ATTENTION! CRITICAL 2010 TC/TXC/TE info

I pulled the valve cover on my '10 TC 250 last night just to see what was underneath http://www.cafehusky.com/forums/showthread.php?t=6324.

This afternoon I put everything back together (or so I thought) and kicked it ONCE to start it up. After about 25 seconds of the motor running flawlessly, I notice a puddle of warm oil developing under the bike before my very eyes!



I immediately shut the bike down and start investigating and find this lying on the jackstand:



I immediately disassemble down to the valve train and start looking around to find the place that the "extra part" goes....






When I took the valve cover off the first time, it was NOT obvious that the gasket was part of the process. Thank God it fell on the jackstand in an obviously visible location.

Now you know!

Great find! Thanks.

Hey thanks for posting that and as always with pics.

That had to be what happened.

Might not hurt to take a bit of high temp RTV silicone and glue that gasket to the valve cover..........??

Great insight, I'll be ready for that one now when I check top end.

Thanks!

If you do go that route make sure it is applied paper thin. Any excess is going to end up down by the screen, most likely. Those type of machined mating surfaces normally call for an anaerobic sealant. Those sealants seal with the abscense of air and dissolve in the oil.

Good pick up and great that you bothered to take pictures. Well done.

My issue is I had to remove the valve cover and remove this seal just to get the plug out. I've tried so many sockets and can't get down past that seal.

Also, did you cut off that clip that attaches the breather tube to the valve cover?

I left it attached and just let the cover dangle.
