She sure was, R.I.P

What was the plug used for....

Wow, sorry to hear about your motor. After that video it occured to me that you "leaned things out" prior to finding that plug b/c you were so rich it was "off the charts". Did you ever richen things up AFTER you plugged in that thing? Or even check the A/F again? Perhaps you were running way lean after the fix causing the motor failure.

Where did you purchese the kit from?

jdback19

It controls the butterfly valves in the intake. With it unplugged it only lets in 20% air flow.

So did you richen up your AF after you put the plug back in?

Did you buy the hellion kit from brenspeed? This is the second hellion to blow on here, but I think we might have to blame you a little for this one.

When I leaned it out on the dyno it put the A/F where it was supposed to be at. When i pluged it back in a put the car back to where it was suppossed to be. With the engine apart it is easy to see what happened. It was indeed the 87 octane my dad put in the motor, it started pinging and shattered the number 7 piston it also put a bend in the wrist pin and cracked it into 3 pieces. You can see were the rod rattled around in the cylinder and then it destroyed the cage thats around the crank. The it smashed into one side of the block and made a crack then it smashed the other side of the block making a quarter sized hole and snapping the rod in half. Thats the time line that i have put together. I knew once i left my fathers house with the 87 octane that the car was running wierd. I can also garuntee that if it wasnt for the bad gas the car would still be kickin *** right now.

I am taking the engine down tomorrow so they can start the rebuild.

Love the video, music really captures the sorrow of when your motor broke down. Dude you had me crying for a minute, then I cheered up when you took it to the dyno shop . Hope everything goes well on the rebuilt engine!!

And for the record the wrist pins that are in this engine are ridiculous!!! The wrist pin in my YZ125 is thicker and bigger than these.[&:]
