"Welcome to the Powroll Tech Guru's Hall of Shame.  I am Igor, your tour guide for the afternoon.  Everyone please drop your vehicle keys in the bag for safekeeping.  Now stay together and keep close.  Do not touch the exhibits.  If you do get separated from the group, we will notify your next of kin.  The dogs are released promptly at 5:30 every evening, so be certain to have elderly guests and children off the grounds by that time.  We wouldn't want any more tragic accidents, now would we?

We have entered our first exhibit hall.  Will the last person through the door please close it.  The lock, make sure to secure the lock.  Yes, thank you...that's much better..."

Our first item is one of the primary exhibits of the Hall of Shame.  This gruesome sight may be too much for ladies with delicate constitutions; those of you who are prone to fainting fits please acquaint yourselves with the location of chairs and benches on your left along this wall.

This is the famous Triumph Headless Valve.

Note the valve head is actually imbedded in the dome of the piston.  The high velocity at which the engine was rotating at the exact moment of destruction caused the damage you see here.  Complete engine failure resulted.

This next exhibit is not nearly as visually abhorrent as the first.  It is the circumstances which makes it so awful to contemplate.

The ATV which these parts were removed from was brought in to the shop.  The owner complained of a reduction of power.  The only symptom stated was 'a slight rattling noise'.

Upon removal of the head - this horribly mangled piece of aluminum came into view.

Terrible and amazing as it may sound, the engine STILL RAN in this condition!

Upon further questioning, it was determined the owner installed a high compression big bore kit without rejetting!  He was under the mistaken impression that it was impossible to seize a four stroke.

This concludes today's portion of our tour.  You are welcome to spend the night and continue with us tomorrow.

Those of you who wish to leave can do so by the same door you entered through...oh, why yes, it IS locked, isn't it?  Well, I guess we're all staying then.  The owner wishes to have you all for dinner.  Oh, rather, he wishes to have you all STAY for dinner.  Terribly sorry!  This way please..."
