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 The previous version was outdated and no longer supported.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

Electrical heads up.

I posted recently that when my MY12 TE511 got hot it would not start (turn over). Bike ran perfect,
started fine cold or warmed up. Just when hot enough for fan to run, bike would start to turn over then
stop, as if battery was low, or mechanically binding. What I found was that the starter solenoid on the
print shows a overload, and when it is to hot this opens up, stopping the starter from turning. Initially
an amp clamp showed this, and jumping out solenoid confirmed it. Going to try a new solenoid, but believe
The culprit is heat conducting back up from starter, and am installing larger wire on solenoid to starter,
And all starting circuit wiring. Keeping speed up on these bikes seems to let enough air to run over
front of engine to not allow this fault, but the single track,1st gear stuff I have been doing really does
get bike hot. I know these bike are not really for this type riding, but have been surprised how well it
performs this slow speed stuff since the ECU upgrade and the EF coolant.

Would like to know how this turns out I just went though this on a long steep rocky single track after a couple of consecutive spills I found myself setting in the woods until my bike cooled then it cranked right up.
 
I am having the same problem with my 511 as well, it won't start when it gets hot. How did you go with your fix James?
 
I want to update my post from early November since then I have upgraded my ecu, muffler, front sprocket and added an oil reservoir as well I removed the oil overflow from the air filter box and I have no issues with the hard start or stalling my cooling fan comes on when I'm on single track but when I stop it starts right up as well it won't hardly stall even when jumping logs or climbing Hills you just hang on and it does the rest I am loving this bike now.
 
Hey Helga, I went with a Lithium-ion battery which has a much higher cranking capacity and it helped a lot but didn't totally solve the hot starting problem, I run race map II which one are you running? I hear there is a Race Map III.
 
I had my ecu reprogrammed by my local dealer with what they call the Akro map it replaces map 2 even though it will still have the same display on the lcd screen it is not the same program any more my dealer calls it akro tune because if you buy the akropovic ehaust system they put that tune in also some people call it race map 3 some call it bmw race map but it is all the same and I recommend it I could tell a difference from 2 to 3 maybe another reason I am no longer having the hard start or stall out problems is that I have changed my riding style a bit I was running it pretty hard like a 2 stroke this is my first 4 stroke dirt bike but I started using more of the low rpm power not lugging it by any means but not screaming it either it just feels like the more I ride it the better it runs.
