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 The previous version was outdated and no longer supported.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

Upside down TE250

Hi all, had a small incident with a tree whilst racing yesterday which involved me being semi unconcious and my 2010 TE250 being upside down on it's bars like a bicycle and still running. By the time I hade peeled myself off the tree, stopped my head spinning and hobbled over to the bike it had been running upside down for a good 20 to 30 seconds, I could not get to the ignition or the kill switch so had to kick the bike onto its side at which point it stalled. I pressed the start button in an attempt to rejoin the race but it turned over once and stopped, the mashalls and other riders got me off the bike as I was apparantly unable to stand let alone ride the bike and I had some injurys, the bike had some damage too.
The oil is leaking from the airbox pressumably it has gone down the rocker box breather and soaked the filter. I've not touched the bike yet but was wondering what the process should be on a bike that's been rubber side up?
Drain the oil from the airbox and breather tubes, refill and start up?

Any input from those who have turned their bike the wrong way appreciated.

Trevor.
 
Just an idea, the cylinder may be filled with oil, maybe you could pull the spark plug and see if it is. Don't force the engine to turn because liquid is not compressible and engine damage will result.

I did think of that at first but there is no way that the oil can get in combustion chamber apart from past the rings or the valve guides. Obviously the rocker box would have been full but that will have all drained back down with in seconds once the bike was righted.

It is more of a precaution. Say some oil did sneak past your ring. Trying to start it, you may bend / ruin lots of other pretty, expensive itmes in the process.. Like stated, a full inspection, before trying to start is recomended.
 
I have crashed my TE into an upsidedownish position before. It stalled immediately, but ended up laying in that position for over a minute. Lots of oil ran out of the engine and into the airbox. and all over the swingarm and frame before the bike got righted. It took a few minutes before I could get the bike to fire up, then a few more minutes before the exhaust cleared of thick blue smoke from all the oil that got in through the carburetor via the airbox. When I got back to the staging area, I found that I had lost close to half of my engine oil in that fall. I always keep a quart of oil in stashed in the Jeep since that happened.

The bad thing about your crash is that the engine kept running after it was upsidedown. I hope that it was running at fairly low RPMs. A friend of mine crashed a bike upsidedown once, but it was still running at really high RPMS for almost a minute. The oil pump pickup was high and dry in that position, so the crank was not getting any lubrication while the engine was running wide open. Within a couple more rides, the lower end of the motor went out on that machine.:(
 
Ok, i've thought again. It's upside down, oil runs through the air filter, through the throttle body and into the cylinder through an open inlet valve causing hydro lock??
Just need to find a spanner small enough to get that damn spark plug out!!
 
Since the new bikes are FI they will run upside down and as you note the cam cover will fill with oil and the oil pickup will run dry....not a good scenario. I'd guess as long as there was still a good amount of oil in the motor and it was only idling it should be okay.
 
Glad to see you fixed it my advice would have been the same as if you had drowned it in a stream. Pull the plug flip it over and with the bike in gear spin the rear tire to pump out anything in the cylinder. Then flip it back over and put the plug back in and hurry up because your buddies are sick of waiting for you!:naughty:
 
If you can push it thru with k-start it's not hydro'd
With bikes with mechanical decomp just pull it open kick it thru. Or magic button it for a few seconds.
Later George
