I have a question:

What could cause lack of Lubrication (Yamaha Raptor) to the TOP END

Supposidely OIL PUMP IS OK

and HAD OIL

CAM SHAFT WELDED IN HEAD and BROKE IN HALF

A couple questions/comments that come instantly to mind...how do you know the oil pump is ok?? what age/condition/type of oil was in it? does the water pump work?? coolant?? what do the cylinders / sleeves and valves look like?? how old is the raptor? Still have a warranty?

What exactly does it sound like when that happens? just to satisfy my own morbid curiousity.

Good Luck!

I personally saw the Oil Pump everything Ok, Dealer has bike apart and according to them too Pump is OK

According to them Oiling Problem like run low on OIL or No Oil, which is not true

Yes have warranty thru WSC (they denied it)

Obviously something went wrong for the cam to be Welded to the head and Broke in Half (Bottom Half of Motor everthing seems ok)

Oh yeah it is a 2001
