Factory on left new bearing on right is slightly taller I wish I had a micrometer ...

I prob should ditch the washers and kust run bearings, piston should center itself please comment if you are a experienced engine builder..thanks

There are different types of bearings some use the washers others do not.
I want ti say the older 650 ones did not use washera and were bigger.

I dont remeber using washers on my 701 a year ago

The wrist pin bearings fit snug without washers ..

The SBT bearings are wider and do not require the use of the thrust washers

early 650 use the wider pin bearing that dont use washers
sbt crank pin bearings do come with the wider bearings
they are kaw 750 bearings
wiseco b1023 is the part # for the wider bearings to use and eliminate the useless washers
