Exhaust valve carnage

[fredster]

Got the sled back from the dealer today, running fine again after the mag side VES valve broke and 'modified' the piston. Check out the pics, about half of the VES valve was gone. Most of it is now on top of the piston...not sure where the rest went.....

Pic 1 doesn't look like the same valve??

 

[fredster]

There are two valves in the picture. The upper valve is intact and came out of the PTO cylinder - both valves were replaced since the Mag side failed. The other valve - well that's all that is left of it! Most of what's missing is welded to the piston shown in the other pictures.....if you look closely you'll also see where it broke which was what started all the fun.....

what was that price tag

 

[tom_s]

wow

Have you ever had them out for a cleaning or inspection. Hopefully none of the E.Valve got into the crank. It look's like it stayed on top of the piston. How are the cylinder's?

 

[fredster]

I cleaned them 2X in 2500 miles, and they were never very dirty. No sign of trouble before the mag side broke. Sled is my wife's so it's had an easy life. Dealer did the work, said the cylinder was OK, had to replace piston for obvious reasons! Replaced other piston at same time, as well as both valves. Hopefully this engine won't have to apart again for a very long time.......

how many miles when that happened. if i had to guess maybe 6000-8000 miles??? new ones are stainless i do believe so you shouldnt have that problem again.

 

[fredster]

Only 2500 miles (2005 600 Classic) and my wife's sled which gets babied more than anything...yes it was a big surprise.....

Valves

That sucks. Did it give you any warning or just let go?

 

[fredster]

No warning. I was riding it (wife was cold and my handwarmers are hotter) and just tooling along at 50-55. Engine note suddenly changed, I knew something was wrong, got out of the throttle and coasted to a stop. Just as the sled stopped moving, the engine locked up. :-(

how much do the valves cost?

That very same thing happen to my buddy on to of brockway mountin by copper harbor, just this weekend.

Thanks for the people who drove him and his sled back to mass city.

 

[fredster]

List price is over $90 for the valve itself. Much cheaper than rebuilding a cylinder though!
