Question about thrust washers

[sledder325]

I am rebuilding a 2008 800r ptek motor, i am going to use spi pistons instead of brp pistons. my question is should i use the thrust washers from the brp pistons set up i have not received the spi pistons yet and my past experience well ordering a rebuild kit i did not get thrust washers with it.
are thrust washers necessary?

Huh, do you mean the washers on either side of the piston pin bearing??

As in cageless stock bearings

Yeah i was further looking on brp parts website and i c they dont have them, and actually now that i recall i saw them on my 670 when i rebuilt the engine and it had cageless needle bearings, i guess they just use them on cageless needle bearings
