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 The previous version was outdated and no longer supported.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

250-500cc max bike temp

Hey Tim,

Not a WR300 but my TXC300 has seen a max temp of 279. I have a 1.6 bar cap and it was just barely boiling.

That is with the trailtech sensor in the crossover to the right radiator.

Later,
 
What temperature are you seeing?

These bikes are incredibly resilient. My 2006 WR 250 was run for over an hour in HS race practice conditions with no coolant. I pulled the cylinder to see if it was corked. I found no evidence of damage. That was 38 hours of use ago and it’s still running just fine.
 
With the trail tech sensor in the left side I have the yellow light set to come on at 200 and the red light set at 210. Climbing any decent hill they come on all the time, never boiling over. I talked with Kelly and he thought they read low. I have a infra red temp meter that I am going try so I can set it to account for the trail tech sensor.just looking for the max number.

Jake,
That switchback pic of FD is crazy, I would have needed my riding depends and a box of cleenex

That is perfectly normal. With the stock 1.1 bar cap, you are good to 228 without boiling. The 1.6 bar cap I have puts the boiling point at 235.

I wouldn't worry about anything until you are blowing coolant out.

That was a great set of switchbacks. :thumbsup:

Later,
 
I put the sensor at the outlet of the second radiator where it goes back into the cylinderhead. If I'm moving at all it never gets much above 190 even if it's 100 degree ambient. Last weekend I rode some nasty single track, 90 degree ambient, slipping the clutch, dead uphill starts over roots and ruts barely moving and it got to 230 without boiling over. Cooled right back down once i got moving again.

Any thoughts on the best place for the temp sensor?

WR 300
