This would do great justice in the Yamaha forum as well...the tranny and one way gear leave a lot of metal that gets stoped by this screen...If it became plugged Kaboooom!! Or if those flake manage to pass the continue to cause damage

 

Bigger, this is exactly how i blew my bottom end on my original 720, that is why it is a 763 now!!!i have mentioned something about this in the past... i looked at this new 720 and barely caught it in time, it was almost clogged and i think an engine re-build enhances the debri to clog res filter amoung other things, such as the re-useage of oil filters ect.GREAT POST, it will save peoples motors

 

the problem with the Raptor is you cant get to the oil screen without breaking the cases.

 

No No the oil screen thats in the oil tank...not the motor screen

 

400ex too. I imagine a z400 as well, make that all dry sump motors. I have seen a 400 ex with a cooked motor all because of theat screen. I check mine every time I change the oil.
GREAT ADVICE! Thanks Bigger

 

Oh, so there is an oil tank screen on the Raptor? I had better check mine then. Thanks.

 

Thanks , will check today

 

Ya it is very easy to check and clean mine seemed like it had never been cleaned before.
Good tip.






THANKS!!!!!!!!!

 

I have always checked mine about every three oil changes...... Mine barley ever had ANY shavings or crud in it.... That's good.

 

I truly believe this is the cause of my blown rod bearing also!

When I checked the screen after Tony told me about it, it was almost completely clogged.

I yanked the damn thing off. I'll just make sure I change my oil more often, if I ever get the engine back and/or don't sell it.
