WSM crank and needle bearing question

[Yamadogggy]

just rebuilt my 61x with a wsm crank and wsm piston. I used the new wrist pin bearings that came with crank. I was following the manual and used Oem thrust washers on the new bearing. After reading i see people say they aren't needed. I already have everything back together and am wondering if they're going to hurt anything. Pin slid right through everything is smooth good compression. Should I tear it back apart or can I ride this 4th? Thanks!

From my experience the thrust washers won’t fit with AM bearings but if they went in really easy then you will be fine. If you had to push them in with any resistance then no bueno.

Okay awesome thank you. They weren't in there before. I just had them and figured I'd try them and they went in pretty easy, but snug. Hopefully its all good.

Yeah no thrust washers with the wsm pistons
