    Hmm sounds terminal matey, im afraid to say. IF you were riding flat out and it just cut out and rolled to a stop. Did it give any hesitation just before it cut out ? Was there any difference in engine note before or during the cut out ?

    I'd rip the barrel off and check that you aint scored the bore. Check the rings, plug etc. But in most of the 'blows' we have had this backfire is common place. 4 of our engines did this and it was the crank bearings that had gone. Crankshaft had just enough movement to pivot on its axis which in turn nipped the barrel and caused a split second sieze. Result bottom end build, barrel hone, new piston, rings and gasket set.

    Hope this helps mate.

My o6 polaris outlaw500 cuts back when full throttle not allowing me to reach full speed in any gear,what could cause this??? Jets are clean..

If it's fuel injected then it could be a computer prob, in which case I suggest unplugging the battery and waiting a few seconds before reconnecting it, but if it's carbed then try adjusting the throttle screw. Or if it's fuel injected and unhooking it fails it would have to have the TPS (throttle position sensor) replaced. Hope I help ya out!

sounds like you might need to rebuild the top end and check the rod bearings remember when doing a top end always change piston and rings and use new base and head gasket
