Heres a little history.
It was bought new in jan 03
I replaced the crank bolts with studs and locktited the tranny bolts in feb 03. It ran for 320 hours with oil and filter changes averaging every 10 t0 15 hours. (thats a lot of filters) mobil 1 oil mostly.
Nothing else was done engine wise. Stock speed map.1700 miles before it blew I found aluminum flakes in the oil filter then it went away.
The engine let go halfway up the steep right side of choke cherry hill in ST Anthonies Idaho.
I have it on video if you want it I can email it to you or post it on Kazza. I dont know if Jaybr posted it on the video section yet but Ill ask him. I was running way to tall gearing and had to drop it in 1st and let it rev to even climb most of the tall dunes.
The engine will rotate about half a turn free and then jam .
Post your answer to as what you think is the exact cause of the failure. I will pull the motor this weekend and examine it . If you have any other questions about this quads history let me know. Good luck.
