own zipty racing..
xf2 will build no pressure in your system, hard to boil over that way. cafe husky users get a discount at zip ty as well..
engine ice is a good upgrade over normal coolant however, but i have switched everything to waterless now.

Thanks for the replies - the bike ran cooler the next time I took it out .. I will drain the system over the winter and go waterless - I feel if that fan came on a bit sooner it would be much less prone to running hot - I'm also on the hit side where my trail tech is Hooked up so it'll be a couple degrees hotter on the gauge
